Hi Ankit, Thanks for your help. Assuming double exchange mode, IPSP-A should use routing context 1. By sending ASPAC, we are telling remote node that this ASP is ready to process traffic for a particular AS, and that AS is identified by supplied routing context. Then will SUA messages like CORE,COREF,CODT,RELRE etc will use Routing context= 2...?? because if this messages use routing-context=1 then it wont be possible to deliver it to the correct ASP in receving side. Please clarify if i m wrong, thanks.
