Configuring IS-IS IS-IS Application Example
OmniSwitch 6800/6850/9000 Advanced Routing Configuration Guide December 2007 page 3-33
Router 2
-> vlan 5 name vlan-isis
-> ip interface vlan-isis address 10.4.1.2 mask 255.0.0.0 vlan 5
-> vlan 5 port default 1/10
Step 2: Enable IS-IS
The next step is to load and enable IS-IS on each router. The commands for this are shown below (the
commands are the same on each router):
-> ip load isis
-> ip isis status enable
Step 3: Create and Enable Area ID
Now the areas should be created and enabled. The commands for this are shown below:
Router 1
-> ip isis area-id 00.0001
This command created the area for Router 1.
Router 2
-> ip isis area-id 00.0002
This command created the area for Router 2.
Step 4: Configuring IS-IS Level Capability
The router must be configured with the IS-IS level capability, which decides whether the router will route
traffic within an area or between two or more areas.
Router 1
-> ip isis level-capability level-1/2
Router 2
-> ip isis level-capability level-1/2
Note. The default IS-IS level capability is Level-1/2.
Step 5: Create, Enable, and Assign Interfaces
Next, IS-IS interfaces must be enabled. The IS-IS interfaces should have the same IP address as the IP
router ports created above in “Step 1: Prepare the Routers” on page 3-32.
Router 1
-> ip isis interface vlan-isis
-> ip isis interface vlan-isis status enable
