Compare IPv6 address · IPv6 prefix length · IPv6 default gateway · Link-local next hop
Concept notes
IPv6 address
Contains 128 bits written as hexadecimal groups separated by colons.
IPv6 prefix length
States how many leading IPv6 bits identify the network.
IPv6 default gateway
Receives traffic for IPv6 destinations outside the local link.
Link-local next hop
Uses a router's FE80::/10 link-local address as the next hop for IPv6 destinations outside the local link.
Review the concept notes, then answer four related questions. That is enough for today; more practice is optional.
Practice the reasoning here
Write or inspect a small Cisco configuration, name the expected show-command evidence, and explain how a frame or packet crosses it.
- State the expected result before changing or testing anything.
- Name the observation, command, log, or report that would confirm it.
- Explain why the closest alternative does not fit the same requirement.
Check the whole objective
This unlocks objective 1.8 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
