Have you ever wondered how routers determine the best path to take when multiple options are available? In this intriguing video, we will explore the fascinating world of route precedence. But before we dive in, make sure to check out the previous video on router precedence for a complete understanding of the topic. Now, let’s get started!

Unraveling the Mystery: Bonus Questions
In our previous discussion, we pondered two bonus questions that demanded answers. The first question focused on how the routing table would change after adding a static route. Without further ado, let’s reveal the truth!
Upon entering the static route command, we eagerly examined the routing table’s transformation. Surprisingly, even though we expected significant alterations, we discovered that only subtle changes had occurred. Two routes remained, but the newly added static route overshadowed the EIGRP-learned route. The reason behind this shift lies in the administrative distance assigned to each route. The static route, with an impressive administrative distance of 1, triumphed over the EIGRP’s less favorable 90. Therefore, our newly added static route replaced the existing EIGRP route, leaving us with a modified routing table.
Now that we have unveiled the first secret, let’s proceed to the second question, which delves into the path selection process.
The Nexus of Path Selection: Router 1’s Dilemma
To determine the path chosen by Router 1 when confronted with the IP address 9.99.129, we embarked on a trace route journey. Curiously, regardless of the newly added static route instructing Router 1 to utilize Router 5, we noticed that Router 2 consistently appeared as the first hop. The question lingering in our minds was: why?
The answer lies in the concept of specificity. Although both the static route (a slash 24) and the rip route (a slash 25) encompassed the target IP address, it was the rip route that demonstrated greater specificity. Despite its inferior administrative distance, the rip route took precedence over its counterpart. Consequently, Router 2 emerged as the chosen path in every trace route scenario. This fascinating observation unveils the power of specificity in the realm of routing.
