       1.1.5.0/24, cost 2, nexthop 1.1.2.2 

The display shows that there are two RIP routes to network 1.1.5.0/24. Their next hops are Switch B 

(1.1.1.2) and Switch C (1.1.2.2) respectively, with the same cost of 2. Switch C is the next hop router to 

reach network 1.1.4.0/24, with a cost of 1. 

3)  Configure an additional metric for the RIP interface. 

# Configure an additional metric of 3 for VLAN-interface 200 on Switch A.

       1.1.5.0/24, cost 2, nexthop 1.1.1.2 

The display shows that there is only one RIP route to network 1.1.5.0/24, with the next hop as Switch B 

(1.1.1.2) and a cost of 2. 

As shown in the following figure: 

z 

Switch A and Switch B run OSPF, Switch D runs RIP, and Switch C runs OSPF and RIP. 

z 

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. 

z 

Route summarization is configured on Switch C and only the summary route 10.0.0.0/8 is 

advertised, thus reducing the routing table size of Switch D.
