Parameter

net: Specifies the NET (Network Entity Title ) in the X…X.XXXX....XXXX.00
format, in which the first "X…X" is the area address, the twelve Xs in the
middle is the System ID of the router, and the 00 in the end is SEL.
Description
Using the network-entity command, you can configure the name of Network
Entity Title (NET) of the IS-IS routing process. Using the undo network-entity
command, you can cancel a NET.
By default, the value is No NET.
NET means the Network Service Access Point (NSAP). The NET field of IS-IS is 8 to
20 bytes.
It consists of three parts. Part one is area ID, which is variable (1 to 13 bytes), and
the area IDs of the routers in the same area are identical. Part two is system ID (6
bytes) of this router, which must be unique in the whole area and backbone area.
Part three, the last byte "SEL", whose value must be "00". Usually, one router can
be configured with one NET. When the area is redesigned by combination or
separation, after reconfiguration, the correctness and continuity of the routes
must be ensured.
For the related commands, see isis and isis enable.
Example
Specify NET as “10.0001.1010.1020.1030.00”, in which the system ID is
“1010.1020.1030”, area ID is “10.0001”.
