Chris, I am a little confused of the "loops" you stated at the microphone about the scheme described in "draft-nachum-sarp-03" at the InterArea WG session in Atlanta.
The draft assumes that there is some type of loop prevention mechanism in place (be it RSTP/STP, SPB-M, TRILL, or IS-IS) to prevent loops for Ethernet data frames which don't have TTL. The same mechanism should prevent the loops of ARP/ND frames. Can you draw a scenario on how/why the loop prevention mechanism for Ethernet data frames won't work for ARP/ND frames? Thank you very much. Linda Dunbar
