Hi Authors,
It seems that draft-rabadan-bess-evpn-inter-domain-opt-b has conflicting
discription with rfc7432 about the RD-type of AD per ES routes:
Section 3.1.3 of draft-rabadan-bess-evpn-inter-domain-opt-b-00: "If that is
the case, now the A-D per ES routes can use the route distinguisher assigned to
the EVPN Instance (or VRF), which is the same one used by the routes type 2 or
5 for the EVI."
Section 8.2.1 of rfc7432bis: "The Route Distinguisher MUST be a Type 1 RD
[RFC4364]. The value field comprises an IP address of the PE (typically, the
loopback address) followed by a number unique to the PE."
The RD of EVI is not always a Type 1 RD but rfc7432 says that the RD of AD per
ES route MUST be a Type1 RD. If it is not necessary to prevent other RD-types
from being used in AD per ES routes, is it better for rfc7432bis to change the
"MUST" to "MAY" ? I think such change is also compatible.
Thanks,
Yubao
