BGP distribution over RIP

[h4n0sh1]

Hi,

I'm trying to connect 2 ASN with a very basic BGP connection between R12 and R9.

I want to ping 10.0.0.9 from R14.

With my current setup i can ping R14 from R9 but not the opposite even though i've properly redistributed the BGP route learned from R12 into the 65002 RIP network.

R12 can ping 10.0.0.9 and here is it's bgp route :

Here you can see that the BGP route has been redistributed through RIP correctly :

And these are the routes for R14 :

Routes of R12 :

This is the result of a tcpdump on R14 when trying to ping 10.0.0.9 :

And the same with traceroute :

These are the packets received on R12 after the ping from R14 to 10.0.0.9 :

I really don't understand why i'm not able to ping R9 from R14 even though the route is shown, and the packet arrives to R12 but then they are not forwarded to R9 eventhough R12 knows how to reach it through BGP ...

Can somebody point me on what I am missing ?

Ok so I found the root of the issue.

R9 didn't know how to reach back to R14 because i forgot to redistribute RIP into BGP (the reverse).

This inside the conf of my 65002 ASN bgp router helped solve the issue:

redistribute rip metric <number>

Hello

Try to add the following and test again.

R12
router bgp xxx
neighbor <r14> next-hop-self
