Demand-dial routing example
This section gives an example of the complexity (and elegance) of demand-dial routing. The following illustration shows the configuration between two offices that want to use demand-dial IP routing.
The Seattle office has a server running Routing and Remote Access that acts as a remote access server and demand-dial router All computers in the Seattle office are connected to the 172.16.1.0 network
subnet mask 255.255.255.0 The Seattle router hereafter referred to as Router 1 has a modem connected to its COM1 port and the phone number of the modem is 555-0111
The New York office has a server running Routing and Remote Access that acts as a remote access server and demand-dial router All computers in the New York office are connected to the 172.16.2.0 network
subnet mask 255.255.255.0 The New York router hereafter referred to as Router 2 has a modem connected to its COM2 port and the phone number of the modem is 555-0122
The user on the computer with the IP address of 172.16.1.10 needs to be able to connect to the user on
The computer with the IP address of 172.16.2.20 and vice versa
