Configuration of HSRP
2-6
xx-xx-xx-xx-xx indicates the first 5 bytes of other virtual MAC addresses, the last byte
being the hot standby group’s number. The setting is valid for all HSRP hot standby
groups on the configured Ethernet interface.
2.3 Monitoring and Maintaining HSRP
After the configuration, the following commands can be used to turn on the debug
switch of HSRP or display relevant information of HSRP so as to monitor a nd maintain
HSRP.

The above information includes the standby group that the interfac e be lon gs to, stat e,
virtual IP address, priority, preemption, hold-time, hello-time, and virtual MAC address.
Note:
As output of the debugging information affects router’s running efficiency, please don’t turn on the debug
switch unless necessary; and please turn it off after debugging.
2.4 Typical Configurations of HSRP

2.4.1 An example for single hot standby group configuration

I. Networking requirements
As shown in the following diagram, hosts A and B take the hot standby group, which
consists of Routers A and B, as its default gateway (i.e., specify virtu al IP address
202.38.160.111 as its gateway IP address), and they access host C on Internet through
this gateway. Normally, it is Router A that fulfils the tasks of the gateway as an active
router, if Router A switches off or breaks down, Router B will take over its tasks.
Specific parameters of HSRP hot standby group: standby group number is 0, virtual IP
address is 202.38.160.111. Router A is an active router with a priority of 120, and its
HSRP is set as preemption so that it can go on with the gatewa y’s task as an act ive
router after it restores. Router B is a backup router, set as preempted without a priority
(i.e., its priority has a default value of 100).
