How to Configure IPv6 Services in the FTTB+HGW Scenario

This section describes the methods for configuring IPv6 services in the FTTB+HGW scenario. Works for Huawei MA5683T, Huawei MA5680T, Huawei MA5608T, Huawei MA5603T...

 

Application Scenario

The FTTB+HGW networking includes two scenarios: The ONU provides the voice service in one scenario and the HGW provides the voice service in another scenario. After IPv6 is introduced to the network, the voice service still uses IPv4 so that these two voice scenarios do not change after IPv6 introduction.
 

FTTB+HGW Application Scenario

Figure 1 shows an FTTB+HGW network. The Huawei OLT is deployed at the CO and connects to the MAN by aggregation, and the ONU is deployed in the buildings or street fiber distribution terminals. Access interfaces are deployed on the HGW that connects to the ONU using LAN or xDSL upstream transmission (deployed in user houses). Together with upper layer devices, the FTTB+HGW network supports the HSI and IPTV services implemented by the schemes of the Huawei fixed broadband solution for IPv6: IPv4/IPv6 DS+NAT+PPPoE, IPv4/IPv6 DS+NAT +IPoE, and DS-Lite+PPPoE (for the HSI services) and IPv4/IPv6 DS+IPoE and IPv4/IPv6 DS +PPPoE (for the IPTV service).

1 Upstream networking: The HGW connects to the ONU through upstream ETH or xDSL port.

 

2 HSI service: The HGW has Layer 3 functions (such as PPPoE dial-up and NAT), which enable multiple PCs of a family to access the Internet at the same time.

If the HGW uses the IPv4/IPv6 DS scheme, the PPPoE or IPoE channel that supports

both IPv4 and IPv6 is established between the HGW and the BRAS. The OLT and ONU perform Layer 2 forwarding, irrespective of whether the access service is IPv4 or IPv6.

Service configurations for IPv4 and IPv6 are the same. Only the ACL, anti-IP spoofing,

and DHCP option configurations for IPv4 and IPv6 are different.

If the HGW uses the DS-Lite scheme, the PPPoE channel that supports only IPv6 is

established between the HGW and the BRAS. As for IPv4, the HGW encapsulates IPv4 packets and transmits them to the BRAS or CGN using the 4in6 tunnel. The OLT and ONU perform Layer 2 forwarding, irrespective of whether the access service is IPv4 or IPv6. Service configurations for IPv4 and IPv6 are the same. Only the ACL, anti-IP spoofing, and DHCP option configurations for IPv4 and IPv6 are different.

 

3 IPTV service: Users can preview or view IPTV programs by connecting an STB to the HGW. STB supports IPv4/IPv6 DS and uses IPv4 or IPv6 (cannot be used together) to carry IPTV services.

If the STB uses IPoE, choose the ONU preferentially to duplicate multicast flows. On

the ONU, IPv6 and IPv4 multicast services are configured in the same way but with

different commands. On the OLT, service channels to the ONU need to be established,

multicast flows do not need to be duplicated, and IGMP IPv6 data needs to be

configured.

If the STB uses PPPoE, it establishes a PPPoE connection to the BRAS. The OLT, ONU, and HGW only forward PPPoE service flows and do not process multicast services.

Therefore, this scheme is not recommended.

 

4 Voice service: The voice service can be provided by the ONU with the build-in voice

module or the build-in IAD of the HGW. The VoIP service on ONU or HGW is still

implemented by IPv4.

FTTB+HGW (ONU Provides the Voice Service) Configuration Procedure

The following figure shows the IPv6 service configuration procedure in the FTTB+HGW (ONU provides the voice service) scenario. In this scenario, the planning and configuration procedure/ method for IPv6 and IPv4 services are almost the same except the following differences. On the OLT side, multicast service channels between the OLT and ONU and part configuration commands of the security policy are different. On the ONU side, configuration commands of IPTV multicast services are different

Procedure

Step 1 Configure GPON ONU profiles.

1. Configure a DBA profile.

huawei(config)#dba-profile add profile-name fttb_dba type3 assure 8192 max

20480

2. Configure an ONU line profile.

huawei(config)#ont-lineprofile gpon profile-id 10 profile-name fttb(c)

huawei(config-gpon-lineprofile-10)#tcont 4 dba-profile-name fttb_dba

huawei(config-gpon-lineprofile-10)#gem add 11 eth tcont 4 cascade on

huawei(config-gpon-lineprofile-10)#gem add 12 eth tcont 4 cascade on

huawei(config-gpon-lineprofile-10)#gem add 13 eth tcont 4 cascade on

huawei(config-gpon-lineprofile-10)#gem mapping 11 0 vlan 8

huawei(config-gpon-lineprofile-10)#gem mapping 12 1 vlan 1001

huawei(config-gpon-lineprofile-10)#gem mapping 13 2 vlan 200

huawei(config-gpon-lineprofile-10)#commit

huawei(config-gpon-lineprofile-10)#quit

3. (Optional) Add an alarm profile.

EchoLife GPON Terminal Service Manual 3 Configuration Issue In this example, the default alarm profile is used and therefore the configuration of the alarm profile is not required.

 

Step 2 Add an ONU to an OLT.

Assume that the ID of GPON port 0/2/1 is 1, SN is 32303131B39FD641, management mode is SNMP, and the bound line profile is fttb(c). Connect the ONU to such a GPON port through the optical splitter.

There are two modes to add an ONT: add an ONT offline and confirm an automatically

discovered ONU.

1 Add an ONU offline.

huawei(config)#interface gpon 0/2

huawei(config-if-gpon-0/2)#ont add 1 ontid 1 sn-auth 32303131B39FD641

snmp ont-lineprofile-name fttb(c)

 

2 Confirm an automatically discovered ONU.

huawei(config)#interface gpon 0/2

huawei(config-if-gpon-0/2)#port 1 ont-auto-find enable

huawei(config-if-gpon-0/2)#display ont autofind 1

huawei(config-if-gpon-0/2)#ont confirm 1 ontid 1 sn-auth 32303131B39FD641

snmp ont-lineprofile-name fttb(c)

 

3 (Optional) Bind the alarm profile to the ONU.

In this example, default alarm profile 1 is used and therefore the configuration of the alarm

profile is not required.

 

Step 3 Check the ONU status.

After an ONU is added, run the display ont info command to query the current status of the ONU. Ensure that Config flag of the ONU is active, Run State is online, and Config state is normal.

huawei(config-if-gpon-0/2)#display ont info 1 1

---------------------------------------------------------------------

F/S/P : 0/2/1

ONT-ID : 1

Control flag : active //The ONU is activated.

Run state : online //The ONU is online.

Config state : normal //The ONU configurations are recovered

normally.

...//The rest of the response information is not provided here.

huawei(config-if-gpon-0/2)#quit

 

Step 4 Configure the inband management VLAN and IP address of the OLT.

huawei(config)#vlan 8 smart

huawei(config)#vlan priority 8 6

huawei(config)#interface vlanif 8

huawei(config-if-vlanif8)#ip address 192.168.50.1 24

huawei(config-if-vlanif8)#quit

 

Step 5 Configure the inband management VLAN and IP address of the ONU.

huawei(config)#interface gpon 0/2

huawei(config-if-gpon-0/2)#ont ipconfig 1 1 static ip-address 192.168.50.2 mask

255.255.255.0 gateway

192.168.50.254 vlan 8

huawei(config-if-gpon-0/2)#quit

 

Step 6 Configure an inband management service port.

huawei(config)#service-port 1 vlan 8 gpon 0/2/1 ont 1 gemport 11 multi-service

user-vlan 8 rx-cttr 6 tx-cttr 6

 

Step 7 Confirm that the management channel between the OLT and the ONU is available.

l On the OLT, run the ping 192.168.50.2 command to check the connectivity between the

OLT and the ONU. The ICMP ECHO-REPLY packet from the ONU should be received.

l On the OLT, you can remote log in to the ONU to perform the configuration.

 

Step 8 Configure a channel for the Internet access service.

huawei(config)#vlan 100 smart

huawei(config)#vlan attrib 100 stacking

huawei(config)#port vlan 100 0/19 0

huawei(config)#service-port vlan 100 gpon 0/2/1 ont 1 gemport 12 multi-service

user-vlan 1001 tag-transform default rx-cttr 6 tx-cttr 6

 

Step 9 Configure a channel for the Voice service.

huawei(config)#vlan 200 smart

huawei(config)#port vlan 200 0/19 0

huawei(config)#traffic table ip index 9 cir off priority 5 priority-policy localsetting

huawei(config)#service-port vlan 200 gpon 0/2/1 ont 1 gemport 13 multi-service

user-vlan 200 rx-cttr 9 tx-cttr 9

 

Step 10 Configure a channel for the VoD service.

huawei(config)#vlan 300 smart

huawei(config)#port vlan 300 0/19 0

huawei(config)#traffic table ip index 10 cir off priority 4 priority-policy local-

Setting huawei(config)#service-port vlan 300 gpon 0/2/1 ont 1 gemport 14 multi-service user-vlan 300 rx-cttr 10 tx-cttr 10

 

Step 11 Configure a channel for the multicast service.

huawei(config)#vlan 1000 smart

huawei(config)#port vlan 1000 0/19 0

huawei(config)#service-port vlan 1000 gpon 0/2/1 ont 1 gemport 14 multi-service

user-vlan 1000 rx-cttr 10 tx-cttr 10

huawei(config)#btv

huawei(config-btv)#igmp cascade-port 0/2/1 ontid 1 gemport-index 14

huawei(config)#multicast-vlan 1000

huawei(config-mvlan1000)#igmp ipv6 version v2

huawei(config-mvlan1000)#igmp ipv6 mode proxy

Are you sure to change IGMP IPv6 mode?(y/n)[n]:y

huawei(config-mvlan1000)#igmp uplink-port 0/19/0

huawei(config-mvlan1000)#igmp program add batch ipv6 ff15:: to-ipv6 ff15::ffff

source-ipv6 2000::1

 

Step 12 Configure LAG for upstream ports.

Configure upstream ports 0/19/0 and 0/19/1 into an aggregation group. Each member port in the aggregation group allocates packets based on the source MAC address. The working mode is LACP static aggregation.

huawei(config)#link-aggregation 0/19 0-1 ingress workmode lacp-static

 

Step 13 (Optional) When PPPoE is adopted, enable forwarding the packets with PITP tag on the OLT equipment.

huawei(config)#pitp permit-forwarding service-port 101 enable

 

Step 14 (Optional) When IPoE is adopted, enable forwarding the packets with DHCP option on the OLT equipment.

huawei(config)#dhcp-option82 permit-forwarding service-port 101 enable //For IPv4

packets

huawei(config)#dhcpv6-option permit-forwarding port 0/2/1 ontid 1 enable //For

IPv6 packets

 

Step 15 Save the configuration data on the OLT.

huawei(config)#save

 

Step 16 Log in to and configure the ONU.

You can remote log in to the ONU from the OLT to perform the configuration. By default, the user name is root and the password is mduadmin.

 

NOTE

The following steps are configured on the ONU side.

 

Step 17 Configuration the HSI service on the ONU side.

 

NOTE

This example creates one service port as an example. Each service port maps a user. When configuring another service port, map the corresponding SVLAN.

huawei(config)#vlan 1001-1016 smart

huawei(config)#port vlan 1001-1016 0/0 1

huawei(config)#traffic table ip index 8 cir 4096 priority 0 priority-policy localsetting

Configurations for untagged packets and packets with user VLAN tags are different.

 

1 For untagged packets, the configuration is as follows (assuming that the VLAN ID is 1001):

//Create service port 101, bind port 0/3/1 to it, set the user VLAN to

untagged, and bind traffic profile 8 to the user VLAN./ huawei(config)#serviceport

101 vlan 1001 eth 0/3/1 multi-service user-vlan untagged rx-cttr 8 tx-cttr8

2 For packets with user VLAN tags, the configuration is as follows (assuming that the user

VLAN ID is 10 and the VLAN ID is 1001):

//Create service port 101, bind port 0/3/1 to it, set the user VLAN ID to 10,

and bind traffic profile 8 to the user VLAN./ huawei(config)#service-port 101

vlan 1001 eth 0/3/1 multi-service user-vlan 10 rx-cttr 8 tx-cttr 8

 

Step 18 (Optional) Configure the PITP function for PPPoE.

huawei(config)#raio-mode common pitp-pmode

huawei(config)#pitp enable pmode

 

Step 19 (Optional) Configure the DHCP option function for IPoE.

huawei(config)#raio-mode common dhcp-option82 //For DHCPv4 packets

huawei(config)#dhcp option82 enable //For DHCPv4 packets

huawei(config)#raio-mode common dhcpv6-option //For DHCPv6 packets

huawei(config)#dhcpv6 option enable //For DHCPv6 packets

 

Step 20 Configure the voice service.

huawei(config)#vlan 200 smart

huawei(config)#port vlan 200 0/0 1

huawei(config)#interface vlanif 200

huawei(config-if-vlanif200)#ip address 17.10.10.10 24

huawei(config-if-vlanif200)#quit

huawei(config)#voip

huawei(config-voip)#ip address media 17.10.10.10 17.10.10.1

huawei(config-voip)#ip address signaling 17.10.10.10

huawei(config-voip)#quit

huawei(config)#ip route-static 200.200.200.0 24 17.10.10.1

huawei(config)#interface h248 0

Are you sure to add MG interface?(y/n)[n]:y

huawei(config-if-h248-0)#if-h248 attribute mgip 17.10.10.10 mgport

2944 code text transfer udp primary-mgc-ip1 200.200.200.200 primary-mgc-port

2944 mg-media-ip1 17.10.10.10 start-negotiate-version 1

huawei(config-if-h248-0)#reset coldstart

Are you sure to reset MG interface?(y/n)[n]:y

huawei(config-if-h248-0)#quit

huawei(config)#esl user

huawei(config-esl-user)#mgpstnuser batadd 0/3/0 0/3/23 0 terminalid 0 telno

83110001

huawei(config-esl-user)#mgpstnuser modify 0/3/0 priority cat2

huawei(config-esl-user)#quit

huawei(config)#pstnport

huawei(config-pstnport)#pstnport attribute batset 0/3/0 0/3/23 reverse-pole-pulse

enable

huawei(config-pstnport)#quit

 

Step 21 Configure the VoD service.

Create VLAN 300 with the common attribute and add upstream port 0/0/1 to the VLAN.

huawei(config)#vlan 300 smart huawei(config)#port vlan 300 0/0 1

Configure a traffic profile for the IPTV service.

The IEEE 802.1p priority of the IPTV service is 4, and rate limitation is not required. To check whether any existing traffic profile meets the requirements, run the display traffic table ipcommand. In this example, the query result shows that no traffic profile meets the requirements, so a traffic profile needs to be configured.

Add traffic profile 10 and set priority-policy to local-setting. Then, traffic is scheduled based on the priority specified in the traffic profile.

huawei(config)#traffic table ip index 10 cir off priority 4 priority-policy localsetting

Configure a service flow for the VoD service.

 

Configurations vary according to upstream interface types of HGWs.

1 If HGWs are connected to an ONU upstream through LANs and upstream packets contain user VLAN tags, the ONU needs to perform a switch between user VLAN IDs and SVLAN IDs.

Assume that the user VLAN ID is 1 and the Ethernet port is 0/3/1. Add a service flow as

follows:

huawei(config)#service-port 301 vlan 300 eth 0/3/1 multi-service user-vlan 1 rxcttr

10 tx-cttr 10

 

2 If HGWs are connected to an ONU upstream in ADSL2+ mode, upstream packets contain users' PVC information so the ONU needs to perform a switch between PVC information and SVLAN IDs.

 

Assume that the VPI/VCI is 0/35 and the ADSL2+ port is 0/2/0. Add a service flow as follows:

huawei(config)#service-port 301 vlan 300 adsl vpi 0 vci 35 0/2/0 multi-service

user-vlan untagged rx-cttr 10 tx-cttr 10

 

3 If HGWs are connected to an ONU upstream in VDSL2 mode, formats of upstream packets depend on the encapsulation mode.

 

Assume that the VDSL2 path mode is PTM mode, port is 0/1/0, and packets from the user

VLAN are untagged. Add a service flow as follows:

huawei(config)#service-port 301 vlan 300 vdsl mode ptm 0/1/0 multi-service uservlan

untagged rx-cttr 10 tx-cttr 10

Step 22 Configure the multicast service.

huawei(config)#vlan 1000 smart

huawei(config)#port vlan 1000 0/0 1

huawei(config)#multicast-vlan 1000

huawei(config-mvlan1000)#igmp ipv6 version v2

huawei(config-mvlan1000)#igmp ipv6 mode proxy

Are you sure to change IGMP IPv6 mode?(y/n)[n]:y

huawei(config-mvlan1000)#igmp uplink-port 0/0/1

huawei(config-mvlan1000)#igmp program add batch ipv6 ff15:: to-ipv6 ff15::ffff

source-ipv6 2000::1

huawei(config-mvlan1000)#quit

Configure a service flow for the multicast service.

Configurations vary according to upstream interface types of HGWs.

 

4 If HGWs are connected to an ONU upstream through LANs, assume that the user VLAN ID is 43 and the Ethernet port is 0/3/1, and add a service flow as follows:

huawei(config)#service-port 401 vlan 1000 eth 0/3/1 multi-service user-vlan 43

rx-cttr 10 tx-cttr 10

 

5 If HGWs are connected to an ONU upstream in ADSL2+ mode, assume that the VPI/VCI is 0/35 and the ADSL2+ port is 0/2/0, and add a service flow as follows:

huawei(config)#service-port 401 vlan 1000 adsl vpi 0 vci 35 0/2/0 multi-service

user-vlan untagged rx-cttr 10 tx-cttr 10

 

6 If HGWs are connected to an ONU upstream in VDSL2 mode, assume that the VDSL2 path mode is PTM mode, the user VLAN ID is 43, and the VDSL2 port is 0/1/0, and add a service flow as follows:

huawei(config)#service-port 401 vlan 1000 vdsl mode ptm 0/1/0 multi-service uservlan 43 rx-cttr 10 tx-cttr 10

huawei(config-mvlan1000)#btv

huawei(config-btv)#igmp user add service-port 401 no-auth

huawei(config-btv)#multicast-vlan 1000

huawei(config-mvlan1000)#igmp multicast-vlan member service-port 401

huawei(config-mvlan1000)#quit

 

Step 23 Save the configuration on the ONU side.

huawei(config)#save
