Page 5 Conformance, Interoperability and Stress test methodologies for IPv6 Core Routers IPv6 Conformance Benefits GOAL: Conform to RFC, first step before Interoperability testing e.g. test Case bgp4P_rfc_2858_11 Section: RFC 2858, Section 2, page 5: Description: "An UPDATE message that carries the MP_REACH_NLRI must also carry the ORIGIN and the AS_PATH attributes (both in EBGP and in IBGP exchanges). Moreover, in IBGP exchanges such a message must also carry the LOCAL_PREF attribute. If such a message is received from an external peer, the local system shall check whether the leftmost AS in the AS_PATH attribute is equal to the autonomous system number of the peer than sent the message. If that is not the case, the local system shall send the NOTIFICATION message with Error Code UPDATE Message Error, and the Error Subcode set to Malformed AS_PATH". Result: Four SUTs failed the tests. SUTs failed to send a notification if Update Message didnt contain the most-left AS number. Suggestion: Result to be shared with the IETF Inter-Domain Routing Working Group for comment. SUT

OSPFv3 DR/BDR election Process Results: Routers ready to be deployed E.g. iBGP4+ Full Mesh connection Results: One router can not build Multi-hop iBGP session SUT 2SUT 4SUT 3SUT 1

Page 7 Conformance, Interoperability and Stress test methodologies for IPv6 Core Routers IPv6 Performance Benefits GOAL: Are IPv6 routers ready to be deployed? What are their performance? Are the performance of the IPv4 services impacted? How much could we stress the Control Plane? E.g. Sustainable Throughput of OC-48 POS Port at Packet Size 64 bytes with different Percentage of IPv4 and IPv6 Traffic
