Started with layer 2

Had a good study on VTP, pruning, vtp domains, vtp modes, lacp, pagp.

And started with basic L3. Understood how a router actually does routing.(Longest route map, recursive lookup for interface and then encapsulation). Did some PBR and access list not fully comfortable with PBR and access lists. will spend some more time later.

Planning to start with some routing(rip,ospf) will get back to PBR later....
