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 two RIP routes destined for network 1.1.5.0/24. The next hops of the routes
are Switch B (1.1.1.2) and Switch C (1.1.2.2). The cost of the routes is 2.
3. Configure an additional metric for a RIP interface:
# Configure an inbound additional metric of 3 for RIP-enabled interface VLAN-interface 200 on
Switch A.
[SwitchA] interface vlan-interface 200
[SwitchA-Vlan-interface200] rip metricin 3
# Display all active routes in the RIP database on Switch A.
[SwitchA-Vlan-interface200] display rip 1 database

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.
RIP summary route advertisement configuration example
Network requirements
As shown in 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.
