Re: OT - eBGP ISP route manipulation

Carlos,

You're right. i corrected my mistake in the inject-map and it works now..
 The last caveat is a I need to ensure anyone going to any other 1.x.x.x
take a different path, those users going to more specific routes would take
the eBGP ISP path .

Statics will work, but I'm trying to keep as my dynamic capability into it
as possible.
