AFIAK 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

 

router rip

 version 2

 passive-interface default

 no passive-interface Vlan11

 network 1.0.0.0

 network 150.16.0.0

 network 200.200.44.0

 network 200.200.178.0

 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

Sw2(config-router)#

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.

 

I'm CC the Group, so see if there are any other ways

Regards

Group,

One of task say send out 155.155.0.0/16 ( aggregate) with metric 4 and
166.166.1.0/24 <http://166.166.1.0/24> with metrci 3.

I tried to use offset-list but can't achieve the desired result. I was
thinking to use route-map with distribute list but it seems route-map is not
supported with distribute list in RIP.

How can I achieve this ?

Thanks
