I dropped an AP on the canvas, set its SSID to LabWiFi and WPA2-PSK to Networking123, then added a PC as a wireless station. When I type the passphrase exactly it associates fine and I can ping the gateway. But if I mistype even one character of the PSK, or put the SSID in the wrong case (labwifi), the station just never joins — no error that says "wrong password", it just sits there unassociated.
Why does a single wrong character make the whole thing fail silently? Is the SSID part of the password check somehow, or are those two separate things? Trying to build the right mental model here. 🙏
Coming from IPv4 where every interface just had one address I configured (or got from DHCP). In the NetForge lab I enabled IPv6 on a router interface and suddenly show ipv6 interface lists two addresses: an fe80:: one I never typed, plus the 2001:db8:: global I set.
A few things I can't map back to IPv4:
fe80:: address for and why does it appear automatically?Trying to build the right mental model before I go further. Thanks!
I just moved from the RIP chapter to EIGRP in the course and I'm a bit confused. RIP was simple — count the hops, lowest wins, max 15. But EIGRP apparently uses this composite metric with bandwidth and delay (and load/reliability?) and I don't really get why it's more complicated.
What problem does bandwidth + delay actually solve that hop count doesn't? And when EIGRP picks a path, which one "wins" — the fewest hops or something else? Trying to build the right mental model before I do the lab. 🙂
