7.42 BGP Conditional Route Injection - HELP!!!!!!

$
0

Community,
I'm stuck.  I have the correct configurations for 10.0.1.0/24, but I have a loop in my topology.  I know why the loop is there, what I don't know is how to fix it.  I've tried several things, such as AS prepending, but I get negative results. It seems that the inheritance aspect of the injected prefix is causing a loop between R4 and R5.  When I trace from BB3, I see the loop.  I completed the task, in terms of ensure the injected prefix is coming from R4, but it can't be right to have a loop in the topology.  Your help is greatly appreciated.
