Use Cases for Dynamic Profiles for VPLS Pseudowires

A dynamic profile is a set of characteristics, defined in a type of template, that you can use to provide dynamic subscriber access and services for broadband applications. These services are assigned dynamically to interfaces. You can use dynamic profiles to configure the VLAN parameters of the dynamic interfaces on MX Series routers.

Two use cases for configuring VPLS pseudowires with dynamic profiles are:

• Configuring an extra VLAN tag onto pseudowire traffic — This is a common scenario where all the traffic received from a customer edge (CE) interface needs an additional VLAN tag toward the core. In such cases, you can use dynamic profiles at ingress and egress to control the pseudowire behavior. You can apply dynamic profiles to receive the desired frames, set the additional VLAN tag for these frames, and send these tagged frames with the desired VLAN identifier.

• Configuring a VPLS pseudowire as a trunk interface — This is another common scenario where the requirement is to accept traffic from a particular source and to route the traffic based on specific criteria. Dynamic profiles can be used to create multiple pseudowire trunk interfaces to accept the traffic based on specific VLAN identifiers, and to route the accepted traffic to the desired destination.
