If a coworker improperly configured the AS number on a network device, this could result in:
A) Routing conflicts and communication issues
B) Improved network performance
C) Enhanced security measures
D) Redundant paths for data transmission
The Correct answer and Explanation is:
The correct answer is A) Routing conflicts and communication issues.
When a coworker improperly configures the Autonomous System (AS) number on a network device, it can have significant repercussions for the overall network’s routing capabilities and communication integrity. An AS number is a unique identifier assigned to an Autonomous System, which is a collection of IP networks and routers under the control of a single organization that presents a common routing policy to the internet.
If the AS number is incorrectly configured, it can lead to routing conflicts in several ways. First, routers use the AS number to determine the best path for data packets. An incorrect AS number can cause routers to misinterpret the source or destination of the packets, leading to suboptimal routing decisions. This can result in packets being sent on incorrect paths or getting dropped entirely, causing communication issues between devices or network segments.
Moreover, routing protocols such as Border Gateway Protocol (BGP) rely heavily on AS numbers to establish relationships between different networks. If the AS number is misconfigured, BGP may not properly form peering sessions with neighboring routers. This could prevent the router from receiving essential routing updates, leading to outdated or incorrect routing tables. As a consequence, data packets may fail to reach their intended destinations, resulting in significant delays or complete communication breakdowns.
In addition, the misconfiguration can trigger routing loops, where packets circulate indefinitely without reaching their destination, further degrading network performance. This can also put unnecessary strain on network resources, leading to increased latency and potential downtime.
In summary, improper configuration of the AS number can create routing conflicts and communication issues, disrupting the reliability and efficiency of network operations. Therefore, accurate AS number configuration is crucial for maintaining a well-functioning network.
