I assume this is possibly some form of "capstone project" homework assignment. What have you accomplished so far? What in particular don't you understand? Are you familiar with Cisco's learning network?

Yesterday, and today, on two different PCs. Noticed I can not rate some posts, and it appears I can rate my own posts. (For last, I write "appears" because I have actually click on stars for my own posts, but they are shown when I hover over them.)...

Working to replace hub-and-spoke (router-to-router) individual VPN tunnels (GRE/IPSec or VTI) with DMVPN but without using default-route. Default-route doesn't lead to the next-hop the hub should use for spokes. With individual tunnels, had indivi...

I believe the answer is yes, which appears contrary to @Flavio Miranda's reply. I suspect what Flavio has in mind is control traffic, like CDP, VTP, DTP, which are considered part of VLAN 1, and are untagged, I also believe, regardless of a trunk po...

What's the port stats for the other side's device? The stats you've posted, shows the interface is running in full duplex mode, but you've 599 output errors, all collisions, which shouldn't be happening in full duplex mode (or so I believe). Normall...
