5.
Configure the protection path for the network-side traffic to return.
6.
Bind the user access interface to the RBP.
Data Preparation
To complete the configuration, you need the following data:
l
VRRP backup group ID
l
IP addresses of the routers that back up each other
l
Backup ID, which is used together with the RBS to determine the RBP that the user belongs
to
Procedure
Step 1
Establish the multi-device backup platform. Take Router A as an example. The configuration
of Router B is similar to the configuration of Router A.
NOTE
Only the configurations of user information backup are mentioned here. For other configurations, refer to
related configuration guides.
# Configure the BFD session at the access side to fast detect the interface or link abnormality
and trigger the VRRP master/slave switchover. The IP address of GE 1/0/0.2 on Router B is
10.0.1.2.

# Bind the interface to the VRRP backup group. The sub-interface GE 1/0/0.2 is used here.
Configure VRRP to monitor the BFD session status and network-side interface status.

NOTE
To differentiate master and slave devices, you need to set different VRRP priorities on the two devices.
The device with higher VRRP priority is the master device.
# Configure the RBS.
