Hi Acee,

	>Note that the local application use case ties nicely to the transport instance draft (https://tools.ietf.org/id/draft-ietf-ospf-transport-instance-11.txt)
	> Specifically, with the remote-neighbor capability, one can use an instance only including the nodes running the local application and requiring

We have presented this point in earlier meetings. 

" It’s reasonable that non-routing information should be advertised in a non-routing instance of OSPF as defined in https://tools.ietf.org/html/draft-ietf-ospf-transport-instance-11 so as to minimize the impact on the operation of routing."

"However, since the information contained in the Operator Defined TLV may be related to the routing, whether or not using a non-routing  instance to flood the OD TLVs should be determined by operators according to the information to be conveyed by the OD  sub-TLV."

Thx!
