Configuring Softwire Rules

 

You configure softwire rules to instruct the router how to direct traffic to the addresses specified for 6rd or DS-Lite softwire concentrators. Softwire rules do not perform any filtration of the traffic. They do not include a from statement, and the only option in the then statement is to specify the address of the 6rd or DS-Lite softwire concentrator.

Softwire rules are supported on Multiservices 100, 400, and 500 PICs on M Series routers, and on MX Series routers equipped with Multiservices DPCs. Starting in Junos OS release 17.4R1, softwire rules for DS-Lite are supported on MX Series routers with MS-MPCs and MS-MICs.Starting in Junos OS release 19.2R1, softwire rules for DS-Lite are supported on MX Virtual Chassis and MX Broadband Network Gateway (BNG) routers.

You can create a softwire rule consisting of one or more terms and associate a particular 6rd or DS-Lite softwire concentrator with each term. You can include the softwire rule in service sets along with other services rules.

To configure a softwire rule:

  1. Assign a name to the rule.
  2. Specify the match direction.
  3. Assign a name for the first term.
  4. Associate a 6rd or DS-Lite softwire concentrator with this term.

    Or

  5. Repeat Steps 3 and 4 for as many additional terms as needed.
