    Hi All,

     

     

      Quick question.  I have a network where I use route tags to make import export descisions.  This works great as I tag the route when I export them from a VR and when I create a static route.  My question is is it possible to apply a tag to a directly connected route?

     

    I have a bunch of directly connected routes that get advertised into ospf and never leave the VR.  I would like those to have a tag when they are created.  Is this possible.

     

    Thanks

    As far as I know there isn't a tag attribute on direct/local routes as these are just logical interfaces within the RIB.  The Direct route will be the interface's IP/netmask and the Local route will be the interface's IP/32.

     

    You can however write a routing policy to export direct/local routes so that protocols such as RIP, OSPF, ISIS, etc can advertise and tag those prefixes to their neighbors.

    ..........Smiley Surprised  I didnt even think about that.  Thats the solution, I wont include the intereface in the ospf statement and just bring them in via a export policy.

     

    Thanks!
