semantic translation for packets. This technology is only suitable for communication between a pure IPv4

node and a pure IPv6 node. For more information about NAT-PT, see "Configuring NAT-PT."

NOTE:

The switch does not support NAT-PT.

6PE

6PE is a transition technology by which Internet service providers (ISPs) can use existing IPv4 backbone
networks to allow communications between isolated IPv6 networks.
6PE adds labels to the IPv6 routing information for customer networks and advertises the information into

the IPv4 backbone network over Internal Border Gateway Protocol (IBGP) sessions. IPv6 packets are

labeled and forwarded over tunnels on the backbone network. The tunnels can be GRE tunnels or MPLS
LSPs. For more information about 6PE, see Layer 3—IP Routing Configuration Guide.
