Hi, I agree that we should say that BUNDLE multiplexing is not supported in this specification, and that BFCP m- lines MUST NOT be included in a bundle group. Perhaps you could put that text in a small “BUNDLE Considerations” chapter, or something similar? Regarding where to define the MUX category for the new attribute, I suggest we do it in this draft, since that is part of the information you need to specify when registering a new attribute. Regarding the mux category value, I guess IDENTICAL would work – eventhough it’s a little strange considering we don’t define BFCP multiplexing to begin with. Would TBD be more suitable?

Hopefully, the authors of draft-ietf-mmusic-sdp-mux-attributes will add them to this draft. I do like to move the BUNDLE reference to informational, so I support Charles' text proposal in his last paragraph below. -- Tom ________________________________ Fra: Charles Eckel (eckelcu) Sendt: 8. juli 2016 23:39 Til: Tom Kristensen; bfcpbis@ietf.org<mailto:bfcpbis@ietf.org> Kopi: Tom Kristensen (tomkrist); Suhas Nandakumar (snandaku); Christer Holmberg Emne: Re: [bfcpbis] I-D Action: draft-ietf-bfcpbis-rfc4583bis-15.txt Hi Tom, Thanks for incorporating the changes. The dtls-id change looks good. Unfortunately, the MUX category change suffers from the fact we are chasing a moving target. draft-ietf-mmusic-sdp-mux-attributes was updated recently and the NOT RECOMMENDED category was replaced with the CAUTION category. Upon taking another look at draft-ietf-mmusic-sdp-mux-attributes, my previous suggestion was not good. draft-ietf-mmusic-sdp-mux-attributes already defines the Mux category for all SDP attribute defined in rfc4583bis except the newly added bfcpver SDP attribute. For this, I think the Mux category should be IDENTICAL. However, I’m not sure if it should be added to rfc4583bis or to draft-ietf-mmusic-sdp-mux-attributes directly. I have cc’d Suhas to Christer to get their input, both on the mux category selected and where it should be specified. As for multiplexing of BFCP lines, perhaps rfc4583bis should simply say, "Multiplexing of BFCP ‘m' lines, as defined in BUNDLE [16], is not defined by this specification.” If we agree to this, the reference to BUNDLE should be Informational instead of Normative.
