Configurar VLAN Trunks y Routing Cisco

Packet Tracer 7

1.- En todos los Switches de Valencia, configurar Trunk utilizando trunk encapsulation, y asegúrese de que el trunk no se convierta dinámicamente en un puerto de acceso.

2.- Crear VLANs 10 (STATIC) 10.16.0.0/24, 20 (VoIP) 10.16.2.0/24, 30 (PUBLIC) 10.16.4.0/23, 40 (CLIENT) 10.16.6.0/23 en todos los Switches manualmente o utilizando VTP.

3.- Limitar todos los Trunks para llevar sólo VLANs 1, 10, 20.

4.- Configurar R1-AS como un Router on a Stick (ROAS) que proporcione enrutamiento entre clientes en VLAN 10 y VLAN 20.
