Basic VRRP parameter configuration
Configuring a Backup for IPv4 VRRP
To configure the VRRP Backup router for IPv4, enter the following commands.
Brocade Router2(config)#router vrrp
Brocade Router2(config)#interface ethernet 1/5
Brocade Router2(config-if-1/5)#ip-address 192.53.5.3
Brocade Router2(config-if-1/5)#ip vrrp vrid 1
Brocade Router2(config-if-1/5-vrid-1)#backup
Brocade Router2(config-if-1/5-vrid-1)#advertise backup
Brocade Router2(config-if-1/5-vrid-1)#ip-address 192.53.5.1
Brocade Router2(config-if-1/5-vrid-1)#activate
VRRP router 2 for interface is activating
Syntax: [no] router vrrp
Syntax: [no] ip-address <ip-addr>
Syntax: [no] ip vrrp vrid <num>
Syntax: [no] backup [priority <value>] [track-priority <value>]
Syntax: [no] advertise backup
Syntax: [no] activate
When you configure a Backup router, the router interface on which you are configuring the VRID
must have a real IP address that is in the same subnet as the address associated with the VRID by
the Owner. However, the address cannot be the same.
The <num> variable specifies the virtual router ID.
The priority <value> option specifies the VRRP priority for this virtual router. You can specify a value
from 3 through 254. The default is 100.
The track-priority <value> option specifies that VRRP monitors the state of the interface. You can
specify a value from 3 through 254. The default is 100.
By default, Backup routers do not send Hello messages to advertise themselves to the Master. The
advertise backup command is used to enable a Backup router to send Hello messages to the
Master.
Configuring a Backup for IPv6 VRRP
To configure the VRRP Backup router for IPv6, enter the following commands.
Brocade Router2(config)# ipv6 router vrrp
Brocade Router2(config)# interface ethernet 1/5
Brocade Router2(config-if-e10000-1/5)# ipv6-address 3013::3/64
Brocade Router2(config-if-e10000-1/5)# ipv6 vrrp vrid 1
Brocade Router2(config-if-e10000-1/5-vrid-1)# backup
Brocade Router2(config-if-e10000-1/5-vrid-1)# advertise backup
Brocade Router2(config-if-e10000-1/5-vrid-1)# ipv6-address 3013::1
Brocade Router2(config-if-e10000-1/5-vrid-1)# activate
When you configure a Backup router, the router interface on which you are configuring the VRID
must have a real IP address that is in the same subnet as the address associated with the VRID by
the Owner. However, the address cannot be the same.
Syntax: [no] ipv6 router vrrp
Syntax: [no] ipv6-address <ipv6-addr>
