15.10 IPv6 Network Compatibility
Cisco ONS 15xxx products can function in an IPv6 network when an internet router that supports
Network Address Translation - Protocol Translation (NAT-PT) is positioned between the GNE, such as
an ONS 15454 DWDM, and the client workstation. NAT-PT is defined in RFC-2766. IPv4 and IPv6
nodes communicate with each other using NAT-PT by allowing both IPv6 and IPv4 stacks to interface
between the IPv6 DCN and the IPv4 DCC networks.
NAT-PT binds addresses in IPv6 networks with addresses in IPv4 networks and vice versa to provide
transparent routing for the packets traveling between address types. This requires no changes to end
nodes and IP packet routing is completely transparent to end nodes. It does, however, require NAT-PT
to track the sessions it supports and mandates that inbound and outbound datagrams pertaining to a
session traverse the same NAT-PT router. Protocol translation is used to extend address translation with
protocol syntax/semantics translation.
Note Only Mozilla 1.7 is supported on clients interfacing with IPv6 networks.
