Hi Authors,
In <draft-ietf-bess-dci-evpn-overlay>, there isn't any reference to RFC7543
(2015) before its revision 09 (2018.2).
But the UMR format in this draft is a bit different from RFC7543 almost from
its beginning revision.
The difference is in the MAC Address Length field.
In this draft, it should be 48 from its beginning revision.
But in RF7543, it should be 0.
Before the revision 09, I think it is no doubt that the MAC Address Length
should be set to 48.
But after the revision 09, although RFC7543 is referred, it also says that the
MAC Address Length should be 48 at the same time.
The details can be found at:
https://tools.ietf.org/rfcdiff?url2=draft-ietf-bess-dci-evpn-overlay-09.txt
So when a UMR is advertised, which value should the MAC Address Length be set
to?
Thanks,
Bob
