ASN-GW configuration

The entire WiMAX network under the same ASN GW must have the same IP subnet. So, all WiMAX interfaces for the BS nodes under the same ASN GW must have an IP address configured under the same IP subnet.
There are two steps for ASN-GW configuration:

Step 1: Configure IP routing parameters
Step 2: Configure GRE tunnel information

IP Routing configuration
1. Right-click on the Router and click edit
2. Click on the IP routing parameters drop down menu
3. In the IP Routing Parameters table, click on Interface information and configure IP address and subnet mask under “Address” (192.0.1.2) and “Subnet Mask” (255.255.255.0)

GRE Tunnel Configuration
1. Repeat steps 1 and 2 above.
2. Click on Tunnel interface instead of Interface information
3. Under “Name”, give a unique name for your tunnel e.g. Tunnel A.
4. Under “Address” configure an IP address but different from the IP address configure in IP Routing. For example 192.1.1.2. Also choose the subnet mask from the drop-down menu.
5. Under “Tunnel Information” click edit and a new window opens.
6. Under “Tunnel source”, type the address that was configured in the IP routing interface i.e. 192.0.1.2
7. Under “Tunnel destination”, type the address that will match the IP address configured in BS IP interface.
8. Under “Tunnel Mode”, choose GRE.

BS configuration
1. Repeat the same steps as above for IP routing and GRE tunnel configuration and make sure the addresses are in the same subnet. For example, the ASN-GW IP addresses are 192.0.1.2 (IP interface) and 192.1.1.2 (Tunnel interface). For the BS, the addresses would be 192.0.1.3 (IP interface) and 192.1.1.3 (Tunnel Interface).
2. Under “Tunnel Source”, type the address that was configured in the IP routing interface i.e. 192.0.1.3
3. Under “Tunnel destination”, type the address that will match the IP address configured in ASN-GW IP interface.
4. Note: Click on “BS Parameters” menu and type the “ASN Gateway IP address” which in this case will be 192.0.1.2.

You do not need to configure Route Maps and in order to check that your GRE tunnels are correctly configured, you have to click on Network Visualiser.
