Enabling IS-IS for IP Routing
The router is now in Router Configuration mode.
Configure a Network Entity Title (NET) for the routing process that specifies the
ISO network address.
host1(config-router)#net
47.0010.0000.0000.0000.0001.0001.1111.1111.1111.00
Enter Interface Configuration mode, and specify the interface that you want to
actively route IS-IS.
host1(config)#interface atm 2/0
Specify the IS-IS process to apply to the interface. Use the same tag name that
you specified with the router isis command.
host1(config-if)#ip router isis floor12
You can repeat Steps 3 and 4 to apply the IS-IS process to multiple interfaces.
Use to configure an IS-IS routing process on an IP interface.
Before the IS-IS router process is useful, you must assign a NET with the net
command, and enable some interfaces with IS-IS.
Use the tag parameter to specify a meaningful name for a routing process. It
must be unique among all IP routing processes for a given router. If you choose
not to specify a tag name, a null tag is assumed, and the process is referenced
with a null tag. Use the same tag name for ip router isis as you did for the router
isis command.
Example
host1(config-if)#ip router isis floor12
Use the no version to disable IS-IS for IP on the interface.
See ip router isis
Use to configure a NET for a specified routing process. The NET defines the ISO
address and consists of an area address or ID, a system ID, and a selector.
You must configure a minimum of one NET.
You can have a maximum of three NETs per router.
You can manually add multiple area IDs by adding multiple NETs with the same
system ID.
There is no default value; net must be configured for an IS-IS process to start.
Multiple NETs can be temporarily useful when there has been a network
reconfiguration where either multiple areas are merged, or one area is in the
process of being split into more areas. Multiple area addresses enable you to
renumber an area slowly, without needing to set aside time to renumber areas
all at once.
