Chapter 35 Configuring IP Unicast Routing
Configuring ISO CLNS Routing
To return to the default settings, use the no forms of the commands.
Monitoring and Maintaining IS-IS
You can remove all contents of a CLNS cache or remove information for a particular neighbor or route.
You can display specific CLNS or IS-IS statistics, such as the contents of routing tables, caches, and
databases. You can also display information about specific interfaces, filters, or neighbors.
Table 35-13 lists the privileged EXEC commands for clearing and displaying ISO CLNS and IS-IS
routing. For explanations of the display fields, see the Cisco IOS Apollo Domain, Banyan VINES,
DECnet, ISO CLNS and XNS Command Reference, Release 12.2, use the Cisco IOS command reference
master index, or search online.
Step 11
isis circuit-type {level-1 | level-1-2 |
level-2-only}
(Optional) Configure the type of adjacency desired for neighbors on the
specified interface (specify the interface circuit type).
• level-1—a Level 1 adjacency is established if there is at least one area
address common to both this node and its neighbors.
• level-1-2—a Level 1 and 2 adjacency is established if the neighbor is
also configured as both Level 1 and Level 2 and there is at least one
area in common. If
there is no area in common, a Level 2 adjacency is
established. This is the default.
• level 2—a Level 2 adjacency is established. If the neighbor router is a
Level 1 router, no adjacency is established.
Step 12
isis password password [level-1 |
level-2]
(Optional) Configure the authentication password for an interface. By
default, authentication is disabled. Specifying Level 1 or Level 2 enables
the password only for Level 1 or Level 2 routing, respectively. If you do not
specify a level, the default is Level 1 and Level 2.
Step 13
end Return to privileged EXEC mode.
Step 14
show clns interface interface-id Verify your entries.
Step 15
copy running-config startup-config (Optional) Save your entries in the configuration file.
