1.0.0.0/8, auto-summary
1.1.1.0/24, cost 0, nexthop 1.1.1.1, RIP-interface
1.1.2.0/24, cost 0, nexthop 1.1.2.1, RIP-interface
1.1.3.0/24, cost 1, nexthop 1.1.1.2
1.1.4.0/24, cost 2, nexthop 1.1.1.2
1.1.5.0/24, cost 2, nexthop 1.1.1.2
The output shows that only one RIP route reaches network 1.1.5.0/24, with the next hop as Switch
B (1.1.1.2) and a cost of 2.

Network requirements
As shown in
932H
Figure 10 , Switch A and Switch B run OSPF, Switch D runs RIP, and Switch C runs OSPF and
RIP. Configure RIP to redistribute OSPF routes on Switch C so Switch D can learn routes destined for
networks 10.1.1.0/24, 10.2.1.0/24, 10.5.1.0/24, and 10.6.1.0/24.
To reduce the routing table size of Switch D, configure route summarization on Switch C to advertise only
the summary route 10.0.0.0/8 to Switch D.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic OSPF:
# Configure Switch A.
