Usage of route map (match interface)

[NaungHtunLwin0780]

Is there any useful case of “ match interface “ in route-map other than usage in NAT .
And I aslo want to know how “match interface”cmd  work . I mean , Does this command work for checking interface or mapping interface to appropriate route ?

Hi,

    Within a route-map, the "match" command is a condition, thus it works the same way, depending on what you use it for:

- if you use it for NAT, the "match interface" matches on the egress interface of the traffic

- if you use it for route-redistribution, the "match interface"matches on the prefix attached to the interface

Thank you very much. Your answer is very helpful for my complication . And I also want to know “ what is the different between MATCH INTERFACE and SET INTERFACE .

Hi,

   - "match" is a condition, examples specified in my first post

   - "set" is an action, one example of "set interface"  would be used in a route-map for the scope of PBR (policy-based routing), in order to force the packet egress out a specific interface and next-hop
