Hi,
What is the exact subnet mask of your connected loopback addresses as
listed in the routing table? The prefix-list as you've configured in
option B must also make an EXACT 21-bit match on the SUBNET MASK also.
That is the beauty of prefix-lists - that they are more granular in that
they look at the subnet mask in addition to the network address.
If your subnet mask on your loopback interface are /24's, then I would
suggest using:
ip prefix-list NEW permit 111.1.0.0/24
HTH,
Curt

Subject: Prefix-list RIP and redistribution
Hello guys!
lo - R1 - R2 -lo
I have rip configured between R1 and R2. I also configured some
loopbacks interfaces on R1 with IP addresses of: 111.1.x.0
(x=1,2,3,4,5,6,7). I want redistribute this directly connected
interfaces into RIP so that R2 has the route to it.
I configure: router rip
redistribute connected metric 2 route-map NEWCONNECTED:
Question:
If I use configuration A everything works just fine:
A:
access-list 2 permit 111.1.0.0 0.0.7.255 route-map NEWCONNECTED permit
10 match ip address 2
But if I use configuration B nothig is redistributed, and R2 doesn't see
any routes from R1:
b:
ip prefix-list NEW permit 111.1.0.0/21
route-map NEWCONNECTED permit 10
match ip address prefix-list NEW.
Why ip prefix-list doesn't match this routes. I just can't understand
what is ther reason of such behaviour. Could anybody please explain.
Thanks,
