Abstract

The present invention provides a method and device for tunnel convergence. The method includes: a leaf node of a label forwarding path tunnel sends a label mapping message without an MBB label to an upstream node currently updating the inactive state on the first link, and the label The mapping message is used to indicate that the upstream node ends in the MBB notification message waiting state, the leaf node sets the upstream control block in the inactive state as the upstream control block in the activated state, and the leaf node sends forwarding information through the first link, Solve the problem of slow convergence of mLDP tunnels in MBB scenarios, and realize fast convergence of mLDP tunnels.

Description

technical field [0001] The present invention relates to the communication field, in particular to a tunnel convergence method and device. Background technique [0002] The multicast virtual private network (Virtual Private Network, referred to as VPN) is an existing Border Gateway Protocol (Border Gateway Protocol, referred to as BGP) / Multiprotocol Label Switching (Multiprotocol LabelSwitching, referred to as MPLS) IP VPN basis A technology that supports multicast services. This technology encapsulates private network multicast packets and transmits them through multicast tunnels established between network segments to complete the transmission of multicast data between private networks. [0003] The main problem solved by the multicast VPN technology is how to check the reverse path forwarding (Reverse Path Forwarding, referred to as RPF) on the public network without knowing the route of the private network to achieve the purpose of forwarding multicast data, private netwo...
