Hi Group
I'm having an issue with local-as in BGP.
r2
|
|
r5
R2 and R5 are connected via a serial p2p which has layer 3 connectivity. I basically trying to get r2 to form adj with r5 using a local-as of 5 instead of as 5678. I have done this before without any problems. I cannot seem to find the fault.
TIA
Mark
