Migrating to IPv6

To successfully migrate to IPv6 involves maintaining compatibility with the large installed base of IPv4 hosts and routers for the immediate future. To achieve this purpose, software release K.13.01 supports dual-stack (IPv4/IPv6) operation and connectons to IPv6-aware routers for routing IPv6 traffic between VLANs and across IPv4 networks.

Software release K.13.01 supports traffic connections with IPv6-aware routers, but does not support IPv6 routing operation in the switches covered by this guide.

Beginning with software release K.13.01, the switches covered by this guide support the following IPv6 protocol operations:

■receiving IPv6 traffic addressed to the switch

■transmitting IPv6 traffic originating on the switch

■switching IPv6 traffic between IPv6 devices connected to the switch on the same VLAN

■concurrent (dual-stack) operation with IPv4 traffic and devices on the same VLAN

■using a connection to an external, IPv6-configured router, forward IPv6 traffic intended for devices on other VLANs and for traffic that must traverse an IPv4 network to reach an IPv6 destination
