    Configuring a Loopback Interface for Transport of GTP Packets

    You must configure a loopback interface on an MX Series router before you can configure GTP services for Broadband Gateway.

    To configure a loopback interface:

    1. Edit the loopback interface.
      [edit]user@host# edit interfaces lo0
    2. Edit the loopback interface unit.
      [edit interfaces lo0]user@host# set unit 1
    3. Edit the loopback interface family.
      [edit interfaces lo0 unit 1]user@host# set family inet
    4. Specify the loopback interface address.
      [edit interfaces lo0 unit 1 family inet]user@host# set address
