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.
device Router2(config)#router rip
device Router2(config-rip-router)#use-vrrp-path
Syntax: use-vrrp-path
The syntax is the same for VRRP and VRRP-E.
Hello interval
conguration
The Master periodically sends Hello messages to the Backup routers. The Backup routers use the Hello messages as verication that the
Master is still online. If the Backup routers stop receiving the Hello messages for the period of time specied 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
If the value for the dead interval is not congured, then the current dead interval is equal to three times the Hello interval plus the
Skew time (where Skew time is equal to (256 - priority) divided by 256). 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.
device Router1(config)#interface ethernet 1/1/6
device Router1(config-if-1/1/6)#ip vrrp vrid 1
device Router1(config-if-1/1/6-vrid-1)#hello-interval 10
Syntax: [no] hello-interval seconds
The seconds variable species the Hello interval value from 1 through 84 seconds for IPv4 VRRP, VRRP-E, and IPv6 VRRP-E and 1
through 40 seconds for IPv4 VRRPv3. The default is 1 second.
To change the Hello interval on the Master to 200 milliseconds for IPv6 VRRP, enter the following commands.
device Router1(config)# interface ethernet 1/1/6
device Router1(config-if-1/1/6)# ipv6 vrrp vrid 1
device Router1(config-if-1/1/6-vrid-1)# hello-interval 200
Syntax: [no] hello-interval milliseconds
The milliseconds variable can be 100 milliseconds interval only. The default is 1000 milliseconds, and the range is 100 to 40900
milliseconds.
To change the Hello interval on the Master to 200 milliseconds for IPv4 VRRPv3, enter the following commands.
Router1(config)# interface ethernet 1/1/6
Router1(config-if-1/1/6)# ipv6 vrrp vrid 1
Router1(config-if-1/1/6-vrid-1)# hello-interval msec 200
Syntax: [no] hello-interval msec milliseconds
IPv4 VRRPv2 supports the hello-interval
conguration in seconds, while IPv6 VRRP supports this conguration in milliseconds; both
use the CLI hello-interval xxx. However IPv4 VRRPv3 supports both the seconds and milliseconds conguration using the hello-
interval xxx and hello-interval msec xxx commands respectively.
