Yes, this is the only widely accepted way of doing this. Although in
IOS terminology it is referred to as summmarizaiton. (I know, I know
they are pretty much the same) I am not trying to start a semantics
war :)

Hi Robb
Depends on scenario.
You can use aggregation on AS2 and then that route will be seen as
originating from AS2.

If you strip off the AS path info what would you use for loop
detection. This is what BGP uses for loopfree routing.

there any way I can strip off the 3 (or everything else) in the
path to make it look like it originated in AS2?I know how to
prepend extra AS numbers on, but not delete them.BTW, anyone going
to San Jose 3/22 and 3/23?Thanks,Robb
