Hello participants to v6ops WG, We have just submitted draft-petrescu-relay-route-pd-problem-00 http://tools.ietf.org/html/draft-petrescu-relay-route-pd-problem-00 "Route Problem at Relay during DHCPv6 Prefix Delegation" M. Boucadair (France Telecom) L. Yeh (Freelancer Technologies) A. Petrescu (CEA). It presents a problem of routing at Relay during Prefix Delegation of DHCPv6; also lists some solutions I-Ds. The problem may be relevant in the DHC WG, at the Broadband Forum and maybe at 3GPP. Please comment on this draft.
