Re: [trill] New Version Notification for draft-ietf-trill-irb-03.txt

Hi Donald,
Thanks for your detail suggestions. Will check and update it ASAP. As for the question in section 5.3:

[[[ I do not understand the paragraph above. How would RB1, say, learn the “IP Prefix” of IPv4 CE using ARP? ]]]
[weiguo]: My meaning is:  Because RB1 and RB2 are layer 3 gateway for CE1, RB1 and RB2 connect to CE1 through MC-LAG, so RB1 and RB2 will learn CE1's IP through ARP protocol. Then RB1 and RB2 announce the CE1's IP address to other RB to generate IP routing entries. Do you think the explanation is reasonable?

Thanks,
weiguo

Hi,

I did a pass over the document. See attached. Almost entirely
editorial / nits / typos suggestions but I did have one real question.
See my note on page 10, Section 5.3.

Thanks,
Donald
