lowered by the number specified in the track-port command. When the current priority is lower than
the threshold, the SPF behavior is temporarily suspended and reverts back to the pre-SPF VRRP-E
forwarding behavior. The value range is from 1 through 255.

Displaying short-path forwarding combinations

When short-path forwarding ( SPF) is configured, the output of the following show commands include
the SPF information:

show run
show ip vrrp-e brief
show ip vrrp-e vrid

The following example displays information about VRID 1 when only short-path forwarding is
configured.

device# show ip vrrp-e vrid 1

VRID 1

Interface ethernet v100

state backup

administrative-status enabled

priority 110

current priority 90

hello-interval 1000 msec

dead-interval 0 msec

current dead-interval 3500 msec

The following example displays information about VRID 1 when short-path forwarding and revert
priority are configured.

Suppressing default interface-level RA messages on an interface
configured with IPv6 VRRP or VRRP-E

By default, all IPv6-enabled interfaces send IPv6 Router Advertisement (RA) messages. If you
configure an IPv6 VRRP/VRRP-E instance on an interface, the VRRP or VRRP-E instance also sends
its IPv6 RA messages for the virtual IPv6 address on the same interface with the same source
address. An IPv6 host cannot identify the valid IPv6 address for this router interface because of these
two different IPv6 RA messages with the same source address from the same IPv6 router interface.
