[j-nsp] Routing-instances with different AS'es

[Alexander Arsenyev (GU/ETL)]

Hello Jonas,
Have You actually had a look into the webpage? It describes a feature
called "local-as" where single router can be viewed from outside "AS IF"
it belongs to more than 1 AS. 
Pedro suggested another way of doing this with routing instances of type
"virtual-router" but it is essentially the same as "local-as" when
viewed from outside...
HTH
Cheers
Alex

Hi Alex,

this is not was i am looking for. I need to have 2 AS'es (or even more)
one the *same* router, not different ones. 
E.g. in general the router should have AS65000 and another
routing-instance with AS65001. This routing instance should then
import/get the routes from AS65000 and announce a specific route to
AS65000.
To sum it up: I want to have an announcement (going out to the net) of a
prefix which then should have an as-path of 65000 65001.


Regards,
Jonas
