Re: Validate Update source command - RIP

In this case how did you configure your static route. Does it points to
the nexthop ip or the outgoing interface?

R1-----e0/0-------------------------------------------e0/1----BB1
            1.1.1.1/24
2.2.2.2/24
In this scenario you need to use two static routes as below

R1
  ip route 2.2.2.2 255.255.255.255 e0/0

BB1
  ip route 1.1.1.1 255.255.255.255 e0/1

not only the above, you need to configure no validate-update-source on
both R1 and BB1.

Then you should receive all the rip routes from BB1 --> R1 and R1--->BB1.
So no matter how many routers connected to R1, they should be able to
reach BB1 connected interfaces if all are advertised by rip.
