Additional VRRP and VRRP-E parameter configuration
Configuring an IPv6 VRRP v3 interface as a Backup for a VRID
To configure an IPv6 VRRP v3 interface as a Backup for a VRID, and set its VRRP priority and track
priority, enter commands such as the following.
Brocade Router2(config)# interface ethernet 1/5
Brocade Router2(config-if-e10000-1/1)# ipv6 vrrp vrid 1
Brocade Router2(config-if-e10000-1/1-vrid-1)# backup priority 50 track-priority
10
Brocade Router2(config-if-1/1-vrid-1)#advertise backup
Configuring an IPv6 VRRP-E v3 interface as a Backup for a VRID
To configure an IPv6 VRRP-E v3 interface as a Backup for a VRID, and set its VRRP-E priority and
track priority, enter commands such as the following.
Brocade Router2(config)#interface ethernet 1/1
Brocade Router2(config-if-1/1)#ipv6 vrrp-extended vrid 1
Brocade Router2(config-if-1/1-vrid-1)#backup priority 50 track-priority 10
Brocade Router2(config-if-1/1-vrid-1)#advertise backup
VRRP v2 and IPv6 VRRP v3 syntax
Syntax: owner [track-priority <value>]
The track-priority <value> option changes the track port priority for this interface and VRID from the
default (2) to a value from 1 through 254.
Syntax: backup [priority <value>] [track-priority <value>]
The priority <value> option specifies the VRRP priority for this interface and VRID. You can specify
a value from 3 through 254. The default is 100.
The track-priority <value> option is the same as with the owner [track-priority <value>] command.
VRRP-E v2 and IPv6 VRRP-E v3 syntax
Syntax: backup [priority <value>] [track-priority <value>]
The software requires you to identify a VRRP-E interface as a Backup for its VRID before you can
activate the interface for the VRID. However, after you configure the VRID, you can use this
command to change its priority or track priority. The option values are the same as for VRRP.
Suppression of RIP advertisements
NOTE
Suppression of RIPng advertisements on Backup routers for the backup interface is not supported
by IPv6 VRRP v3 and IPv6 VRRP-E v3.
Normally, a VRRP or VRRP-E Backup includes route information for the virtual IP address (the
backed-up interface) in RIP advertisements. As a result, other routers receive multiple paths for
the backed-up interface and might sometimes unsuccessfully use the path to the Backup router
rather than the path to the Master.
You can prevent the Backup routers from advertising route information for the backed-up interface
by enabling suppression of the advertisements.
