RIP
What RIP is (and isn’t) Type: Distance-vector IGP using the Bellman-Ford algorithm. Metric: Hop count (each router = +1). Best path = fewest hops. Infinity: 16 hops (so any route…

1) Aruba AP Tunnels — Architecture & Forwarding A. Big picture In Aruba’s controller–based architecture (Campus AP / RAP), each AP: Discovers one or more controllers (L2 ADP, DHCP option…
802.11h — Spectrum Management (5 GHz) Why it exists: Early 5 GHz Wi-Fi risked interfering with radar and other incumbents. 802.11h added mechanisms so Wi-Fi could legally share 5 GHz.…
1. Channel bonding What It Is Channel bonding is the process of combining two or more adjacent 20 MHz Wi-Fi channels into a single, wider channel to increase throughput. In…
1. EIRP (Equivalent/Effective Isotropic Radiated Power) Definition EIRP is the total RF power radiated from an antenna in the direction of its strongest emission, assuming the antenna radiates equally in…
What RF bands are Wi-Fi’s main frequency bands (2.4, 5, 6 GHz) UNII sub-bands in 5 GHz and 6 GHz Channel numbering & widths Range vs. speed trade-offs Regulatory aspects…
1. What IEEE 802.11 Is IEEE 802.11 is a family of standards created by the Institute of Electrical and Electronics Engineers (IEEE) for wireless local area networking (WLAN). It defines:…
Route redistribution is the process of sharing routing information between different routing protocols or instances within a network. It’s used when a router needs to advertise routes learned from one…
Administrative Distance (AD) is a metric used by routers to determine the trustworthiness of a routing protocol when multiple protocols provide routes to the same destination. It acts as a…
