> Congestion control has been a very active area of discussion for other drafts. The congestion control text in the current version of draft-ietf-trill-over-ip was just copied with minor edits from an earlier version of draft-ietf-mpls-in-udp. That mpls draft has since been updated with substantial changes to its congestion section so I'm sure some work will be needed here.

Moreover, similar to draft-ietf-mpls-in-udp, I think it would be beneficial to add some brief text to clarify which case(s) in [RFC5405] that the draft-ietf-trill-over-ip belongs to, based on the specific features (if any) of Trill traffic.

I agree. RFC 5405 is a good reference to include.

Thanks,
Donald
