| 发明名称 | Bootstrapping fault detection sessions over a P2MP tunnel | ||
| 摘要 | A method for detecting faults associated with a tunnel delivering multicast traffic from a source provider edge router (PE) to each of a plurality of destination PEs, the method using a routing protocol such as BGP to communicate route information to destination PEs, and a fault detection protocol such as BFD to detect tunnel faults. | ||

| 主权项 | 1. A method for detecting faults associated with a tunnel delivering multicast traffic from a source provider edge (PE) to each of a plurality of destination PEs, the method comprising: transmitting, from the source PE toward each destination PE via a routing protocol, information identifying the source PE and the tunnel delivering multicast traffic to the destination PEs; establishing a Bidirectional Forwarding Detection (BFD) session between the source PE and the destination PEs; using the transmitted information as a BFD session discriminator at one of the destination PEs to associate the BFD session with the tunnel at the one of the destination PEs; and defining data plane faults detected by the BFD session as faults of the tunnel. | ||
