• Assign ports to the VLANs. The physical ports participating in the IS-IS network must be assigned to
the created VLANs. Assigning ports to a VLAN is described in “Assigning Ports to VLANs,” in the
OmniSwitch 6800/6850/9000 Network Configuration Guide.
• Set the area ID (optional). The routers participating in the IS-IS network must be assigned an area
identification number. The area ID is a part of the Network Service Access Point (NSAP) address,
which identifies a point of connection to the network, such as a router interface. The area identification
number assignment is discussed in “Creating an IS-IS Area ID” on page 3-16.
Activating IS-IS
For IS-IS to run on the router, the advanced routing image must be installed. (For information on how to
install image files, refer to the OmniSwitch 6800/6850/9000 Switch Management Guide.)
After the image file has been installed onto the router, you need to load the IS-IS software into the
memory and enable it, as described below:
Loading the Software
To load the IS-IS software into the router’s running configuration, enter the ip load isis command at the
system prompt:
-> ip load isis
The IS-IS software is now loaded into the memory, and can be enabled. IS-IS is not loaded on the switch
by default.
Enabling IS-IS
Once the IS-IS software has been loaded into the router’s running configuration (either through the CLI or
on startup), it must be enabled. To enable IS-IS on a router, enter the ip isis status command at the CLI
prompt, as shown:
-> ip isis status enable
Once IS-IS is enabled, you can begin to set up IS-IS parameters. To disable IS-IS, enter the following:
-> ip isis status disable
Removing IS-IS
To remove IS-IS from the router memory, it is necessary to manually edit the boot.cfg file. The boot.cfg
file is an ASCII text-based file that controls many of the switch parameters. Open the file and delete all
references to IS-IS.
For the operation to take effect the switch needs to be rebooted.
