ripv2 on cisco Cat6k-MSFC Version 12.1(1)E2

Hi,

What is the command to show which version of rip is running on the msfc?

Is ripv2 backward compatible with ripv1?

Are there any known problems withe rip and the

version of software we are running?

Thanks.

"sh ip prot" is the command.

Routing Protocol is "rip"

Sending updates every 30 seconds, next due in 1 seconds

Invalid after 180 seconds, hold down 180, flushed after 240

Outgoing update filter list for all interfaces is not set

Incoming update filter list for all interfaces is not set

Redistributing: rip

Default version control: send version 1, receive any version

Interface Send Recv Key-chain

Serial2/0 1 1 2

Routing for Networks:

192.168.12.0

Routing Information Sources:

By default, when you enable version 2 under router rip only version 2 messages are sent and received. You can use the "ip rip receive version 1 2" under specific interfaces to change that behavior.

Hope this helps,

Re: ripv2 on cisco Cat6k-MSFC Version 12.1(1)E2

Doesn't really help.

-Default version control: send version 1,

-receive any version

-Interface Send Recv Key-chain

Is this how you know if it's ripv2 or ripv1

What would cause a ripv2 to drop packets that

are ripv1?

If the receiver is ripv2, and receives ripv1,

will the routes be redistributed in v2 form?

- Looking at the information you provided, this device is running RIP version 1.

- If you enable RIPv2, by default only version 2 is sent and received. So V1 packets would be dropped.

If you enable RIPv2 and want to change the default behavior, you can go at the interface level and enter "ip rip receive 1 2". This will allow the RIPv2 router to receive and propagate the RIP V1 updates.

- The answer is yes. The RIPv1 routes will ve advertised as RIPv2 routes on all interfaces except on the one it has been received on.

Hope this helps,
