I've just done question 2 for you.

ROUTER1
router rip
 version 1
 network 130.9.0.0 this is on the subnet between router 1&2
 no auto-summary
!

ROUTER2
router rip
 version 1
 no auto-summary
 redistribute ospf 4000 metric 10 !this gets your route x.x.x.x into rip
(use route map in practice)
 network 130.9.0.0
 default-information originate route-map my_route_map
 distribute-list prefix rip_prefix out
!
route-map my_route_map permit 10
 match ip address prefix-list my_ospf_prefix
!
ip prefix-list my_ospf_prefix seq 5 permit 130.8.5.0/24 - this is the route
x.x.x.x you are looking for!!!!!
!
ip prefix-list rip_prefix seq 20 permit 130.8.0.0/16
ip prefix-list rip_prefix seq 20 permit 0.0.0.0/0 - these are the rip
updates you allow to router 1
in this case just the default

this is the rip database on router 1

Router1#show ip rip database
0.0.0.0/0
    [1] via 130.9.1.2, 00:00:12, Ethernet0
130.8.0.0/16 auto-summary
130.8.0.0/16
    [10] via 130.9.1.2, 00:00:12, Ethernet0
130.9.0.0/16 auto-summary
130.9.1.0/24 directly connected, Ethernet0
130.9.2.0/24 directly connected, Loopback1
130.9.3.0/24 directly connected, Loopback2
130.9.4.0/24 directly connected, Loopback3

Router1#show ip route rip
R 130.8.0.0/16 [120/10] via 130.9.1.2, 00:00:08, Ethernet0
R* 0.0.0.0/0 [120/1] via 130.9.1.2, 00:00:08, Ethernet0
Router1#

in my experience RIP is paticularly bad at NOT auto-summering!

hope this helps

Adam

Subject: EIGRP Query and RIP default route

I have two quick questions:

1. In EIGRP, how do I configure a router not to query for routes that are
not directly attached to its neighbor?

2. If R1 and R2 is running RIP v1 between them, and R2 is also running
OSPF, how do I configure R2 to provide a default route for R1, as long as
R2 learns about a route x.x.x.x?

Thanks in advance.
