ES-IS protocol. The router dynamically discovers all ESs running the
ES-IS protocol. ESs that are not running the ES-IS protocol must be
configured statically.
It is sometimes desirable for a router to have a neighbor configured
statically rather than learned through ES-IS, ISO IGRP, or IS-IS.
Warning: It is necessary to use static mapping only for ESs that do
not support ES-IS. The Cisco IOS software continues to
dynamically discover ESs that do support ES-IS. If you
have configured interfaces for ISO IGRP or IS-IS, the
ES-IS routing software automatically turns on ES-IS for
those interfaces.
In interface configuration mode, enter static mapping information be-
tween the NSAP protocol addresses and the subnetwork point of at
tachment (SNPA) addresses (media) for ESs or ISs, as needed:
z
Configure all end systems that will be used when you manually
specify the NSAP-to-SNPA mapping.
clns es-neighbor
nsap snpa
z
Configure all intermediate systems that will be used when you
manually specify the NSAP-to-SNPA mapping.
clns is-neighbor
nsap snpa
For more information, refer to Configure CLNS over WANs.
Warning: The SNPA is a data link layer address (such as an Ether-
net address, X.25 address, or Frame Relay DLCI address)
used to configure a CLNS route for an interface.
