Lab descriptions as per below:
✅ L2 Technologies
1) VLAN (Standard Range, End-to-End VLAN)
2) Trunk (Dot1Q), DTP
3) VTP (V2 & V3)
4) RSTP, MST
5) STP tool kits (Port Fast, BPDU Guard, Root Guard)
6) Etherchannel (L2 - LaCP, PaGP & L3 - LACP)
✅ L3 Technologies
1) OSPF
Authentication (MD5, SHA)
Timer (Hello, Dead Interval)
Network Type (Broadcast, Point-to-Point)
Area (Backbone, None-Backbone)
Default Route (Default-information-orginate, Default-information- orginate-always)
Special Area (Stub, Totally Stub, NSSA, Totall NSSA)
3) BGP
IBGP Peer (Using LoopBack, next-hop-self, update-source)
EBGP Peer
Timers
Authentication (MD5)
Path Selection (Local Preference, AS-Path)
BGP Communities (no advertise, local-as)
BGP Route Filtering (Prefix Lists, Route-Map, AS-Path using regular expression)
Default Route (Default-originate)
3) FHRP
HSRP (Timers, Authentication (MD5))
VRRP (Timers, Authentication (MD5))
✅ IP Services
