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. as all other sua messages from IPSP-A to IPSB-B will use routing context of > 2, so wil it be used in ASP ACTIVE? > No > > Also...in ASP ACTIVE ACK message the routing context recevied in ASP > ACTIVE should be sent back? > Yes, because if IPSP-A wants to handle traffic for more than one AS then it could send ASPAC messages(with respective routing contexts) for all of them.
