Usage Information
Use this command to confirm that the neighbor adjacencies are operating correctly. If
you suspect that they are not, you can verify the specified area addresses of the routers
by using the show isis neighbors command.
The following describes the show isis neighbors command shown in the following
example.
Field Description
System Id The value that identifies a system in an area.
Interface The interface, slot, and port in which the router was discovered.
State The value providing status about the adjacency state. The range
is Up and Init.
Type This value displays the adjacency type (Layer 2, Layer 2 or both).
Priority IS-IS priority the neighbor advertises. The neighbor with highest
priority becomes the designated router for the interface.
Uptime Displays the interfaces uptime.
Circuit Id The neighbor’s interpretation of the designated router for the
interface.
Example
The bold sections below identify that Multi-Topology IS-IS is enabled. This command
displays only one IP address per line.
