    Configuring Virtual Router Routing Instances

    Use virtual router routing instances to divide a QFX Series switch into multiple independent virtual routers, each with its own routing table. Virtual router routing instances enable you to isolate traffic without using multiple devices to segment your network. You can create routing instances for unicast routing protocols and PIM sparse mode.

    Note: The QFX5100, QFX5110, and QFX5200 switches do not depend on the VRF match for loopback filters configured at different routing instances. Loopback filters per routing instance (such as lo0.100, lo0.103, lo0.105) are not supported and may cause unpredictable behavior. We recommend that you apply the loopback filter to the lo0.0 (master routing instance) only.

    To configure virtual router routing instances:

    1. Create a routing instance:
      [edit routing-instances]
      user@switch# set routing-instance-name instance-type virtual-router

      Note: The default routing instance, master, refers to the main inet.0 routing table. The master routing instance is reserved and cannot be specified as a routing instance.

    2. Bind each routing instance to the corresponding interfaces:
      [edit routing-instances]
      user@switch# set routing-instance-name interface device-name:type-fpc/pic/port.logical-unit-number

      Note:

      • You must bind routing instances to interfaces from the Node devices assigned to the network Node group only. If you try to bind routing instances to interfaces from the Node devices assigned to server Node groups, the configuration does not commit.
      • You can bind an interface to one routing instance only.
    3. Create each of the logical interfaces bound to each routing instance:
      [edit interfaces]
      user@switch# set device-name:type-fpc/pic/port unit logical-unit-number family inet address ip-address

      Note: Do not create a logical interface using the family ethernet-switching option in this step. Binding an interface using the family ethernet-switching option to a routing instance can cause the interface to shut down.

    4. (Optional) Configure routing protocols for the routing instance at the [edit routing-instances routing-instance-name protocols] hierarchy level.
    5. (Optional) Configure routing options for the routing instance at the [edit routing-instances routing-instance-name routing-options] hierarchy level.
