Traffic shaping on a BGP session

["Pascal Petit - SYNET" <ppetit () synet fr>]

> 2 routers from 2 different AS are connected through 2 ATM virtual
circuits.

> EBGP Peering is set between  AS 1717 and 5511. 
> We would like to do traffic shaping on the incoming trafic on the two
> virtual circuits : All routes but a few shall be annouced via circuit 1;
> the remaining routes shall be annouced via circuit 2.

> We were planning on doing it via route-maps, however there is only one
BGP

static

> The former solution would be better while communities could be used to

> Questions :
> Is it possible to set up two BGP peerings between the same AS (i.e. two
BGP
> sessions between 1717 and 5511) ?
> Can one think of any better solution ?
