IPv6 Roadmap Release 2.5 IPv6 Multicast Phase II System Management MBGP PIM-SM Bi-Dir ASM Multicast Listener Discovery (MLDv1 & v2) RFC 2710 + draft v2 System Management IPv6 Multicast Routing MIB (enterprise) OSPFv3 MIB (draft-ietf-ospf-ospfv3-mib-06.txt) IPv6 BGP4 MIB (enterprise) IPv6 PIM MIB (enterprise) In addition, SSM translation is supported for IPv4 in 2.4; and may be for IPv6 in 2.5. This allows you to have an SSM cloud in your core even if the host don’t support IGMPv3 (MLDv2 if IPv6). Windows XP supports IGMPv3 but not MLDv2…only major operating system that supports MLDv2 is FreeBSD. 16-Nov-18

Internal IPv6 Protocol Test Results Use Tahi and Spirent for IPv6 conformance testing Perform interoperability testing with Cisco and Juniper Successfully tested the following: BGP4+ 4M paths (or 300 peers with 12k-14k IPv6 prefixes each) 300 peers OSPFv3 15,000 IPv6 routes 300 neighbors ISIS for IPv6 200 adjacencies Max forwarding table entries Max static routes 14,000 IPv6 routes BGP peer capacity is for both IPv4 and IPv6 combined since it’s an integrated protocol. 16-Nov-18

Internal IPv6 Protocol Test Results OSPFv3 Perform interoperability testing with Cisco and Juniper Use Anvil and Spirent for conformance testing Use IXIA and Spirent for emulation In-house developed tests: ~250 Tested with 300 neighbors while redistributing 15k IPv6 routes Tested with 200 neighbors and 20*20 grid (total of ~2000 LSAs) Convergence Test Results: Test Description Convergence Time* Time to receive 10k redistributed routes from single neighbor: 68 sec Time to receive 20k redistributed routes from single neighbor: 84 sec Time to receive LSAs for 20*20 grid from single neighbor: 50 sec Time to receive LSAs for 40*40 grid from single neighbor: 55 sec Conformance testing is to test for conformance to standard Emulation is stress and scalability testing (tools are topology generators) For convergence tests – Procket router is connected to IXIA; tester issues a ‘no shutdown’ and starts the clock when the interface comes up (as shown in debug mode). * Measured as time from interface up to routes installed in hardware. 16-Nov-18

Spirent IPv6 Performance Test Results Tests performed in September 2003 At Spirent’s Calabasas, California facility PRO/8812 High-Availability Router running PRO/1 software v2.2 Test equipment Spirent TeraRouter Tester version 3.0 with TeraMetrics 1G and 10G cards Fully Loaded PRO/8812 240 Ports of 1000BaseSX 24 Ports of 10GBaseLX Single packet size and IMIX tests IMIX was 2:1:1 ratio of 76, 576, and 1500 byte packets Traffic fully meshed Each port had a flow to every other 1G and 10G port Very important notes: These tests were designed to allow a third party (Spirent) to test a fully loaded chassis. This chassis had 240 ports of 1G Ethernet (called the ‘edge’) and 24 ports of 10G Ethernet (called the ‘core’). There was no attempt to optimize the tests for latency or try and produce a ‘speed run’. These tests were meant to see what the chassis would do under fully loaded conditions with IPv6 traffic. 16-Nov-18

The AVERAGE (or MEAN) latency is the sum of all of the average latencies reported by the test tool for 10G to 1G traffic flows, divided by the total number of flows. This produces an ‘average of an average’. The MEDIAN latency is the statistical representation of the middle of the latency numbers. The MEDIAN is often used to give a representation of how skewed the figures are from lowest to highest. The MEDIAN latency for the IMIX is very different from the AVERAGE because of the wide range of values when using the different packet sizes. The latency numbers on this slide will be very high compared to the next slide, because the traffic flows being measured here are subject to the queuing done when the egress is a 1G port. That is, because the ingress is faster than the egress, these figures will be higher than those on the next slide. 1736.93 880.70 255.25 76 576 1500 IMIX 16-Nov-18
