DESAFIO OSPF NIVEL 1

Bom, vamos para um lab simples de OSPF

Sua tarefa estara completa quando:

1 - O CEA e o CEB estiverem com 1 vizinhança OSPF, e os PEA e PEB com 2 vizinhanças OSPF estabilizadas:

2 - o CEA estiver ecebendo o anuncio 172.40.0.0/24 do CEB (e pingando)

3 - o CEB estiver ecebendo o anuncio 172.10.0.0/24 do CEA (e pingando)

Topologia:
