5 Responses to 6PE Implementation Survey
• two router implementations:
- Cisco Systems
- Juniper Networks
• three implementations on network test equipments:
- Ixia
- Agilent
- Spirent

Compliance Statements
• MUSTsAll the implementations comply with all the “MUSTs"
• SHOULDs/MAYsImplementations on test equipment also supports all (or all but one) "SHOULDs"/"MAYs"
• LABEL ALLOCATION STRATEGY: Cisco implementation allocates and advertises an arbitrary label
Juniper implementation allocates IPv6 Explicit NULL label
Both implementation comply with the [6PE] “MUST” to accept both forms of advertisement
Both Implementations interoperate

Interop Testing
• Basic interoperability between Cisco, Juniper and Ixia has been successfully tested as part of an ISOCORE interop event
See section 3 for details on scope of tests

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.

Next Steps
• This was a necessary step to allow 6PE to move to RFC (as per Routing Area rules)
• let that draft die its natural death
