Ex3 Chapter 1 - LAN Design
Hierarchical network design (Cisco) model involves dividing the network into discrete layers. Each layer provides specific functions that define its role within the overall network.
The typical hierarchical design model is broken up in to three layers:
- access,
- distribution,
- core.

Thing to repeat and remeber:
- poison reverse (default)
- split horizon http://www.ietf.org/rfc/rfc1058.txt
- eigrp discovery proccess
- rip updates (version in updates)
- routing protocols on which layer works
- BD/BDR election, election after fail
- classless/classfull packet flow in routing decision
- summarization
- discontiguos networks
Habits of Highly Effective Students
"What is the best way to study for a Certification Exam?"
This is probably the most common question I get asked by Network Academy students and peers chasing Cisco Certifications. While there is no concrete answer that works for everyone, there are some really great pieces of advice that I have heard throughout the years, and implemented in my daily study routine.
Ex2 Chapter 12 – BGP basics
The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It maintains a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional Interior Gateway Protocol (IGP) metrics, but makes routing decisions based on path, network policies and/or rulesets.
Routers use “routing protocols” to exchange routing information with each other.

Ex2 Chapter 10 – Link-State Routing Protocols
Distance vector routing protocols are like road signs because routers must make preferred path decisions based on a distance or metric to a network.
Link-state routing protocols take a different approach. Link-state routing protocols are more like a road map because they create a topological map of the network and each router uses this map to determine the shortest path to each network.
