Is this an IPexpert lab?
If so which one is it?

Hi Steve,
Thanks a lot for replying, you are absolutly right on the first question as in
one of the Advance tech labs i attemted a question which asked the following
question
BB1--------R1
R1 is configured with RIPv2 and it;s is advertising its direectly connected
networks. Ensure that R1 gets 10 routes from BB1. Do not configure tunnel and
secondary IP.
The solution shows only one no validate source update on R1 and the routes are
transfered. to get reachabitly R1 is give a static route pointing towards the
seriel interface of BB1.
I consider this solution incomplete without mentionning the network statement
in BB1 or redistributing the routes in Rip. Please correct me if i am wrong.
Do you have an article which talks about suppressing null updates.
Regards
Piyush

I’m a little confused about your first question, maybe I’m not reading it right?
The “no validate update source” command tells RIP that it shouldn’t verify the
source IP address of the incoming routing updates, that’s it. If you want
routes to be advertised you will have to enable these networks underneath the
“router rip” command.
I’m pretty sure that the suppressing null update has something to do with split
horizon being enabled, can you post your RIP debug here?

Hi All,
I have 2 questions on RIP,
1) When i enable no validate source update on the router is it necessary to
enable it on the other end for e.g if two router R1 and R2 are peering and
running RIPv2, R1 has 10 loopbacks configured, can i get them propagted to R2
without including the network statement on R1. Can i do it by enabling no
validate source update?/????
2) When we debug ip rip events and we see suppressing null update , what does
that mean and what is the significance?
Hoping to hear from you.
Regards
