Re: BGP Aggregate AS-Path Prepend

R2(AS1)-------R3(AS2)

R1 sends R2 150.2.2.0/24. In R2, I'm creating the aggregate 150.2.0.0/16.
I'm trying to manually set the as-path of the aggregate route. That is, I
don't want to use the as-set key work, rather a route-map with the as
prepend set feature.

 Here is the command:

  aggregate-address 150.2.0.0 255.255.0.0 attribute-map prepend

 route-map prepend permit 10
 set as-path prepend 1

I keep getting the same error.

Thanks,

Yasser

What is the exact command you are trying to issue? Could you paste your
config?

Is it possible to prepend an AS path to a locally originated aggregate
route? What I'm trying to do is manually retain the as path without using
the as-set keyword.

I keep getting the following error when using a route/attribute map with the
aggregate-address command:

% "prepend" used as BGP attribute route-map, set as-path prepend not
supported

Many Thanks,

Yasser
