bird rip question

[Miklós Máté]

Hi,

I'm trying to set up BIRD to demonstrate RIP in a Mininet environment, 
but it doesn't seem to work. I'm using the attached configs. The OSPF 
one works properly, but with RIP it only sends a Request message on 
startup, and then nothing. According to the log the Request is received 
properly, but no Response is sent, and the periodic timer doesn't do 
anything either.

This is the stderr log on node B when I start BIRD on the neighboring 
node A:

2023-10-06 15:50:03.951 <TRACE> rip1: New neighbor 10.0.1.1 on ethBA
2023-10-06 15:50:03.951 <TRACE> rip1: Request received from 10.0.1.1 on

2023-10-06 15:50:22.453 <TRACE> rip1: Sending regular updates for ethBC

I'm completely out of ideas. The sample configs don't have anything that 
is not in my config. What am I missing?
