Abstract
A method, apparatus and computer program product for efficiently transmitting tunnel keep-alive messages is presented. A tunnel keep-alive trigger message is provided from a control processor of a multi-processor network switching device to at least one forwarding engine of the network switching device. The at least one of the forwarding engines produces a tunnel keep-alive packet as a result of receiving the tunnel keep-alive trigger message from the control processor. The at least one forwarding engine forwards the tunnel keep-alive packet on all tunnels the forwarding engine is servicing.
