hi all,
I have a question regarding announcement of routes via
BGP.
Well we are an INTERNET BACKBONE FOR our customers who
are ISPs .
As a result we have many upstream providers like AT&T
, ABOVENET etc.
Recently our customers just have this new network
blocks namely 146.222.185.0 /24, 146.2
Hmmm.. Looks like somobody inject this routes into IGP
and does auto-summary at him exiting router.

You send several /24 routes, your upstream :
- 1st choice: upstream doing atomic agregation
- 2nd: upstream insert into IGP->.IGP->BGP with auto-summary thats
default->at ATT You see class B net.
By the way the ASpath is right?

1. In global Internet operations, no one should do auto-summary.
Summarization needs to be planned.
2. It is rarely
