RE: policy routing

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?
