    Example: Configuring Shared IPv6 Interfaces

    This example explains how to create a shared IPv6 interface over a layer 2 logical interface.

    Requirements

    This example uses the following software and hardware components:

    • JunosE Release 7.1.0 or higher-numbered releases
    • E Series router (ERX7xx models, ERX14xx models, the ERX310 router, the E120 router, or the E320 router)
    • ASIC-based line modules that support Fast Ethernet or Gigabit Ethernet

    Overview

    You can create multiple shared IPv6 interfaces over the same layer 2 logical interface—for example, atm 5/3.101—enabling more than one IPv6 interface to share the same logical resources.

    Creating a Shared IPv6 Interface over a Layer 2 Logical Interface

    To share IPv6 interfaces:

    1. Create a layer 2 interface.
      host1(config)#interface atm 5/3 host1(config-if)#interface atm 5/3.101
    2. (Optional) Create a primary IPv6 interface.
      host1(config-if)#ipv6 address 1::1/64 host1(config-if)#exit
    3. Create the shared IPv6 interface.
      host1(config)#interface ipv6 si0
    4. Associate the shared IPv6 interface with the layer 2 interface by the following method:
      host1(config-if)#ipv6 share-interface atm 5/3.101
    5. To fully configure the shared interface, assign an address (or make the interface unnumbered).
      host1(config-if)#ipv6 address 1::1/64
