Hi,

No i'm not pinging directly from the switch or to the switch, as I know
PBR does not affect locally originated traffic... I'll try debug ip
policy...

Thanks

Tim

did the command "debug ip policy " help you to trobuleshoot ?
BTW ...I hope you are not trying to ping/traceroute directly from the
switch as you wld know this is local traffic and wont follow PBR unless
you specify local

ip route-caceh policy is just to make it fast switched rather than
process switched, even CEF is possible when you have the CEF turned on
along with PBR.

tunnel, <distribute list prevents it going to any other adjacency> but
the problem is I can't stop traffic from breaking away from the default,
ie, traffic from this one net, I want to send down the tunnel..

        How are you learning the route to 10.254.253.1?

        If it's directly attached (i.e. the local tunnel interface is
        10.254.253.2/30) then make sure your tunnel is in fact up.

        If it's unnumbered to a loopback, and the10.254.253.1 is on the
        loopback, look into how you're advertising that in your routing
        protocol(s).

        Have never tried this on a switch, but if the tunnel is
terminated on
        the switch, then here are a couple of suggestions:

        1. If you are trying to send all IP traffic down the tunnel,
then use a
        standard access-list.

        2. Instead of setting next-hop, set the interface to the tunnel
        interface.

        having said that without seeing the full config (and possibly
labbing
        it) I couldn't tell you why yours is not working.

        Hi Guys..<br><br>When you configure PBR on a SVI, does it behave

        normally?<br><br>Basically I've got a scenario where I need to
take some
