Description
Use the
network-entity
command to configure the Network Entity Title for an IS-IS routing process.
Use the
undo network-entity
command to delete a NET.
No NET is configured by default.
A NET is a special NSAP address with the SEL being 0. The length of the NET is in the range 8 bytes
to 20 bytes.
A NET comprises three parts:
z
Area ID. Its length is in the range of 1 to 13 bytes.
z
System ID. A system ID uniquely identifies a host or router in the area and has a fixed 6-byte
length.
z
SEL. It has a value of 0 and a fixed 1-byte length.
For example, a NET is ab.cdef.1234.5678.9abc.00, where,
Area ID is ab.cdef, system ID is 1234.5678.9abc, and SEL is 00.
