Hi Liyan,
I should replied to this Email rather than your request for an IETF 116 slot.
Please reply to this one.
I’m sorry but I don’t get this draft from a quick read. An OSPF router would
not advertise an adjacency until the router is in FULL state. An OSPF router
will not attain FULL state until database synchronization is complete.
The following statement from you use case is incorrect:
So, without requesting the starting router to update its LSAs, the
neighbors of the starting router may transition to "Full" state and
route the traffic through the starting router.
Why do you think you need this extension?
Thanks,
Acee
