policy route route-map <map-name> rule <rule-num> match ip nexthop

Defines a match condition for a route map based on the next-hop address.

set policy route route-map map-name rule rule-num match ip nexthop { access-list list-num | prefix-list list-name }
delete policy route route-map map-name rule rule-num match ip nexthop
show policy route route-map map-name rule rule-num match ip nexthop

If no next-hop match condition is specified, packets are not filtered by next hop.

map-name
The name of a defined route map.
rule-num
The number of a defined route map rule.
access-list list-num
Matches the next-hop IP address in the route against those permitted by the specified access list. The access list must already be defined. Either access-list or prefix-list must be specified.
prefix-list list-name
Matches next-hop IP address in the route against those permitted by the specified prefix list. The prefix list must already be defined. Either access-list or prefix-list must be specified.

Configuration mode


policy {
    route-map map-name {
        rule rule-num {
            match {
                ip {
                    nexthop {
                        access-list list-num
                        prefix-list list-name
                    }
                }
            }
        }
    }
}

Use the set form of this command to define a match condition for a route map policy based on next-hop IP address.

Packets are matched based on whether the next-hop IP address of the route matches an address contained in the specified access list or prefix list. Depending on the action defined for the rule using policy route route-map <map-name> rule <rule-num> action, matched packets are either permitted or denied. Based on the forwarding information specified by the set statements in the route map rule, permitted packets are forwarded to their various destinations.

If more than one match condition is defined in a route map rule, the packet must match all conditions to count as a match. If no match condition is defined for the route map rule, all packets are considered to match the rule.

Use the delete form of this command to remove the next-hop IP address match condition.

Use the show form of this command to display next-hop IP address match condition configuration.
