Configuring IS-IS IS-IS Application Example
OmniSwitch AOS Release 7 Advanced Routing Configuration Guide March 2015 page 3-31
IS-IS Application Example
This section will demonstrate how to set up a simple IS-IS network. It uses two routers, each with an area.
Each router is a L1-L2 capable router and can communicate with different areas. This section will
demonstrate how to set it up by explaining the necessary commands for each router.
The following diagram is a simple IS-IS network. This network will be created using the steps explained
below.
Simple IS-IS Network
Step 1: Prepare the Routers
The first step is to create the VLANs on each router, add IP interface to the VLAN, and assign port to the
VLAN.
The commands to setup VLANs are shown below:
Router 1
-> vlan 5 name vlan-isis
-> ip interface vlan-isis address 10.4.1.1 mask 255.0.0.0 vlan 5
-> vlan 5 port default 1/10
-> ipv6 interface vlan-isis vlan 5
-> ipv6 address 2001::1/64 vlan-isis
Router 2
-> vlan 5 name vlan-isis
-> ip interface vlan-isis address 10.4.1.2 mask 255.0.0.0 vlan 5
Note. The ports will be statically assigned to the router, as a VLAN must have a physical port assigned to it
for the router port to function. However, the router could be set up in such a way that mobile ports are
dynamically assigned to VLANs using VLAN rules. See the chapter titled “Defining VLAN Rules” in the
OmniSwitch AOS Release 7 Network Configuration Guide.
