Abstract

The present application provides a multicast entry management method, device, device and machine-readable storage medium. The method includes: receiving a first route notification message sent by a second PE device, the first route notification message including the group to which the CE device belongs The address information of the multicast group, the first multicast protocol version identifier, and the first priority; if there is a multicast entry corresponding to the address information of the multicast group, and the first multicast protocol version identifier is the same as the first multicast entry in the multicast entry The two multicast protocol version identifiers are different, then compare the first priority with the second priority in the multicast entry; if the first priority is better than the second priority, use the first multicast protocol version identifier and The first priority replaces the second multicast protocol version identifier and the second priority in the multicast entry. Through the technical solution of the application, errors in the multicast protocol version identification can be avoided, the multicast entry is correct, the multicast protocol version identification of the multicast entry is updated correctly, and user experience is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method, device, device and machine-readable storage medium for managing multicast entries. Background technique [0002] EVPN (Ethernet Virtual Private Network, Ethernet Virtual Private Network) is a Layer 2 VPN (Virtual Private Network, Virtual Private Network) technology, and the control plane adopts MP-BGP (MultiProtocol-Border Gateway Protocol, Multi-Protocol-Border Gateway Protocol) notification For routing information, the data plane adopts VXLAN (Virtual Extensible Local Area Network, extensible virtual local area network) encapsulation method to forward packets. Among them, VXLAN is a layer-2 VPN technology based on IP network and adopts "MAC (Media Access Control, Media Access Control) inUDP (User Datagram Protocol, User Datagram Protocol)" encapsulation form. VXLAN can provide Provider or enterprise IP network, provide Layer 2 interconnection f...
