Huawei Router: Setting RSTP Parameters That Affect RSTP Convergence

Huawei Router such as AR28-11: Setting RSTP Parameters That Affect RSTP Convergence

RSTP implements rapid convergence by configuring the link type of a port and fast transition
mechanism.
 
1 Setting the RSTP Network Diameter
Context
On a switched network, any two terminals on the switching network are connected through a specific path along which multiple devices reside. The network diameter is the maximum number of devices between any two terminals. A larger network diameter indicates a larger network scale.
An improper network diameter may cause slow network convergence and affects
communication. Run the stp bridge-diameter command to set a network diameter based on the network scale, which helps speed up convergence.
It is recommended that all devices use the same network diameter.
Procedure
Step 1 Run:
system-view

Huawei Router: Setting STP Parameters That Affect STP Convergence

STP cannot implement rapid convergence. However, you can set STP parameters including the network diameter, timeout interval, Hello timer value, Max Age timer value, and Forward Delay timer value, especially for the Huawei 3G router.

Huawei Router: Configuring Basic STP/RSTP Functions

The Spanning Tree Protocol (STP) trims a ring network into a loop-free tree network. It prevents replication and circular propagation of packets. The Rapid Spanning Tree Protocol (RSTP) was developed based on STP to implement faster convergence. RSTP defines edge ports and provides protection functions. Huawei NE20 and Huawei NE40-X3 works well for this configuration, too.
 
Configuring basic STP/RSTP functions, you can follow the steps as below:
 
1 Configuring the STP/RSTP Mode
The device supports three working modes: STP, RSTP, and MSTP. A switching device can
select only the STP mode on a ring network running only STP, and can select only the RSTP mode on a ring network running only RSTP. In other scenarios, the MSTP mode is used by default.
Procedure
Step 1 Run:
system-view
The system view is displayed.
 
Step 2 Run:

Example for Configuring GVRP on Huawei Router

How to Configuce GVRP for Huawei Router, I use the AR3200 most time on the network, here is the example for you:

Networking Requirements

As shown in Figure 1, company A, a branch of company A, and company B are connected

using switches. To implement dynamic VLAN registration, enable GVRP. The branch of

company A can communicate with the headquarters using RouterA and RouterB. Company B can communicate with company A using RouterB and RouterC. Interfaces connected to company A allow only the VLAN to which company B belongs to pass.

Figure 1 Networking diagram of GVRP configuration



Configuration Roadmap

The configuration roadmap is as follows:

1. Enable GVRP to implement dynamic VLAN registration.

S2700-26TP-EI Gigabit Combo Problem

Question: If you enable the switch s27/37/57 all of the above Gigabit Combo ports, it means that there is some port would be closed automatically and cannot use. Right?

Do you know what command to enabled the switch?

 

Answer:

Suggestions in the interface, forced the specified interface mode:

Combo-port copper: electricity interface

Combo-port fiber: optical interface

Personally think that Huawei electrical and optical two modes, the presence of auto bug. they often have to manually specify.

How to Configure VLAN ID-based QinQ Stacking on Huawei Router

How to Configure VLAN ID-based QinQ Stacking on Huawei Router
Background
QinQ mitigates VLAN ID shortage and is widely applied when users connect to carrier networks.
When private networks connect to a carrier network through CEs and PEs, run the qinq
stacking command on CE interfaces connected to PEs so that the CE interfaces add the outer VLAN tag allocated by the carrier to user packets. This implementation saves VLAN IDs and allows user packets to be transparently transmitted on the carrier network.
 
The configuration overview:
Step 1 Run:
system-view
The system view is displayed.
 
Step 2 Run:
bridge bridge-id
A bridge group is created and the bridge group view is displayed.
 
Step 3 Run:
quit
Exit from the bridge group view.
 
Step 4 Run:
interface { ethernet | gigabitethernet }.subinterface-number
