CCNP BSCI Notes – Understanding Simple Single-Area OSPF
OSPF Fundamentals Link-state routing protocols utilize more internal resources in favor of reducing bandwidth consumption. All OSPF routers in an area share the same Link State Database (LSDB). Link State Advertisements (LSAs)…

Full mesh formula: n(n-1)/2 Example: To create a mesh between 8 nodes, 8 * (8-1) / 2 = 28; 28 links are needed. Design concepts Legacy Hierarchical Design Model
CCNP BCMSN Notes – Cisco Unified Wireless Network
Autonomous APs can be burdensome to manage in large numbers; a lightweight solution is preferred. Lightweight Access Points (LAPs) communicate with a centralized Wireless LAN Controller (WLC) through Lightweight Wireless Access Point…

Legacy Authentication Types Open Authentication No authentication is used; any client can associate to an AP. Pre-Shared Key (PSK) A pre-shared static Wired Equivalence Protocol (WEP) key authenticates the client to the…
CCNP BCMSN Notes – Wireless LAN Overview
Frame Transmission Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) is used in 802.11 WLANs to avoid collisions. The Distributed Coordination Function (DCF) handles the transmission of frames. If one station is currently transmitting,…
CCNP BCMSN Notes – Securing with VLANs
VLAN Access Lists (VACLs) VACLs can filter traffic within a VLAN and do not require a routed interface. A VACL can match traffic from a MAC, IP, or IPX access list. VACL…
