A is 206.186.134.1/24
B is 172.20.1.1/16
C is 172.20.20.1/16
This is what I have on the PM3:

The state keeps changing from Init, Loading, ExStart, and Full/DR, then
back to Init. Why is it not staying in Full. This makes the route
206.186.134.0 to go up and down.

What is the problem with the two?
Thanks in advance.
