Configure route summarization:
# Configure route summarization on Switch C and advertise only the summary route 10.0.0.0/8.

[SwitchC-Vlan-interface300] rip summary-address 10.0.0.0 8

# Display the IP routing table on Switch D.

, VLAN-interface 100 of Switch A and Switch C runs RIP process 1. VLAN-interface

200 of Switch A runs RIP process 2. VLAN-interface 300 of Switch C and VLAN-interface 200 and

VLAN-interface 300 of Switch B run RIP process 1.
Configure a static route destined for 100.1.1.1/24 and enable static route redistribution into RIP on Switch

C so Switch A can learn two routes destined for 100.1.1.1/24 through VLAN-interface 100 and

VLAN-interface 200 respectively, and uses the one through VLAN-interface 100.
Enable BFD for RIP on VLAN-interface 100 of Switch A. When the link over VLAN-interface 100 fails,
BFD can quickly detect the failure and notify it to RIP so RIP deletes the neighbor relationship and route

information learned on VLAN-interface 100, and uses the route destined for 100.1.1.1 24 through

VLAN-interface 200.
