Slight miss communications, there really isnt a loop detection
in the on wire protocol, or multipath support, it simply excludes
certain routes that end up excluded by counting to infinity to
stop the loop (inifinity is usually 16 for this solution).
Its not like OSPF or BGP where you can calculate loops and mulipath effects.

Bottom line, RipV2 is not healthy on a network when loops exist,
though it should not lead to failure.

Yes.

I can not find any commit linked to that bug, but this is probalby before
the system to do that existed.  Unless we can confirm the bug still exists
I think it would be predunt to assume it is fixed based on what I read
in the PR, so dismissing the claim that the inbase routed "just glitches."

Can you agree with that logic Eugene?
