# Trabalho prático 7 - OSPF
# Considere o seguinte cenário de rede:
Baixar arquivo - packet tracer
Considere que dispões da fede 192.168.0.0/16 para atribuir às redes locais e a rede 10.1.1.0/24 para atribuir à ligações entre os routers. Cada uma redes locais derá suportar 200 hosts ligados.
Implemente o cenário no simulador e configure os equipamentos.
