Hi,
AFAIK, there are 3 ways to send a Summary Address from RIP
Say we have this basic RIP configuration
Sw2(config-router)#int lo 10
Sw2(config-if)#ip add 200.200.44.1 255.255.255.0
Sw2(config-if)#ip add 150.16.1.1 255.255.255.0 sec
Sw2(config-if)#ip add 1.1.25.1 255.255.255.0 sec
Sw2(config)#ip routing
Sw2(config)#router rip
Sw2(config-router)#version 2
Sw2(config-router)#passive-interface default
Sw2(config-router)#no passive-interface Vlan11
Sw2(config-router)#network 1.0.0.0
Sw2(config-router)#network 150.16.0.0
Sw2(config-router)#network 200.200.44.0
Sw2(config-router)#network 200.200.178.0
Sw2(config-router)#no auto-summary
By normal means Ver 2 will send this
1d04h: RIP: sending v2 flash update to 224.0.0.9 via Vlan11 (200.200.178.8)
1d04h: RIP: build flash update entries
1d04h: 1.1.25.0/24 via 0.0.0.0, metric 1, tag 0
1d04h: 150.16.1.0/24 via 0.0.0.0, metric 1, tag 0
1d04h: 200.200.44.0/24 via 0.0.0.0, metric 1, tag 0
1.- Send RIP Ver 1 Updates
interface Vlan11
ip address 200.200.178.8 255.255.255.0
ip rip send version 1
1d04h: RIP: sending v1 flash update to 255.255.255.255 via Vlan11
(200.200.178.8)
1d04h: RIP: build flash update entries
1d04h: network 1.0.0.0 metric 1
1d04h: network 150.16.0.0 metric 1
1d04h: network 200.200.44.0 metric 1
2.- Leave Auto-Summary Turn on
Sw2(config-if)#int vlan 11
Sw2(config-if)#no ip rip send ver 1
Sw2(config-if)#router rip
Sw2(config-router)#auto
Sw2(config-router)#do clear ip route *
Sw2(config-router)#
1d04h: RIP: sending request on Vlan11 to 224.0.0.9
1d04h: RIP: sending request on Vlan11 to 224.0.0.9
1d04h: RIP: sending request on Vlan11 to 224.0.0.9
1d04h: RIP: sending v2 flash update to 224.0.0.9 via Vlan11 (200.200.178.8)
1d04h: RIP: build flash update entries
1d04h: 1.0.0.0/8 via 0.0.0.0, metric 1, tag 0
1d04h: 150.16.0.0/16 via 0.0.0.0, metric 1, tag 0
1d04h: 200.200.44.0/24 via 0.0.0.0, metric 1, tag 0
And 3 the one you know- Ip Summary under the interface

Subject: About RIP SUMMARY
Hi everyone,
Without using command "ip summary-address rip x.x.x.x", how can I give a
summary address from one rip router to another rip router?
