Migration and inter-working are critical There are few “green-fields” in production All IPv6 deployments have to include transition from or coexistence with IPv4 As IPv6 traffic arrives, infrastructure needs to be ready From management … to LAN infrastructure SSH, Traceroute, pingv6 … to ACLs

Built a seasoned Engineering Team Including members of the team that built the world’s first IPv6 network - Naval Research Lab Proven delivery One of the initial vendors with IPv6 solutions Demonstrated first beta in July ’01 Our modular OS with IPv6 “built-in” An IPv6 platform from the ground up A CLI that incorporate IPv6 - not a “bolt-on”

Don’t implement the vendors topology. A legacy of results : 2003/4/5 : Interoperability testing at the UNH 2004: Black Diamond 6800 awarded IPv6 Forum’s “IPv6 Ready” Phase 1 logo 2007: ExtremeXOS 12.0 awarded IPv6 Forum’s “IPv6 Ready” Phase 2 logo

It’s on your network today You need to manage it Build a plan. Every infrastructure purchasing decision needs to consider IPv6 Build for transition and for long-term coexistence Expect more of your vendor Retain your power to choose
