Right. They wont be in the routing table because you are doing PBR.
The RIB (routing table) is what will take over by default if the policy
route is not working.

Try what I suggested and see what happens.

        the way i was verifying it was by looking at the routes in the
routing table.............and they were not pointing to the right
next-hop address...

RE: policy routing

        Your configuration looks right to me. You might be having
problems
        because of the way you are trying to verify it is working.

        Try setting a loopback on R1 and do an extended ping from the
loopback
        as the source and a 1.1.1.0/24 or 2.2.2.0/24 address while doing
a
        "debug ip policy"

        Your output should show you that the policy is being matched and
routed
        out the appropriate interface. If not, it will say it is NOT
being
        policy routed.

        HTH,

        Andy

        Subject: policy routing

        here is what i'm trying to do.......perhaps it's not possible,
perhaps
        so....

r1----------------------------------r2---------------------------------r
        4------------bb
        -
        -
        -
        -

------------------------------------r3----------------------------------

        r1 is connected to both r2 and r3 which also both have
connection to r4,
        so
        r1 had 2 paths to r4, via r2 and r3.

        r4 is receivin prefixes from the bb router. 1.1.1.0/24 and
2.2.2.0/24.
        i want r1 to route thru r2 for 1.1.1.0.24 and thru r3 for
2.2.2.0/24.

        is policy routing possible for this?
        i tiried the following <please excuse is the syntax is off since
i don't

        have a router in front of me>

        r1 <cfg>ip local policy route-map policy
                   route-map policy permit 10
                   match ip add prefix 5
                   set ip next-hop r2
                   route-map policy permit 20
                   match ip add pre 6
                   set ip next-hop r3

                   ip prefix-l 5 permit 1.1.1.0/24
                   ip prefix-l 6 permit 2.2.2.0/24

                   ip cef
                   int s0/0
                   no ip route-cache

        am i way off here? i just could not get it to work, even tho
there were

        matches to my route-map and prefix list. i also tried an
access-l
        instead
        but no dice.
        any thoughts?
