Hi,
I have a question regarding Section 6.2.1 of 
7432bis<https://datatracker.ietf.org/doc/html/draft-ietf-bess-rfc7432bis-09#section-6.2.1>.

This section defines Port-based Service Interface in EVPN as "a special case of 
the VLAN bundle service interface, where all of the VLANs on the port are part 
of the same service and map to the same bundle" . It further states that "The 
procedures are identical to those described in Section 6.2" which, in its turn, 
says that "no VID translation is allowed for this (VLAN bundle - Sasha) service 
interface type".

My question is: what happens with untagged traffic received from an Ethernet 
port to which an EVI (or EVPN-VPWS) implementing port-based service interface 
is attached?
It seems that mapping untagged traffic to tagged using port-based VLAN ID at 
ingress and stripping this VLAN tag at egress is not compliant with the 
definitions above.

An interesting special case could be the case of an All-Active MH ES that runs 
LACP on its constituent links vs. the attached CE.

Your feedback would be highly appreciated.

Regards, and lots of thanks in advance,
Sasha
