Addressing Examples
Examples of OSI network and GOSIP NSAP addresses using the ISO
IGRP implementation are described in the next sections.
The OSI network NSAP address format is illustrated as:
| Domain|Area| System ID| S| 47.0004.004D.0003.0000.0C00.62E6.00
This is an example of the GOSIP NSAP address structure. This struc-
ture is mandatory for addresses allocated from the International Code
Designator (ICD) 0005 addressing domain. Refer to the GOSIP docu-
ment, U.S. Government Open Systems Interconnection Profile (GO-
SIP), Draft Version 2.0, April 1989, for more information.
| Domain| Area|System ID| S|
47.0005.80.ffff00.0000.ffff.0004.0000.0c00.62e6.00

Routing Table Example
You enter static routes by specifying NSAP prefix and next-hop NET
pairs (by using the
clns route command). The NSAP prefix can
be any portion of the NSAP address. NETs are similar in function to
NSAP addresses.
If an incoming packet has a destination NSAP address that does not
match any existing NSAP addresses in the routing table, the Cisco IOS
software will try to match the NSAP address with an NSAP prefix to
route the packet. In the routing table, the best match means the longest
NSAP prefix entry that matches the beginning of the destination
NSAP address.
