Any Issues Identified? No issues identified with 6PE spec (like ambiguity, holes,..) One point brought to light : while case (b) of inter-AS operations is applicable when arbitrary labels are used, case (b) is not applicable in the case where IPv6 Explicit-Null is used because in that case, it does not result in the use of inter-AS LSPs from ingress 6PE to egress 6PE allowing label switching at every hop including ASBRs. Rather, it results in IPv6 lookup and IPv6 forwarding at the ASBRs. |
