offices and the headquarters are required to communicate with each other on a regular basis. As
you are using demand-dial connections, you do not want the routing updates to be broadcast
throughout the network. However, for reliable communications, any changes to the network should
be sent to the routers configured on the network. Every router in the network is a server running
Windows Server 2003. Which of the following protocols will you use on the routers?

A.
RIP 1
