Configure settings for a DS-Lite concentrator used to process IPv4 packets encapsulated in IPv6.

The ds-lite statement is supported on MX Series routers with MS-DPCs and on M Series routers with MS-100, MS-400, and MS-500 line Multiservices PICs. Starting in Junos OS release 17.4R1, DS-Lite is supported on MX Series routers with MS-MPCs and MS-MICs.

Options

bytes—Maximum transmission unit (MTU), in bytes, for encapsulating IPv4 packets into IPv6. If the final length is greater than the configured value, the IPv6 packet is fragmented. This option is supported on MX Series routers equipped with MS-DPCs. Starting in Junos OS release 18.1R1, this option is also supported on MX Series routers with MS-MPCs or MS-MICs.

ds-lite-softwire-concentrator—Name applied to a DS-Lite softwire concentrator.

auto-update-mtu—This option is not currently supported.

copy-dscp—Copy DSCP information to IPv4 headers during decapsulation.

flow-limit—Maximum number of IPv4 flows per softwire.

• Range: 0 through 16384 flows

• Range: 0 through 9192 bytes

session-limit-per-prefix—Maximum number of sessions per B4 subnet prefix. This option is supported on MX Series routers equipped with MS-DPCs. Starting in Junos OS Release 18.2R1, this option is also supported on MS-MPCs and MS-MICs.

• Range: 0 through 16384 sessions

softwire-address—Address of the DS-Lite softwire concentrator.
