CCNA 정리자료1. Update time & Hold time

RIP - 30', 180'
CDP - 60', 180
IGRP- 90',
IPX RIP - 60' , SAP - 60'
IARP-60' , LMI-10'

2. Roting Protocol
1)RIP - hop count(Max=15), classful routing protocol(not send the subnetmask along with the routing updated)
2)IGRP - Bandwidth, Delay, Loading, MTU, Reliability(Max=255)
3)IPX RIP - ticks(about 1/18 sec.), hop count(Max=15)
