You can provision an NE as IPv6 enabled only if the node is a SOCKS-enabled or firewall-enabled
GNE/ENE.
IPSec is not supported.
OSPF/RIP cannot be enabled on the LAN interface if NE is provisioned as an IPv6 node.
Static route/Firewall/proxy tunnel provisioning is applicable only to IPv4 address even if the IPv6
is enabled.
In secure mode, IPv6 is supported only on the rear Ethernet interface. IPv6 is not supported on the
front port.
ONS 15600 platforms do not support IPv6 on front port of TSC cards. IPv6 is supported only on the
rear Ethernet interface.
ONS platforms use NAT-PT internally for providing IPv6 native support. NAT-PT uses the IPv4
address range 128.x.x.x for packet translation. Do not use the 128.x.x.x address range when you
enable IPv6 feature.
