IPv4 to IPv6 network migration by Rodney Smith For CS

222 Overview Requirements for transition to an IPv6 network. Steps towards migration to an IPv6 network.

333 Requirements for transition to an IPv6 network The IPv6 network should perform just as well as the IPv4 network. (ex. Enough memory) Network Management tools for IPv6 network. (ex. Cisco Works) No disruption in service. (ex. Enough CPU) Address allocation.

444 Steps Towards IPv6 migration Obtain IPv6 address space allocation. Can obtain via Regional Internet Registry. (ex. Ripe NCC) The more addresses obtained the better but should not be a problem with IPv6 IPv6 Address allocation

555 Steps Towards IPv6 Migration In IPv4 we would use variable length subnet masks to provide a hierarchical way of assigning addresses In IPv6 we are not restricted as much and can assign one sized mask to all sites. Plan how addresses will be assigned between network sites.

666 Steps Towards IPv6 Migration Must be able to provide a way to monitor IPv6 enabled network with IPv6 enabled mangement tools. Example of one such tool is Cisco Works Network Management tools

777 Steps Towards IPv6 Migration Simple IPv4 Network for Medium to Large networks Transition Path for IPv4 Network

888 Steps Towards IPv6 Migration Dual-Stack 6to4 tunnel Tunnel Broker Layer 2 VPN Transition Path for IPv4 Network

999 Steps Towards IPv6 Migration 6PE Future protocol 6VPE Transition Path for IPv4 Network

10 Steps Towards IPv6 Migration OSPFv3 ISIS for IPv6 BGP-4+ RIPng (don’t use this!) Routing Protocol

11 Steps Towards IPv6 Migration WinXP & Win2k are IPv6 compatible. Enable all endpoints of single site after upgrade of routers. Make sure you plan and test how this upgrade would occur. Enable Endpoints of network
