MPLS LAB : L2L - Tunel L2 entre dos PE ( LAN TO LAN Bridge)

Escenario:
Red MPLS

Solicitud:
El cliente requiere conectar dos de sus sedes con un Lan-to-Lan (bridge).
la red del cliente es la 10.168.0.0/24

Topología

Para configurar (mpls l2transport)

1. Configurar la interfaz o sub-interfaz con  mpls l2tranport route o xconnect
   Se puede utilizar :
   mpls l2trasport router 192.168.255.222 100  ó
   xconnect 192.168.255.222 100 encapsulation mpls
2. Para el tuenl se puede utilizar una loopback o una interfaz, estas ip deben tener conectividad.
