Re: Routing Context clarification

If the ASP is hosting/serving (what is the correct terminology?)
multiple AS'es, does it have to include the RC when it sending the
DATA to the SGP? My gut feeling is that the RC has to be included in
the DATA in both directions - ASP to SGP and SGP to ASP. Am I correct?

Cheers,
