Configuring VRRP 1235
8
Specify the IP address that the virtual router function will use.
The router is the virtual IP address owner of this address, so the priority
value is 255 by default.
console(config-if-vlan10)#vrrp 20 ip 192.168.10.2
9
Configure an optional description to help identify the VRRP group.
console(config-if-vlan10)#vrrp 20 description backup
10
Enable the VRRP groups on the interface.
console(config-if-vlan10)#vrrp 10 mode
console(config-if-vlan10)#vrrp 20 mode
console(config-if-vlan10)#exit
console(config)#exit
Troubleshooting VRRP
When configuring VRRP, ensure that the L2 network facing the VRRP router
is up. Both VRRP peers will show as being in the “Master” state until the
layer 2 network is operational. Likewise, ensure that the link or path between
the virtual routers is operational. If the link is not operational, one VR
instance will show as “Master” and the other VR instance will show as
“Initializing.” Check the spanning-tree state on the routed links. Routed links
must show as forwarding. Disable spanning tree on the routed links if
necessary to prevent spanning tree from blocking routed links.
