Abstract
In one embodiment, a method generally includes identifying at a local Virtual Private LAN Service Provider Edge (VPLS PE) device whether remote VPLS PE devices are configured for operation as a Provider Backbone Bridge (PBB), negotiating pseudowire connections with the remote VPLS PE devices based on identification of the remote VPLS PE device configuration, receiving a frame destined for one of the remote VPLS PE devices, and transmitting the frame in a format compatible with the remote VPLS PE device. The local VPLS PE is configured for operation as a PBB and at least one of the remote VPLS PE devices is not configured for operation as a PBB. An apparatus for use in mixed mode VPLS network is also disclosed.
