As5300 routing

Can anyone tell me why this setup on a As5300 (router rip

version 2

network 133.94.0.0)

would advertise its routes as a /32 to each dial in IP address?

And does the As5300 even need to be routing IPs ?

TIA

I believe that you will find that the 5300 is putting /32 host routes into the routing table because of the ppp negotiation where the 5300 is assigning addresses out of a dial pool. It needs those entries to keep track of which device/async is using which address.

I have had similar exeriences with configuring dial access and was able to generate a summary route which included all the individual /32 routes.

As to whether the 5300 needs to be routing IPs depends on how you want things to work. You have set up the 5300 to run a dynamic routing protocol which allows it to announce to the rest of the network the IP addresses it can reach. If you do not want it to run a dynamic routing protocol I believe that it should be possible to configure the 5300 with a default route pointing to the next hop over its LAN interface to support outbound traffic. And it should be possible to configure a static route on its neighbor router for the addresses in the dial pool. If you do this the 5300 probably does not need to run a dynamic routing protocol.
