Configuring a DS-Lite Softwire Concentrator

To configure a DS-Lite softwire concentrator:

  1. Assign a name to the DS-Lite softwire concentrator.
    [edit services softwire softwire-concentrator]user@host# edit ds-lite ds-lite-softwire-concentrator
  2. Specify the address of the softwire tunnel.
    [edit services softwire softwire-concentrator ds-lite ds-lite-softwire-concentrator] user@host# set softwire-address address
  3. Specify the MTU for the softwire tunnel.
    [edit services softwire softwire-concentrator ds-lite ds-lite-softwire-concentrator] user@host# set mtu-v6 mtu-v6

    Note: This option sets the maximum transmission unit when encapsulating IPv4 packets into IPv6. If the final length is greater than the MTU, the IPv6 packet will be fragmented. This option is mandatory since it depends on other network parameters under administrator control.

  4. To copy DSCP information from the IPv6 header into the decapsulated IPv4 header, include the copy-dscp statement.
    [edit services softwire softwire-concentrator ds-lite ds-lite-softwire-concentrator] user@host# set copy-dscp
  5. Specify the maximum number of flows for the softwire
    [edit services softwire softwire-concentrator ds-lite ds-lite-softwire-concentrator] user@host# set flow-limit 1000
