MEMORY DUMP BEFORE EVERYTHING MOVES TO 200-310

CISCO IIN - Intelligent Information Network

SONA - Service Oriented Network Architecture
1. Network Infrastructure (Enterprise Architecture, Servers, Storage, Clients)
2. Interactive Services
3. Applications

PPDIOO 
Plan
Prepare
Design

Operate
Optimize

Hierachy Network 
1. Core Layer - speed, realiability, fault tolererance, QOS, finite
2. Distribution Layer - 20/80, security
3. Access Layer - high availability, broadcast control, port security, arp, vacl

CISCO Enterprise Architecture Model
1. Enterpise Campus
2. Enterpise Edge
3. Enterpise WAN
4. Enterpise Data Center
5. Enterpise Branch
6. Enterpise Teleworker

1. Enterpise Campus
- Campus Core, Bldg Distribution, Bldg Access, Edge Distribution, Server Farm
2. Enterpise Edge
- E Commerce, Intenet / DMZ , VPN Remote Access, Enterprise WAN
3. Enterpise Service Provider
- Internet, WAN Services, PSTN / VOIP

Remote Modules
1. Enterprise Branch - Site to site VPN
2. Enterprise Data Center - High speed LAN
3. Enterprise Teleworker - Remote VPN Access

High Availability
1. Work Station to Router
- Proxy Arp - Router responses for the client/workstation (X)
- Explicit Configuration - multiple GWs (X)
- IRDP - ICMP router discovery protocol (X)
- RIP - enable RIP on workstation level (X)
- HSRP - 1st hop redundancy; VDG -- active and slave
- VRRP - 1st hop redundancy; can use SW IP -- master and slave
- GLBP - 1st hop redundancy; Active Virtual Gateway to Client to Active Virtual Forwarders (RR)
2. Route Redundancy
- Load Balancing
- Increase Availability; PMP Communication Formula = n(n-1)/2
3. Media Redundancy
- STree
- Floating Static Routers - backup link higher admin distrance for WAN
- Channel Aggregation - ether-channel
4. Server Redundancy
- NLB

Network Management
F-ault; detect,proactive cathing
C-onfiguration; implement tracking changes
A-ccounting; track who is using, how freaquent
P-erformance; relaibile, monitor links
S-ecurity; appropriate security

1. SNMP -- v1.0, v2.0/2c and v3 (AuthPriv = authentication and encryption)
2. RMON -- RMON1 (L1 and L2) RMON2 (L1 to L7)
3. Netflow -- (1) Network Accounting (2) Flow Collector (3) Data Analyzer
4. CDP -- L2 Dependency, interface (#no cdp enable) device (#no cdp run)
5. Syslog -- Severity levels 7,6,5,4,3,2,1,0
