Description
Multi-area-adjacency
Specifies the interface name and the router ID to which it is connected.
Internet Address
As Stated
Area
As Stated
MTU
Maximum Transmission Unit in bytes.
Process ID
The Process Identifier.
Router ID
As Stated
Network Type
In multi-area adjacencies, this is a point-to-point network with the neighbor.
