Configuration Guide - Reliability
Procedure
Step 1 In this example, the configuration procedure for establishing the multi-device backup platform
on Router A is provided. The configuration of Router B is similar to that of Router A.
# Configure a BFD session on the access side to rapidly detect interface or link faults and trigger
a master/backup VRRP switchover when detecting a fault. Set the IP address of GE 1/0/0 on
Router B to 100.0.0.2.
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] bfd bfd bind peer-ip 100.0.0.2
[RouterA-bfd-session-bfd] discriminator local 1
[RouterA-bfd-session-bfd] discriminator remote 2
[RouterA-bfd-session-bfd] commit
[RouterA-bfd-session-bfd] quit
# Bind GE 1/0/0 to the VRRP backup group. Configure VRRP to monitor the BFD session status
and network-side interface status.
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] vlan-type dot1q 200
[RouterA-GigabitEthernet1/0/0] ip address 100.0.0.1 255.255.255.0
[RouterA-GigabitEthernet1/0/0] vrrp vrid 1 virtual-ip 100.0.0.100
[RouterA-GigabitEthernet1/0/0] admin-vrrp vrid 1
[RouterA-GigabitEthernet1/0/0] vrrp vrid 1 priority 120
[RouterA-GigabitEthernet1/0/0] vrrp vrid 1 preempt-mode timer delay 600
[RouterA-GigabitEthernet1/0/0] vrrp vrid 1 track bfd-session 1 peer
[RouterA-GigabitEthernet1/0/0] vrrp vrid 1 track interface gigabitethernet 2/0/0
reduced 50
[RouterA-GigabitEthernet1/0/0] quit
# Configure the RBS.
[RouterA] remote-backup-service service1
[RouterA-rm-backup-srv-service1] peer 88.88.88.88 source 22.22.22.22 port 2046
[RouterA-rm-backup-srv-service1] track interface gigabitethernet 2/0/0
# Configure an RBP.
[RouterA] remote-backup-profile profile1
[RouterA-rm-backup-prf-profile1] peer-backup hot
[RouterA-rm-backup-prf-profile1] vrrp-id 1 interface gigabitethernet 1/0/0
[RouterA-rm-backup-prf-profile1] backup-id 10 remote-backup-service service1
[RouterA-rm-backup-prf-profile1] service-type arp
[RouterA-rm-backup-prf-profile1] quit
Step 2 Bind the RBP to the user access interface. In this example, GE 1/0/0 is used and the configuration
of Router A is provided. The configuration of Router A is similar to that of Router B.
[RouterA] interface gigabitethernet 1/0/0
[RouterA-GigabitEthernet1/0/0] remote-backup-profile profile1

NOTE
In this example, only the configuration procedure for user information backup is provided.
NOTE
To differentiate master and slave devices, set different VRRP priorities on the two devices. The device
with a higher VRRP priority is the master device.
NOTE
The master and slave devices can successfully ping each other.
As an alternative of running the track interface command, the track-bfd-session command can be run in
the RBS view of the master and slave devices to track the status of the peer BFD session. In this manner,
the access side of the master and slave devices can be rapidly detected. In this example, the configuration
procedure is not provided.
