Multihomed proxy advertisement

More Information:

    Multihomed proxy advertisement

    Junos OS now provides enhanced support to proxy advertise the MAC address and IP route entry from all leaf devices that are multihomed to a customer edge (CE) device. Using proxy advertisement prevents traffic loss when one of the connections to the leaf device fails. To support the multihomed proxy advertisement, all multihomed provider edge (PE) devices should have the same multihomed proxy advertisement bit value. The multihomed proxy advertisement feature is enabled by default, and Junos OS uses the default multihomed proxy advertisement bit value of 0x20.
