It depends on specific technology, e.g., if PCP is used, AFTR does not keep the state of which B4s it is speaking to . But if some bidirectional technology is used, e.g., BFD, AFTR will keep the state. > > 2. It's fairly clear how BFD session can be instantiated/maintained on B4 (to > AFTR).

BFD sessions could be sent from AFTR only after B4 firstly initiated the session. So the answer is that this is configured. > > -Nobo > > _______________________________________________ > Softwires mailing list > [email protected] > https://www.ietf.org/mailman/listinfo/softwires _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
