DELL N3000 User Manual

Configuring VRRP

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

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.
