The output shows that two RIP routes can reach network 1.1.5.0/24. Their next hops are Router A
(1.1.1.2) and Router B (1.1.2.2), respectively, with the same cost of 2. Router B is the next hop
router to reach network 1.1.4.0/24, with a cost of 1.
• Configure an additional metric of 3 for RIP-enabled GigabitEthernet 0/2 on LB.

The output shows that only one RIP route reaches network 1.1.5.0/24, with the next hop as Router
A (1.1.1.2) and a cost of 2.
Configuring RIP to advertise a summary route
1. Network requirements
As shown in Figure 125, Router A and Router B run OSPF; Router C ru
ns RIP; and LB runs OSPF and RIP.
Configure RIP to redistribute OSPF routes on LB so Router C can learn routes destined for networks
10 .1.1. 0 / 24 , 10 . 2 .1. 0 / 24 , 10 . 5 .1. 0 / 24 , a n d 10 . 6 .1. 0 / 24 .
To reduce the routing table size of Router C, configure route summarization on LB to advertise only the
summary route 10.0.0.0/8 to Router C.

• Configure IP addresses for interfaces. (Details not shown.)
