Optional.
An interface can establish either the
Level-1 or Level-2 adjacency by
default.
Configuring the network type of an interface as P2P
Perform this task only for a broadcast network that has up to two attached routers.
Interfaces with different network types operate differently. For example, broadcast interfaces on a
network must elect the DIS and flood CSNP packets to synchronize the LSDBs, but P2P interfaces on a
network do not need to elect the DIS, and have a different LSDB synchronization mechanism.
If only two routers exist on a broadcast network, configure the network type of attached interfaces as P2P
to avoid DIS election and CSNP flooding, saving network bandwidth and speeding up network
convergence.

Optional.
By default, the network type
of an interface depends on
the physical media.
