Configure an RIP Route Summary

Network Requirements

RIPv2 runs between Device1, Device2, Device3, and Device4 for route interaction.
Device1 learns two routes 100.1.0.0/24 and 100.2.0.0/24 from Device2. To reduce the size of the routing table of Device1, it is required that Device advertises only the route summary of the two routes to Device1.

Networking for Configuring RIP Route Summary

Figure 5-5 Networking for Configuring RIP Route Summary

Configuration Steps

Step 1: Create VLANs, and add ports to the required VLANs. (Omitted)

Step 2: Configure IP addresses for the ports. (Omitted)

Step 3: Configure RIP.

#Configure Device1.

Device1#configure terminal
Device1(config)#router rip
Device1(config-rip)#version 2
Device1(config-rip)#network 1.0.0.0
Device1(config-rip)#exit

#Configure Device2.

Device2#configure terminal
Device2(config)#router rip
Device2(config-rip)#version 2
Device2(config-rip)#network 1.0.0.0
Device2(config-rip)#network 2.0.0.0
Device2(config-rip)#network 3.0.0.0
Device2(config-rip)#exit

#Configure Device3.

Device3#configure terminal
Device3(config)#router rip
Device3(config-rip)#version 2
Device3(config-rip)#network 2.0.0.0
Device3(config-rip)#network 100.0.0.0
Device3(config-rip)#exit

#Configure Device4.

Device4#configure terminal
Device4(config)#router rip
Device4(config-rip)#version 2
Device4(config-rip)#network 3.0.0.0
Device4(config-rip)#network 100.0.0.0
Device4(config-rip)#exit

#Query the routing table of Device1.

Device1#show ip route 
Codes: C - Connected, L - Local, S - static, R - RIP, B - BGP, i-ISIS 
       U - Per-user Static route 
       O - OSPF, OE-OSPF External, M - Management, E - IRMP, EX - IRMP external 
 
C 1.0.0.0/24 is directly connected, 00:23:06, vlan2 
R 2.0.0.0/24 [120/1] via 1.0.0.2, 00:13:26, vlan2
R 3.0.0.0/24 [120/1] via 1.0.0.2, 00:13:26, vlan2
R 100.1.0.0/24 [120/2] via 1.0.0.2, 00:08:31, vlan2
R 100.2.0.0/24 [120/2] via 1.0.0.2, 00:08:31, vlan2
C 127.0.0.0/8 is directly connected, 76:51:00, lo0

Step 4: Configure a summary of routes on an interface.

#On Device2, configure a route summary 100.0.0.0/8.

Device2(config)#interface vlan2
Device2(config-if-vlan2)#ip summary-address rip 100.0.0.0/8
Device2(config-if-vlan2)#exit

Step 5: Check the result.
