Abstract
In general, techniques are described for decapsulating and forwarding VPLS frames in a hybrid PE router space. In one example, a method includes sending a first control plane message that includes first configuration information to a first PE router, the first control plane message comprising a request that the VPLS frames include a control word when forwarded to the first PE router. The first PE router may receive from a second PE router a second L3 control plane message that includes second configuration information for forwarding VPLS frames to the second PE router, the second L3 control plane message not comprising a request to include the control word when forwarded to the second PE router. The method may include configuring a forwarding plane of the first PE router to process VPLS frames that are received from the second PE router without processing the VPLS frames to remove the control word.
