1.1.5.0/24, cost 2, nexthop 1.1.1.2
1.1.5.0/24, cost 2, nexthop 1.1.2.2
The output shows that two RIP routes can reach network 1.1.5.0/24. Their next hops are Router B
(1.1.1.2) and Router C (1.1.2.2) respectively, with the same cost of 2. Router 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 GigabitEthernet 0/2 on Firewall.
[Firewall] interface GigabitEthernet 0/2

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 Router
B (1.1.1.2) and a cost of 2.
Configuring RIP to advertise a summary route at the CLI
Network requirements
As shown in Figure 246, Router A and Router B run OSPF, Router C runs RIP, and Firewall runs OSPF and
RIP.
Configure RIP to redistribute OSPF routes on Firewall so that Router C has 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 .
Configure route summarization on Firewall to make it advertise only the summary route 10.0.0.0/8,
reducing the routing table size of Router C.
