The document discusses the configuration of VLANs on switches and subinterfaces on routers to support both IPv4 and IPv6 routing. VLANs allow logical separation of IP networks on a single physical switch. Subinterfaces on routers assign unique IP addresses, subnets, and VLAN associations to support multiple logical networks on a single physical interface. Example configurations are provided for switches to assign ports to VLANs 10, 20 and 30 and for routers to configure subinterfaces with IPv4 and IPv6 addresses for VLANs 10, 20, 30 using RIP and RIPng routing protocols.

Vlans en Switches, Subinterfaces en Routers
Configuración:
RIP y RIPng, IPv4 e IPv6.
Vlans :
- ¿Qué son?
Una VLAN es una subred IP lógicamente separda.
- ¿Para que sirven?
Las VLANs permiten la existencia de varias redes y subredes IP en la misma
red conmutada.

Subinterfaces:
- ¿Qué son?
Las Subinterfaces son interfaces virtuales software que están asignadasa
interfaces físicas.
- ¿Para que sirven?
Cada una de las interfaces está configurada con su propia dirección ip ,
máscara de subred y una única asignación de VLAN, lo que
permite que una interfaz física forme parte de múltiples redes lógicas
simultáneamente.
