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. |
