Configuration Guide - Reliability
Data Preparation
To complete the configuration, you need to configure the priority of the standby interface.
Procedure
Step 1 Configure the network layer attributes.
# Configure IP addresses for routers as shown in
The configuration details are omitted here.
# Configure a static route to Host B network segment on Router A.
<RouterA> system-view
[RouterA] ip route-static 10.20.1.0 255.255.255.0 pos1/0/0
[RouterA] ip route-static 10.20.1.0 255.255.255.0 pos2/0/0
[RouterA] ip route-static 10.20.1.0 255.255.255.0 pos3/0/0
# Configure a static route to Host A network segment on Router B.
<RouterB> system-view
[RouterB] ip route-static 10.10.1.0 255.255.255.0 pos1/0/0
[RouterB] ip route-static 10.10.1.0 255.255.255.0 pos2/0/0
[RouterB] ip route-static 10.10.1.0 255.255.255.0 pos3/0/0
# Configure Host A and Host B to use Router A and Router B as their gateways respectively.
The configuration details are omitted here.
After the configuration, Host A and Host B can ping through each other.
Step 2 Configure the interface backup on Router B.
# Configure POS 2/0/0 as the active interface and POS 1/0/0 and POS 3/0/0 as the standby
interfaces. POS 1/0/0 has a higher priority. Immediate switching is adopted.
[RouterB] interface pos 2/0/0
[RouterB-Pos2/0/0] standby interface pos1/0/0 40
[RouterB-Pos2/0/0] standby interface pos3/0/0 20
[RouterB-Pos2/0/0] quit
After the configuration, display the state of the active/standby interfaces, and you can find that
POS2/0/0 is UP, and POS 1/0/0 and POS 3/0/0 are STANDBY.
[RouterB] display standby state
