hi russ, couple of comments / questions.
1) --- OpenFabric implementations MUST NOT be mixed with standard IS-IS implementations in operational deployments. OpenFabric and standard IS-IS implementations SHOULD be treated as two separate protocols. --- any hard feelings about using MI as a way of guaranteeing that the two protocols are shielded from each other ? 2) Modified Adjacency Formation rather than doing the "only one adjacency is up" (which we did prior to the graceful-restart SA bit) - suggest to use the graceful-restart 'SA' bit, such that a node can bring up the adjacency without generating a new LSP. The LSP can then be generated if the initial-sync is done (and the new LSP arrival rate indicates that the dust is settling) such that the LSP may get released. 3) Flooding Optimization it looks to me you have re-invented the OLSR MPR set. https://tools.ietf.org/html/rfc3626#section-8.2 perhaps you may want to add a reference. /hannes On 3/7/17 3:24, Russ White wrote: > > FYI. > > :-) > > Russ > >> -----Original Message----- >> From: I-D-Announce [mailto:[email protected]] On Behalf Of >> [email protected] >> Sent: Friday, March 3, 2017 1:38 PM >> To: [email protected] >> Subject: I-D Action: draft-white-openfabric-00.txt >> >> >> A New Internet-Draft is available from the on-line Internet-Drafts > directories. >> >> >> Title : OpenFabric >> Authors : Russ White >> Shawn Zandi >> Filename : draft-white-openfabric-00.txt >> Pages : 13 >> Date : 2017-03-03 >> >> Abstract: >> Spine and leaf topologies are widely used in hyperscale and cloud >> scale networks.
