\n\n# Configuração e start no switch:
\nUma vez configurados, acessar o terminal de cada um dos hosts para configuração de rotas, forçando o tráfego a passar pelo container switch.
\nSeguindo o exemplo do script acima:\nNo switch 1:
\nroute add -net 192.168.2.3 netmask 255.255.255.255 gw 192.168.1.2
\n

\nNo switch 2:
\nroute add -net 192.168.1.1 netmask 255.255.255.255 gw 192.168.2.2
\n

\nNo switch:
\nAcessar o container para execução do switch bmv2 com o código p4 compilado. Para o exemplo acima, iniciar como:
\nsimple_switch --log-console -i 1@veth2 -i 2@veth3 standard.json\n

\nO arquivo standard.json é um exemplo de um programa p4 compilado simples, está disponível em:
\nhttps://github.com/dnredson/geradoresDeTrafego/blob/main/standard.json
\nPara compilar seu próprio código P4, utilize o container p4c https://hub.docker.com/r/p4lang/p4c . Em breve, o compilador será incorporado ao P4D.
\n\nCaso deseje adicionar entradas na tabela de roteamento através do controlador do switch, acesse o terminal do container e inicie o client do bmv2:
\nsimple_switch_CLI\n\nadicionar as entradas, no scrip acima, o exemplo seria:
\ntable_add MyIngress.ipv4_lpm ipv4_forward 192.168.2.3 => 00:00:00:00:02:02 2
\ntable_add MyIngress.ipv4_lpm ipv4_forward 192.168.1.1 => 00:00:00:00:01:01 1\n\n\nDesta forma, o ambiente está configurado.\n
\n# Script para limpeza do ambiente conforme o exemplo dado acima:
