Overview: Odl is configured with ll-graceful-restart, we connect peer to it with one route, and disconnect it. After graceful-restart-timer (5s in this case) runs out, an error in karaf logs pops up, and play.py is unable to connect again.

Steps to reproduce
Configure odl with ll-graceful-restart (one peer, ipv4 only)

./configure.py

Connect peer

./start_play1.py

Kill play.py

Ctrl+c

Wait 5 seconds and see karaf.log

At this point we wanted to start different play.py on different ip, so we would get advertisement from odl with route containing ll-graceful-restart community.

to do this ->

./start_play3.py
