Re: [Pals] I-D Action: draft-cheng-pals-p2p-pw-multicast-01.txt

Weiqiang and Jie,

I would suggest adding references to the BBF documents and limiting this
draft to what's not already covered there, and using the Independent Stream
to publish this as an implementation note for operators. I've copied the
ISE for his comments as well.

Cheers,
Andy
