[spring] Do you consider "steering large portion of a SD-WAN path over SR domain" as the "application" in the SPRING charter? RE: Updating the SPRING WG Charter

Rob, You said: robjs> You can imagine the SR-TE policy work breaks down this way: we discuss the "application" which is steering traffic onto sets of SR paths, and define a functional specification document for how that works. If that is realised in BGP (as it is being today), IDR owns the

Hi I do not quite get the same warm and fuzzy from the definition when thinking about multicast….. The mapping of the binding SID to local policy is still IMO per path state. For a simple p2p path it is pretty straightforward as the mapping can be to a common policy abstraction at every node

Hi Robert, OK, so I understand this a bit more. Yes, we could introduce a m/c tree in the middle of the network and have the leaves terminate in anything. That would include an SR unicast path and/or a new m/c tree or any combination thereof. What you have to do is to place the correct

Hi Stewart, Nope that would be incorrect assumption. Replication anchors would be where topologically it makes sense. And there may not be at all any multicast trees those subject flows would need to traverse. It is just about efficiency in content distribution. Regards, R. On Tue, Jun 19,

There’s no objection against policies installed at ingress interfaces to an SR domain. Rob correctly states, that the SR architecture does not require per path state at transit nodes. And that’s good and correct. I’d like to see the number of signaling protocols in the SR core network being
