I don't think you are tripping. I have been observing this too in few
ipexpert labs and I always keep any eye on this.

Subject: Gotcha on Redistribute Connected

Hi, all
Here is the layout where the "redistribute connected" got me.

R1-----ospf------R2-lo 0
                             |
                            rip
                             |
                            R3

What I did was that I redistributed the connected network (loopback
network)
into ospf with route-map only for the loopback network like this.
router ospf 1
 router-id 2.2.2.2
 log-adjacency-changes
 summary-address 170.100.20.0 255.255.255.0
 redistribute connected subnets route-map c2o
 redistribute rip subnets
 network 170.100.124.0 0.0.0.255 area 0
!
route-map c2o permit 10
 match ip address 1
!
access-list 1 permit 170.100.20.0 0.0.0.7

Now, I redistribute rip into ospf on R2.

The problem is that R1 can't see the rip network.

What I think is the gotcha is that when R2 redistribute "Connected" with
route-map, it filtered the rip network, because the rip network is the
connected network as well from the R2's stand point.

Am I saying right or I am tripping?

Please let me know what I am doing wrong here.

Thanks,

JP
