It was just a question. When a peer sends an update of locally
originated routes, if it is to a peer in the same AS then it sends the
ASPATH with a value of 0. If it is a peer in another AS then it adds his
own AS number.
Thus my question, is having a value of 0 adding or modifying ?

But when not set, is an attribute empty or missing ?

Hi Yasser,
The attribute map command is to manipulate the BGP attributes,that is
what I believe,so you can modify any BGP attributes,but cant add any
more attributes,pls correct if iam wrong. Thanks Mohamed.

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?

Subject: BGP Aggregate AS-Path Prepend
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
