<Jeremy's IT Lab> Day 25: RIP & EIGRP

RIP & EIGRP RIP:-> max hop count 15-> update every 30mins-> msg type: response / request (1) RIPv1 (not use): -> only advertise classful adrs(class A, B, C..) -> doesn't support VLSM, CIDR (subnet) -> msg broad cast (2) RIPv2: -> doesn't support VLSM, CIDR (subnet) -> msg multi cast (send specific group) 224.0.0.9> EIGRP:-> advanced ver-> Cisco only-> no limitation ..

<Jeremy's IT Lab> Day 24: Dynamic Routing

Dynamic Routing: find best destination dynamically-> advertise info about route they know to other Router-> form adjacent router to exchange info-> determines superior route (lowest) Types of Dynamic Routing / Algorithm type:- IGP(Interior Gateway Protocol) : within single Autonomous System (AS), single organization(e.i. company) 1. Distance Vetor (1) RIP (Routing Information Protocol) ..

Ethernet Channel prob: oversubscription (speed lower, can't use multi interface because of STP)sol: Ether channel (= Port channel , = LAG(link aggregation group))=> multiple interface to act single interface, treat this group as single interface - PAgP(Port Aggregation Protocol) -> IEEE 082.3ad- LACP(Link Aggregation Control Protocol) -> Cisco=> PAgP & LACP Dynamically negotiate create/maintena..

RSTP * Spanning Tree VersionsIEEECiscoSpanning Tree Protocol (802.1D)- All VLANs share one STP instance- cannot load balancePer-VLAN Spanning Tree Plus(PVST+)- Each VLAN has its own STP instance- can load balanceRapid Spanning Tree Protocol (RSTP, 802.1w)- much faster than 802.1D- All VLANs share one STP instance- cannot load balanceRapid Per-VLAN Spanning Tree Plus(Rapid PVST+)- Each VLAN has i..

STP (Spanning Tree Protocol)- classic STP (802.1D - IEEE)- rapid STP Reason of using STP:Prob1: Broadcast Storms- Switches connected redundancy as security, switches forward infinitely broadcasting frames through trafficProb2: MAC Address Flapping- Also switch use source MAC address field to 'learn' MAC and update its table as much as they can STP:-> Prevents loop in bridged NW-> all vendor's sw..
