Hi Joe And the use case for wanting to do subnet emulation is….?
That‘s my question Dave From: Joe Touch [mailto:[email protected]] Sent: Friday, August 12, 2016 8:20 PM To: David Allan I <[email protected]> Cc: [email protected]; Bocci, Matthew (Nokia - GB) <[email protected]> Subject: Re: [nvo3] FW: Call for interest on NVO3 use case draft The typical use case is to support subnet emulation, e.g., a group of links over which broadcast is emulated as with LANE.

It would not be something you would do gratuitously…. SO I’m looking for the draft to provide a use case for this vs. simply mentioning subnetting without any context ☺ Cheers Dave From: nvo3 [mailto:[email protected]] On Behalf Of Joe Touch Sent: Friday, August 12, 2016 5:07 PM To: David Allan I <[email protected]<mailto:[email protected]>>; [email protected]<mailto:[email protected]>; Bocci, Matthew (Nokia - GB) <[email protected]<mailto:[email protected]>> Subject: Re: [nvo3] FW: Call for interest on NVO3 use case draft On 8/12/2016 4:16 PM, David Allan I wrote: 4.2 Why I would subnet my overlay could use some explanation. I normally think of subnetting as a convenient address summarization technique dependent on topology, and with an overlay I don’t have a topology. The topology of an overlay is determined by its tunnels, just as the topology of the underlying net is determined by its links. A subnet in an overlay corresponds either to a single multipoint tunnel or to a set of tunnels that transparently acts as such - just as a subnet in the Internet base network corresponds to a shared access link or a set of links that transparently act as such (e.g., switched ethernet).
