    Manual Routers

    Support: End
    Default: No router IDs     Value: Set of LAN addresses

    Manually entered IDs of routers. If this set is empty, the
    circuit will auto-configure the routers. This characteristic is
    supported only if the circuit's characteristic type is csma-cd.
    For Tru64 UNIX, a maximum of 5 routers can be in the set.

    Example:

    add routing circuit csmacd-1 manual routers -
