(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, reducing the routing table size of Switch D.
