"Cisco VPLS does not require the exchange of reachability information via a signaling protocol. This information is learned from the data plane using standard address learning, aging and filtering mechanisms defined for ethernet bridging."
VPLS or Virtual Private LAN Service is a VPN technology that enables Ethernet multipoint services (EMSs) over a packet-switched network infrastructure. VPLS helps extend the reach of Ethernet further to be used as a WAN technology. As VPLS works over Ethernet the information for reachability is sourced via the normal Ethernet protocols and hence it doesn't require a mechanism of its own.
