RIP: ignored v2 update from bad source

If you receive the following message when configuring two cisco routers to share routes via RIP v2:

RIP: ignored v2 update from bad source 192.168.1.1

Run the no validate-update-source on your rip configuration and the updates will start to work.

router rip
no validate-update-source

    Also both routers could be in a different subnet,
    R1 10.0.0.1/24 —– r2 10.0.0.2/25

    Yes Paco, mostly you encouter this problem because of wrong ip/subnet.
