One of the key features of the Internet is its ability to dynamically adjust to network changes, ensuring messages reach their destination even when link failures occur.
Even though route discovery is a critical facility of IP networks, the subject is often regarded as wizardry with its secrets closely guarded by a select few.

PTT’s online course covering “IP routing” provides a clear yet detailed guide to the operation and facilities of route discovery protocols. This interactive course has recently been updated and expanded to explain how the security of the routing process can be improved.
