Redes de Computadores Aula Prática - Algoritmos de Roteamento Prof. Luiz
Objetivo ● Analisar o funcionamento dos algoritmos RIP (Routing Information Protocol) e IGRP (Internet Gateway Routing Protocol) utilizando o simulador NetSim
Topologia Eth0: /24 Eth0: /24 Eth0: /24 Eth0: /24 S0: /30 S0: /30
Configuração ● Serial 0 em Router1 Router> enable Router# config t Router(config)# hostname router1 router1(config)# int serial 0 router1(config-if)#ip address router1(config-if)# encapsulation ppp router1(config-if)# clock rate router1(config-if)# no shut router1(config-if)# exit
Configuração ● Ethernet 0 em router1 Router> enable Router# config t router1(config)# int ethernet 0 router1(config-if)#ip address router1(config-if)# no shut router1(config-if)# exit router1# copy run start
Configuração ● Configuração do IP ipconfig /ip ipconfig /dg
Configuração ● Router2 – Idem Router 1 com os devidos IPs
Teste ● Ping – pc1 para router1 – Router1 para router2 – Pc2 para router2 – Router2 para router1 ● Tabela de roteamento – Em router1#: show ip route – Em router2#: show ip route
Definição das Rotas ● Estáticas – Em router1: ip route – Em router2: ip route – Teste Router1#: ping Router1#: ping
Definição das Rotas ● Com RIP router1> enable router1# config t router1(config)# router rip router1(config-router)#network router1# show ip route router2> enable router2# config t router2(config)# router rip router2(config-router)#network router1# show ip route
Definição das Rotas ● IGRP router1> enable router1# config t router1(config)# router igrp 10 router1(config-router)#network router1# show ip route router2> enable router2# config t router2(config)# router igrp 10 router2(config-router)#network router2# show ip route Número do AS Apenas roteadores no mesmo AS trocam Rotas
Exercício ● Fazer com RIP
