The only text I can see is the following:
“Each network device receives the Path Tracking packet from its upstream device, makes a copy of it and passes the copy to its CPU. “ I don’t see any mechanism being proposed in the draft.

If this assumption is broken, the solutions proposed in this draft may not be effective.

The only option I can think of is TTL expiry, otherwise it won’t work, the way it is defined now, Thx Shahram _______________________________________________ nvo3 mailing list [email protected]<mailto:[email protected]> https://www.ietf.org/mailman/listinfo/nvo3
