A BGP-VPWS service can benefit from dual-homing, as described in IETF Draft draft-ietf-bess-vpls-multihoming-01. When using dual-homing, two PEs connect to a site, with one PE being the designated forwarder for the site and the other blocking its connection to the site. On failure of the active PE, its pseudowire, or its connection to the site, the other PE becomes the designated forwarder and unblocks its connection to the site.
