Versatile Routing Platform	Configuration of HSRP

!Set this router to belong to number 2 HSRP hot standby group at the same time, its virtual IP address being 202.38.160.112.

Quidway(config-if-Ethernet0)# standby 2 ip 202.38.160.112

!Set this router to work in preemption mode in number 2 HSRP hot standby group. Quidway(config-if-Ethernet0)# standby 2 preempt

!Set this router to have a priority of 120 in number 2 HSRP hot standby group. Quidway(config-if-Ethernet0)# standby 2 priority 120

2.5Fault Diagnosis and Troubleshooting of HSRP

Configuration of HSRP is not very complicated. Generally, fault can be located by viewing the configuration and debugging information:

Fault 1: impossible to ping virtual IP address.

It is normal that virtual IP address cannot be pinged on an active router, for virtual IP address is visible only from outside.

If virtual IP address cannot be pinged on other network equipment, check as follows.

zAs state conversion of HSRP requires a little time, command show standby can be used to view HSRP information to confirm that at least one router in hot standby group is in the active state.

zIf this equipment is in the same network segment as the virtual router, see if there is an ARP item of the virtual IP address in this equipment’s ARP table. If not, please check network line. If this equipment is in a different network segment, it must be confirmed if the equipment has any route to the virtual IP address or not.

zFault 2: Multiple active routers exist in the same hot standby group.

Check whether the authorization word and the timer configured on the Ethernet interface of the routers in the hot standby group are consistent.
