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.

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, thus reducing the routing table size of Switch D.
