Final answer:
To allow routing information to be exchanged between your company's network and the third-party's network over a dedicated WAN connection, you should configure routing protocols on the routers at both ends of the connection.
Step-by-step explanation:
To allow routing information to be exchanged between your company's network and the third-party's network over a dedicated WAN connection, you should configure routing protocols on the routers at both ends of the connection. One commonly used routing protocol is Border Gateway Protocol (BGP), which is designed for connecting networks of different autonomous systems. BGP allows the routers to exchange routing information and determine the best paths for forwarding data packets.
Once the routers are configured with BGP, they will exchange information about the networks they are connected to. Each router will advertise the networks it can reach, and the routers will negotiate and establish the best routes for data to flow between the two networks.
For example, let's say your company's network is using the IP address range 192.168.0.0/24, and the third-party's network is using 10.0.0.0/16. When the routers exchange routing information, they will learn about these network addresses and determine how to reach them. The routers will then update their routing tables to include the routes to these networks, allowing traffic to be forwarded between them.
