Display route IP for request timeout hop issue.
Demonstrates my limited understanding yet highlights an effective approach.
It's coming together nicely in my mind. Thanks again for the details—it really clears things up. Also, appreciating your support! @Windows7ge
Interesting perspective. If we delve deeper technically, the TTL increase isn't simply +1 or -1 but follows a doubling pattern. For example: 1 → 2 → 4 → 8 → 16 → 32... Each step doubles the value. Your observation is correct. However, attempting to bypass this security mechanism would be against forum rules, as it relates to circumventing protections. The topic is considered sensitive and discussing it could lead to consequences like bans.
Because each step only reduces one position, you must add 1 each time. This ensures the count reaches the next device in the sequence.
Based on what I learned about TTL, it functions using a binary system rather than a decimal one. Each transition moves by a value of +1, but the way it displays the information to the user follows powers of 2—such as 1, 2, 4, 8, 16, and so on. As the signal passes through these stages, it gets reduced by half at each step until it reaches either 1 or 0, at which point the port details are retrieved. Would you feel that's correct, or have your understanding changed after taking more Cisco networking courses?
I'm not familiar with that concept. I've always understood hop count as the number of times a router handles a packet in the sequence. Confusion can arise when moving through virtual interfaces—like one hop to the physical port and another to the virtual one, or just one processing if it goes directly through the device. I know the packet size is 8 bits, but I'm not sure how that fits here.
I’ll need to revisit this later if no one provides the solution. Right now I’m a bit tired, so I might say random nonsense, but using the Ping command shows a TTL of 255, then it drops to 127, 63, 31, etc., until it either reaches the destination or gets discarded.
At layer 2, such as MPLS/VPLS, there are additional behaviors that aren't obvious in tools like traceroute.
MPLS is sure to appear in a traceroute when using ICMP with label data. It’s usually not visible because it’s set manually to a different TTL in the outer label through a command at the network edge. The service provider might use IS-IS, which can be supported by CLNP, or there could be an MPLS core with BGP at the edge. This setup serves as a security feature focused on preventing internal IP traffic. You can still observe MPLS ICMP at the customer premises equipment and see MPLS labels along the path. VPLS tunnels eliminate hop visibility.
