Use this command to identify a route map to use for policy-based routing on an interface specified by route-map-name. Policy-based routing is configured on the interface that receives the packets, not on the interface from which the packets are sent.
When a route-map applied on the interface is changed, that is, if new statements are added to the route-map or match/set terms are added to or removed from the route-map statement, and also if the route-map that is applied on an interface is removed, the route-map needs to be removed from the interface and added back again in order for the changed route-map configuration to take effect.
A route-map statement should contain eligible match/set conditions for policy-based routing in order to be applied to hardware.
- Valid match conditions: match ip address acl, match mac-list, match length
- Valid set conditions: set ip next-hop, set ip default next-hop, set ip precedence
A route-map statement should contain at least one match condition and one set condition as specified above for it to be eligible to be applied to hardware. If not, the route-map is not applied to hardware.
When a route-map is applied on a VLAN interface and a DiffServ policy is applied on a member port of the same VLAN interface, the port policy takes priority over the VLAN policy.
Route-map and DiffServ cannot work on the same interface.
| Format | ip policy route-map-name |
| Mode | Interface Config |
Example: The following is an example of this command.
(Routing) (Config)#interface 1/0/1 (Routing) (Interface 1/0/1)# (Switching) (Interface 1/0/1)# #ip policy route-map equal-access
To disable policy based routing from an interface, use the no form of this command:
no ip policy route-map route-map-name
When a route-map has both IPv4 and IPv6 statements provisioned and the user applies the route-map using IP policy command, the IPv6 statements in the route-map will not take effect. A message will be displayed to the user to indicate this.
Example:
(Routing) (Interface vlan 40)#ip policy route-map rm4
IPv6 statements in this route-map will not be applied using IPv4 Policy Based Routing.
