    Say CE is mutihomed to PE1 and PE2. PE1 is primary.

    PE1 "show vpls connections" will show UP to remote PEs.

    PE2 "show vpls connections" will show a down state (don't remember which exact flag)

    PE1 interface facing CE will be UP/UP

    PE2 Interface facing CE. Physical interface should still be UP/UP, but logical system has a CCC down

    On CE, since it's not an ae bundle, it can figure out PE1 is primary (via mac learning?)

    Here's a good KB example
