Comparing Distance Vector Routing to Link State Routing
Distance Vector
Link State
Views net topology from neighbor perspective
Gets common view of entire network topology
Increments metrics as an updates: slow convergence
Calculates the shortest path to other routers
Frequent, periodic updates
Event triggered updates: faster convergence
Passes copies of routing table to neighbor routers
Passes link state routing updates to other routers
IP RIP updates occur every 30 seconds
IPX RIP updates occur every 60 seconds
SAP up dates are sent every 60 seconds
Inverse ARP updates every 60 seconds
Frame Relay Serial CDP packet every 60 seconds
CDP hold time is 180 seconds
IGRP Sends regular routing update every 90 Seconds
IGRP Admin distance 100
RIP Admin distance 120
Update Timers 90 second updates
Hold-Down Timer 190 seconds
Protocols within an AS
OSPF
VLSM (Variable Length Subnet Mask)
EIGRP
IGRP 3 types of routes: (they use D-V and hop counts)
