Laboratório de Redes II

Considerações:

• As portas não mencionadas no mapa estão em VLAN 2 e modo acesso.
• Os cabos estão descritos ao lado dos enlaces, e entre parênteses as VLANs.

• Legenda:
  • Enlace vermelho: modo trunk.
  • Enlace verde: modo trunk com roteamento entre VLANs.
  • Enlace azul: modo acesso.
