[no] less-specific [allow-default]
config>vrrp>policy>priority-event>route-unknown prefix/mask-length
This command allows a CIDR shortest match hit on a route prefix that contains the IP route prefix
associated with the route unknown priority event.
The less-specific command modifies the search parameters for the IP route prefix specified in the
route-unknown priority event. Specifying less-specific allows a CIDR shortest match hit on a route
prefix that contains the IP route prefix.
The less-specific command eases the RTM lookup criteria when searching for the prefix/mask-length.
When the route-unknown priority event sends the prefix to the RTM (as if it was a destination
lookup), the result route table prefix (if a result is found) is checked to see if it is an exact match or a
less specific match. The less-specific command enables a less specific route table prefix to match the
configured prefix. When less-specific is not specified, a less specific route table prefix fails to match
the configured prefix. The allow-default optional parameter extends the less-specific match to
include the default route (0.0.0.0).
The no form of the command prevents RTM lookup results that are less specific than the route prefix
from matching.
no less-specific — The route unknown priority events requires an exact prefix/mask match.
allow-default — When the allow-default parameter is specified with the less-specific command, an
RTM return of 0.0.0.0 matches the IP prefix. If less-specific is entered without the allow-default
parameter, a return of 0.0.0.0 will not match the IP prefix. To disable allow-default, but continue
to allow less-specific match operation, only enter the less-specific command (without the allow-
default parameter).
[no] next-hop ip-address
config>vrrp>policy>priority-event>route-unknown prefix/mask-length
This command adds an allowed next hop IP address to match the IP route prefix for a route-unknown
priority control event.
If the next-hop IP address does not match one of the defined ip-address, the match is considered
unsuccessful and the route-unknown event transitions to the set state.
The next-hop command is optional. If no next-hop ip-address commands are configured, the
comparison between the RTM prefix return and the route-unknown IP route prefix are not included
in the next hop information.
