Introduction to IPv6
Migrating to IPv6
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 and greater supports dual-stack
(IPv4/IPv6) operation and connections to IPv6-aware routers for routing IPv6
traffic between VLANs and across IPv4 networks.
N o t e Beginning with release K.13.01 the software 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
