I am seeking some feedback/help with my BGP configuration. I am peering =
with two providers level3 and tw. Unfortunately all of my address =
spaces are preferring the route over tw rather than level3. I have =
tried Prepending my AS and the carriers AS to the path on the tw side =
and I see those update being accepted by internet routers, but everyone =
is still preferring to install the tw routes rather than level3. I was =
trying to advertise each provider's address space out their connections =
and then use the other for backup. Now however everything is coming in =
through tw and no one seems to like level3.
Thanks in advance for any guidance or assistance.
Joe
