Step 4 – Adding a Default Route when using a Static IP Address
This step is not required when learning a default route dynamically as in step 3 (option B) when
we used DHCP. You need to add a static default route when using IP Routing with a static IP
address or PPPoE with a static IP address. Click the “Route Table” link and then add a static
default route by specifying the destination network and subnet mask as 0.0.0.0. In our example,
the static IP address assigned to us by our ISP is 100.100.100.2 and the default route gateway IP
address set below is 100.100.100.1.
