Re: [nvo3] [lisp] Comparing LISP multicast with draft-ghanwani-nvo3-app-mcast-framework-01.txt

Sharon,

Is the "floating anchor in mapping database" same as the "systemic
anchoring"?

Can you send me the draft names that describe the "floating anchoring"?  We
definitely should make it consistent across multiple WGs.

Thanks, Linda
