Several differences exist between IS-IS Hello packets used on broadcast interfaces and those used on point-to-point interfaces.
Which of the following statements is FALSE?
IS-IS identifies an intermediate system by its System ID on both LAN and point-to-point circuits. A LAN Hello is transported with a source MAC address and can record that link-layer address for the LAN attachment, but the MAC address does not replace the System ID as the IS-IS neighbor identity. IS-IS defines distinct Level-1 and Level-2 LAN Hello formats, a single point-to-point Hello format, and LAN Hellos carry the LAN ID associated with the DIS.
