10.Moving the L2 address to the standby device limits the disruption to the address forwarding tables of the L2 switches, which are designed to accommodate rapid connectivity moves. Gratuitous ARP’ing to rebind the L2 address at the termination level requires all connected devices to update their forwarding tables and increases the scope and interdependency of the perturbation.

12.Some implementations address this by allowing the link state of different interfaces to be coupled. These techniques are also applicable to the OSPF solution, but are typically proprietary.
