Additional VRRP and VRRP-E parameter configuration
Suppressing RIP advertisements for the backed-up
interface in Router 2
To suppress RIP advertisements for the backed-up interface in Router 2, enter the following
commands.
Brocade Router2(config)#router rip
Brocade Router2(config-rip-router)#use-vrrp-path
Syntax: use-vrrp-path
The syntax is the same for VRRP and VRRP-E.
Hello interval configuration
The Master periodically sends Hello messages to the Backup routers. The Backup routers use the
Hello messages as verification that the Master is still online. If the Backup routers stop receiving
the Hello messages for the period of time specified by the dead interval, the Backup routers
determine that the Master router is dead. At this point, the Backup router with the highest priority
becomes the new Master router.
NOTE
The default dead interval is three times the Hello interval plus the Skew time. Generally, if you
change the Hello interval, you also should change the dead interval on the Backup routers.
To change the Hello interval on the Master to 10 seconds, enter the following commands.
Brocade Router1(config)#interface ethernet 1/1/6
Brocade Router1(config-if-e10000-1/1/6)#ip vrrp vrid 1
Brocade Router1(config-if-e10000-1/1/6-vrid-1)#hello-interval 10
Syntax: [no] hello-interval seconds
The seconds variable specifies the Hello interval value from 1 through 84 seconds for VRRP v2,
VRRP-E v2, and IPv6 VRRP-E. The default is 1 second.
To change the Hello interval on the Master to 200 milliseconds for IPv6 VRRP v3, enter the
following commands.
Brocade Router1(config)# interface ethernet 1/1/6
Brocade Router1(config-if-e10000-1/1/6)# ipv6 vrrp vrid 1
Brocade Router1(config-if-e10000-1/1/6-vrid-1)# hello-interval 200
Syntax: [no] hello-interval milliseconds
The milliseconds variable can be from 100 through 8400 milliseconds. The default is 1000
milliseconds.
