Configure IS-IS Password Authentication
You can assign different authentication passwords for different rout-
ing levels. By default, authentication is disa bled. Specifying Level1 or
Level2 enables the password only for Level1 or L evel2 routing, re-
spectively. If you do not specif y a level, t he default is Le vel1.
In interface configuration mode, configure an authentication password
for an interface:
isis password
password
{level-1 | level-2}
Configure CLNS
Static Routing You do not need to explicitly specify a routing process to use stati
routing facilities. You can enter a specific static route and apply it glo-
bally, even if you have configured the router for ISO IGRP or IS-IS dy-
namic routing.
To configure a static route, complete the tasks in the following sec-
tions. Only enabling static routes is required; the remaining tasks may
be necessary for certain applications, but are otherwise optional.
zEnable Static Routes
zConfigure Variations of the Static Route
zMap NSAP Addresses to Media Addresses

Enable Static Routes

To configure static routing, you must enab l e C LNS on th e router and
on the interface. CLNS routing is enabled on the router by default
when you configure ISO IGRP or IS-IS routing protocols. NSAP ad-
dresses that start with the NSAP prefix you specify are forwarded to
the next-hop node.
In global configuration mode, configu r e CLNS on the router:
1. Configure CLNS.
clns routing
2. Assign an NSAP address to the router if the router has not been
configured to route CLNS packets dynamically using ISO IGRP
or IS-IS.
clns net {

net-address

|
name
}
3. Enter a specific static route.
clns route

{

next-hop-net

}
