It is important for identifier such as M-ID with local significance rather than global ones , especially for exchanges occur simultaneously among multiple connections. To use message ID with local significance in phase two of IKE(similar to tunnel establishment in L2TP): 1) If Alice chooses X1 as the Initiator M-ID when initiating an exchange to Bob, Alice should set M-ID in HDR to zero and attach a payload to indicate X1 as initiator's M-ID for subsequent messages from Bob to Alice. 2) Then Bob sets M-ID in HDR to X1 as response to Alice, and also attaches a payload to indicate Y1 as responder's M-ID for subsequent messages from Alice to Bob. 3) Now for messages followed within this exchange, if A->B, set M-ID to Y1; if B->A, set M-ID to X1.
