Illustration supporting IPv6 first-hop resilience: HSRP versus GLBP in the lab

We staged two mini topologies with parallel captures so you can feel how each protocol reacts under link flap. The article stays inside enterprise routing fundamentals and highlights what interviewers often ask about convergence. You will finish with a one-page comparison you can paste into your portfolio notes.

Reader notes

The comparison sheet from the IPv6 first-hop article went straight into my study vault. I paired it with the blueprint refresh piece for a cleaner narrative in interviews.

Solid pacing. I would like a voice-over version, but the printable timers made up for it.
