Configuring a Static or Dynamic IP Demux Subscriber Interface over Aggregated Ethernet

You can configure a subscriber interface using a static or dynamic IP demultiplexing (demux) logical interface stacked on an aggregated Ethernet logical interface. Optionally, you can configure the aggregated Ethernet logical interface to support one-to-one active/backup link redundancy or traffic load balancing.

  1. Configure the aggregated Ethernet interface.
    1. Configure the number of aggregated Ethernet interfaces on the router.

      See Configuring the Number of Aggregated Ethernet Interfaces on the Device.

    2. Configure the aggregated Ethernet interface.

      See Configuring an Aggregated Ethernet Interface.

    3. (Optional) Configure LACP.

      See Configuring LACP for Aggregated Ethernet Interfaces.

    4. (Optional) Configure the minimum number of links.

      See Configuring Aggregated Ethernet Minimum Links.

    5. (Optional) Configure the link speed.

      See Configuring Aggregated Ethernet Link Speed.

    6. (Optional) Configure the aggregated Ethernet logical interface to support one-to-one active/backup link redundancy or traffic load balancing.

      For general instructions, see Configuring Aggregated Ethernet Link Protection.

      Note:

      Link protection is required if you want to configure hierarchical CoS on the aggregated Ethernet interface. For more information, see Configuring Hierarchical CoS for a Subscriber Interface of Aggregated Ethernet Links.

  2. Configure the aggregated Ethernet logical interface as the underlying interface to support the static or dynamic IP demux subscriber interface.

    The aggregated Ethernet interface needs to support demultiplexing of incoming traffic to the Ethernet links based on IPv4 destination or source addresses in the incoming packets. In addition, you must configure the IP address of each link.

    See Configuring an IP Demultiplexing Interface.

  3. Configure the static or dynamic IP demux interface.
    Note:

    IP demux interfaces currently support only the Internet Protocol version 4 (IPv4) suite (family inet).

    VLAN demux interfaces support the Internet Protocol version 4 (IPv4) suite (family inet) and the Internet Protocol version 6 (IPv6) suite (family inet6).

    VLAN demux subscriber interfaces over aggregated Ethernet physical interfaces are supported only for MX Series routers that have only MPCs installed. If the router has legacy DPC card in addition to MPCs, the CLI accepts the configuration but errors are reported when the subscriber interfaces are brought up.

  4. (Optional) Configure subscriber management services on the subscriber interface.
