Configuring IS-IS
The following example shows how to add Ethernet 1/2 interface to an IS-IS instance:
switch# config t
switch(config)# interface ethernet 1/2
switch(config-if)# ip router isis Enterprise
switch(config-if)# copy running-config startup-config
Shutdown IS-IS on an Interface
You can gracefully shut down IS-IS on an interface. This removes all adjacencies and stops IS-IS traffic
on this interface but preserves the IS-IS configuration.
To disable IS-IS on an interface, use the following command in interface configuration mode:
Configuring IS-IS Authentication in an Area
You can configure IS-IS to authenticate LSPs in an area.
BEFORE YOU BEGIN
Ensure that you have enabled the IS-IS feature (see the “Enabling the IS-IS Feature” section on
page 9-7).
Ensure that you are in the correct VDC (or use the switchto vdc command).
