As an example of when a static route is needed, consider the following case:
• Your router has two remote nodes defined. One is an ISP, and the second is for remote
access to your company.
• Your company owns two ranges of IP addresses: 134.177.x.x and 141.251.x.x.
• The remote access router at your company is 134.177.3.28.
When you configured your router, two implicit static routes were created. A default route was
created with your ISP as the gateway, and a second static route was created to the network at
134.177.0.0 with your company's router as the gateway. With no calls currently up, if you attempt
to access a device on the 141.251.0.0 network, your router calls the ISP. The ISP forwards your
request to your company, and the request will likely be denied by your company's firewall.
If a call to your company was already up, your router might have learned by RIP that 141.251.0.0
was available through the company node. Alternatively, you could define a static route, telling
your router that 141.251.0.0 should be accessed through the company node.
