Re: [trill] draft-ietf-trill-transport-over-mpls

Sue,

I found that this draft has several places where interoperability between
implementations could be difficult because there are several implementation
choices that can be made, and the draft doesn’t make any particular
recommendations or require any of the choices to be implemented.

1. There are two models defined, the VPLS and VPTS models, and the draft
doesn’t recommend which to use for each of the two problem statements. If
it were me, I would recommend the VPTS model as the default, as it is an
emulated TRILL service.

2. When using the VPTS model, section 4.3 says that either the PPP or
Ethernet encapsulation from RFC 7173 can be used, and makes no
recommendation between them. However, RFC 7173 defines the PPP
encapsulation as the chosen default, and that encapsulation should be used
here as well.

I recommend that these be addressed before the draft is sent to the IESG.

Thanks,
Andy
