Chapter 27 Hot Standby Router Protocol and Virtual Router Redundancy Protocol

How to Configure VRRP

Router# configure terminal

Router(config)# interface Vlan10

Router(config-if)#ip address 10.10.10.22 255.255.255.0

Router(config-if)#standby 1 ip 10.10.10.20

Router(config-if)#standby 1 timers 1 4

Router(config-if)#standby 1 priority 90

Router(config-if)#standby 1 preempt delay minimum 10

Router(config-if)#standby 1 authentication cisco6

Router(config-if)#standby 1 track 1 decrement 20

Router(config-if)# end

Example: HSRP Text Authentication

The following example shows how to configure HSRP text authentication using a text string:

Router# configure terminal

Router(config)# interface Ethernet0/1

Router(config-if)#standby 1 priority 110

Router(config-if)# standby 1 preempt

Router(config-if)#standby 1 authentication text company2

Router(config-if)#standby 1 ip 10.21.0.10

Restrictions

VRRP is supported only on IPv4 devices and not IPv6 devices.

VRRP is supported only on gigabyte etherchannel interfaces of the Layer 3 SVI.

Bidirectional Forwarding Detection (BFD) protocol is not supported.

MD5 authentication is not supported.

SUMMARY STEPS

1.enable

2.configure terminal

3.interface type number

4.ip ip-address mask
