Hi,

 

I have a situation as follows:

C1 --- P1 --- P2 --- P3 --- ISP1 --- ISP2

 

All routers have eBGP peer relationship were C1 holds public AS, P1 to
P3
holds private AS (each) and ISP1 is my edge router with my public AS.

Configuring remove-private-as on ISP1 wouldn't remove the private-as as
it
will see it a configuration error due to public-private-public sequence.

Is there any other way to remove the private AS and preserve the AS-Path
with only public?

 

Best Regards,

Techtalm
