Procedure
Step 1 Configure user access functions.
For details, see AAA Configuration and Configuring IPv4 Access Authentication in the
HUAWEI NetEngine80E/40E Router Configuration Guide - User Access and configuration
files.
Step 2 Configure a VRRP backup group on the access side of two routers (BRAS1 and BRAS2) to
determine the master and backup status. Create a BFD session, and configure the VRRP backup
group to track the BFD session.
# Configure a VRRP link BFD session to rapidly detect faults in interfaces or links and trigger
a master/backup VRRP switchover.
[BRAS1] bfd zwn1 bind peer-ip 10.1.1.2

[BRAS1-bfd-session-bfd-acc] discriminator remote 6
[BRAS1-bfd-session-bfd-acc] commit
[BRAS1-bfd-session-bfd-acc] quit
# Configure a VRRP backup group on GE 1/0/0.1, and configure the VRRP backup group to
track the BFD session and a network-side interface. Enable the original master VRRP device to
preempt the Master state after 30 minutes.

NOTE
The configuration on BRAS2 is similar to the configuration on BRAS1. The configuration procedure on
BRAS1 is used in this example. For details about configurations on BRAS2, see the configuration file of
BRAS2.
VRRP parameters such as a VRID and a preemption delay
BFD parameters such as the local and remote discriminators and expected minimum
interval at which BFD Control packets are sent and received
IP address of each interface on BRAS1 and BRAS2
