Interface synchronization

Interface information is synchronized for interfaces such as PTPT, broadcast, and non-broadcast. Interface wait time is not synchronized to the standby module. If an interface waits for 30 seconds to determine the identity of the designated router (DR) or the backup designated router (BDR), and if the standby module takes over, the wait timer starts again and takes another 40 seconds for the interface state to change from waiting to BDR, DR, or DROther.
