Configuration Roadmap

The configuration roadmap is as follows:

Data Preparation

To complete the configuration, you need the following data:

Step 1 Assign IP addresses to the interfaces directly connecting Router A and Router B.

# Assign an IP address to the interface on Router A.

<HUAWEI> system-view

[HUAWEI] sysname RouterA

[RouterA] interface gigabitethernet 1/0/0

[RouterA-GigabitEthernet1/0/0] undo shutdown

[RouterA-GigabitEthernet1/0/0] ip address 10.1.1.1 24

[RouterA-GigabitEthernet1/0/0] quit

# Assign an IP address to the interface on Router B.

<HUAWEI> system-view

[HUAWEI] sysname RouterB

[RouterB] interface gigabitethernet 1/0/0

[RouterB-GigabitEthernet1/0/0] undo shutdown

[RouterB-GigabitEthernet1/0/0] ip address 10.1.1.2 24

[RouterB-GigabitEthernet1/0/0] quit

Step 2 Configure a BFD session with the one-arm Echo function.
