Re: I-D ACTION:draft-ietf-ospf-hitless-restart-06.txt

[Acee Lindem <[e-mail]>]

The only change in this version is that "hitless restart" has
been replaced by "graceful restart" (as per our discussion on
common graceful restart terminology between protocols). Due to
the respin on the draft, I'm extending the WG last call
period to February 21st, 2003. Please forward your
comments to the OSPF list before this time.

Thanks,
Acee
