Day2 Video 2! This video quickly covers the topics we discussed previously, which is vlan/trunk setup. I also gone ahead and discussed the process of setting up router on a stick. Interestingly enough, I did not know that once subinterfaces are setup, the router will actually route packets between the vlans. I double checked the certification guide, and the official answer is as follows:

"Now that the router has a working interface, with IPv4 addresses configured, the router can route IPv4 packets on these subinterfaces. That is, the router treats these subinterfaces like any physical interface in term of adding connected routes, matching those routes and forwarding packets to/from those connected subnets" - Pg 442, Official Cert Guide, CCNA/CCENT ICND1 100-101

Okay, so after typing that out, it makes much more sense that once subterfaces are in, we can ping cross vlans!

Here goes Day2-1 video, Thanks for stopping by!
