Description

Configure softwires for IPv6 dual-stack lite (DS-Lite). DS-Lite allows migration to an IPv6 access network without changing end-user software. IPv4 users can continue to access IPv4 internet content using their current hardware, while IPv6 users are able to access IPv6 content.

Options

map-e	Name of the map-e rules configuration.
softwire-name	Name of the softwire configuration.
traceoptions	Traceoptions for Network Security DS-Lite.
mtu-v6	Specify the configured MTU version 6 name for the softwire tunnel.
post-fragmentation	You can enable or disable the post-fragmentations to fragment the IPv6 packet. By default the post-fragmentation is off.
pre-fragmentation	You can enable or disable the pre-fragmentation or clear the df bit in the IP packet.

The remaining statements are explained separately. See CLI Explorer.

Required Privilege Level

security—To view this statement in the configuration.

security-control—To add this statement to the configuration.
