Aquí hay algunos ejemplos de tipo 4 y tipo 5

SVC VPWS
Un VPWS SVC es un VPWS estático, que no requiere un protocolo de señalización, sino etiquetas VC configuradas para transmitir información L2VPN.

***********************************************************************

CE1 y CE2 se conectan a PE1 y PE2, respectivamente; PE1 y PE2 están conectados en una red troncal MPLS.
Se requiere un LSP para configurar un VPWS SS-PW dinámico entre PE1 y PE2.

Ejemplo para configurar la conmutación dinámica VPWS
En ambos extremos de un PW de conmutación, se configuran dos PW dinámicos. Los PW dinámicos usan LDP extendido para transmitir información de capa 2 y etiquetas de VC.

Ejemplo para configurar la encapsulación de paquetes de protocolo de capa 2 en un VPWS PW

CE1 y CE2 son dispositivos que no son de Huawei. Ambas CE admiten el Protocolo de descubrimiento de Cisco (CDP). Para garantizar que estos EC puedan funcionar con NE20E, debe establecer un VPWS PW entre PE1 y PE2. De esta manera, CE1 y CE2 pueden transmitir de manera transparente los paquetes CDP entre ellos a través del PW y usar el CDP para descubrirse entre sí.
