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.
Configuring RIP to advertise a summary route
Network requirements
As shown in the following figure:
• 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 that Switch D has 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.
• Route summarization is configured on Switch C and only the summary route 10.0.0.0/8 is
advertised, reducing the routing table size of Switch D.
