27 – ROuting Protocol Concept
===============================
RIP
– Ford Pinto
– it’s not gonna be fast or smooth or quick but work well from point a to point b no care the car looks like
– A default Advertise 30 sec <–Hello time (advertimese timer )
– 90 sec sebelum router menentukan sebelahnya mati, (hold) memberikan waktu to recovery but COST
– metric = is how to routing protocol to figure out the best to REACH destination
(HOP Count) next Router
don’t care the BANDWitdh IT’s CRAZY
Support everywhere
cisco think RIP is terrible Protocol, we can do better
==================================================================================
Improve RIP with IGRP
IGRP improve metric, hop, delay and speed
Hello 90 sec
Delay 270
IGRP is DEAD
=================================================================================
OSPF most Popular protocol in the world
Corvete
– Default Hello Timer 10 sec
– beauty of ospf
– metric = COST = BANDWITDH
====================================================================================
IS – IS
compatator to OSPF
TCP/R
OSI BETA
is – is was routing protocol OSI better than OSPF (because politik and mafia)
=============================================================================
EIGRP
A Ferrari
CISCO to CISCO ( Priopetary )
Good Speed
Really easy to configure
equal load balancing
GREAT Metric = BW + Delay + Realible + Load + MTU ( K-formula)
Routing Technology :
EIGRP
Eigrp Overview
Eigrp = Enhanced Interior Gateway Routing Protocol
* Sussessor dari IGRP
* CIsco Proprietary “Hybrid” Protocol Hybrid = gabungan dari DV & LS
* Both DV & Link state behaviour
* Really “Advance Distance vector”
Classless Protocol
* Membawa Subnet mask dan Support VLSM and Summarization
knp harus menggunakan EIGRP ?? kalau kita meng-design network
Eigrp memilih bedasarkan jalur ?
Eigrp = BW = bandwitdh terbesar
Delay = by defalut Router 100ms
Load
Reliability
Fast Convergence:
lebih cepat
Active Backup-Route = dimana kalau ada link putus jalur akan di belokan tanpa harus re-kalkulasi ulang
Eigrp = mengunakan multicast dengan menggunakan 224.0.0.10
====================================================================================================
BGP = Border Gateway Protocol
Router protocol for INTERNET dimana banyak Handle thousand router
BGP = > ISP / Enterprise
=====================================================================================================
dapatkan router menjalankan multiple routing protocol pada saat bersamaan ? YES
Administrive Distance adalah above the matric how believable is run protocol
LOWER NUMBER (Administatviv Distance ) is BETTER maksudnya bila ada multiple routing protocol,
semua kan cara penghitungannya berbeda2 dimana Eigrp menting dengan cost, bw+delay+mtu
dan rip menghitung dengan Hop count
jadi untuk menjalankanya dan mana yang di pilih adalah diliat dari Administattive distancenya
==============================
Eigrp – 90
OSPF – 110
IGRP – 100
BGP – 20
Static – 1
IS – IS – 115
================================
Static = cost = 0 is directly connected interface
