Hi everyone,

Regarding the draft:
https://datatracker.ietf.org/doc/draft-ietf-avtcore-ports-for-ucast-mcast-rtp/ 

During AUTH48, we discovered that the port parameter was optional in the following ABNF (section 7.1.1):

portmapping-req-attr = "a=portmapping-req" [":" port [SP nettype SP
addrtype SP connection-address]] CRLF

However, as it is clear from the text, port is essential for this attribute, while the address is still optional. So, we suggest to change the ABNF as follows:

portmapping-req-attr = "a=portmapping-req:" port [SP nettype SP
addrtype SP connection-address] CRLF

If you have any objection, now would be a good time to raise it.

Thanks.
