Re: BGP Configuration Help

Hi Gabrielle,

Any special reason you make the interface IP address secondary? Also, what are you trying to accomplish with this static route?

ip route 0.0.0.0 255.255.255.255 10.1.1.0

I don't see your as-path access-list and route-map applied inside the BGP process.

Re: BGP Configuration Help

I am trying to help this customer get this up and running. I have another static that was for testing on the interface that is why it is secondary. Also, I am not sure why he has this route of 10.1.1.0.

Re: BGP Configuration Help

Hi Gabrielle,

You might have problem with the BGP peering section since the BGP peering will use the primary IP address. Beside that, this is the only issue I am seeing so far.

HTH,

jerry
