I can't believe I just did this.... I just sent a very long reply based on the fact that I didn't even read through the entire config!! geez...I'm really embarrassed.... Here I think I'm explaining iBGP meshes, etc. to this guy and now after reading Curtis' response I see that he already had route reflectors configured! Oh man.... time to go watch some more of the Rockies/Diamondbacks game. The Rocks are losing but I don't care. I don't want to do more damage here tonight! ;-) Regards, John the Incomplete Reader | I don't believe it's legal to change the next hop when you are reflecting | routes.
