z
The dead interval set on neighboring interfaces cannot be too short. Otherwise, a neighbor is easily
considered down.
z
The LSA retransmission interval cannot be too short; otherwise, unnecessary retransmissions
occur.
Configuring a DR Priority for an Interface
Follow these steps to configure a DR priority for an interface:
To do…

Optional
Defaults to 1
The DR priority of an interface determines the interface’s qualification in DR election. Interfaces having
the priority 0 cannot become a DR or BDR.
Ignoring MTU Check for DD Packets
When LSAs are few in DD packets, it is unnecessary to check the MTU in DD packets in order to
improve efficiency.
