Command Reference Guide – Routing Protocol

network-entity-title: Network entity title in the form of X...X.XXXX....XXXX.00, with the

12 "X" in the middle as system ID of the router, the last "00" as the SEL and the "X...X"

in the front as the area address.

Use the network-entity command to configure the network entity title (NET) for an

IS-IS routing process.

Use the undo network-entity command to delete a NET.

There is no NET by default.

A NET is a network service access point (NSAP), and it is in the range of 8 to 20 bytes

A NET has three parts: The first part is area ID, which ranges from 1 to 13 bytes. The

routes of the same area have the same area ID. The second part is the router's

system ID of 6 bytes, which is unique within the whole area and backbone area. The

third part is SEL, the ending byte with the value of 00. You need to configure only 1

NET for a router. When repartitioning an area, such as merging or splitting, you can

reconfigure the router to ensure correct and continuous routing.

Related command: isis, and isis enable.

# Specify the NET as 10.0001.1010.1020.1030.00, of which 10.0001 is the area ID

and 1010.1020.1030 is the system ID.
