Abstract

The invention provides a message processing method and device, and the method is applied to first PE equipment, and comprises the steps: receiving a first EVPN route notification transmitted by secondPE equipment, and the first EVPN route notification comprises the address information of CE equipment, a first route mark, and a first Ethernet segment identification ESI value; when the first routing mark is the first value and a second ESI value the same as the first ESI value exists, sending a second EVPN routing announcement, the second EVPN routing announcement comprising address informationof the CE device and the second routing mark; wherein the second routing mark is marked as a second value, and the second routing mark is used for indicating that the address information of the CE equipment included in the second EVPN routing notification is the address information of non-local learning; wherein the ESI value is used for representing that the CE device accesses a link of the PE device.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a message processing method and device. Background technique [0002] At present, in order to improve the high reliability of the access side, for the Ethernet virtual private network (English: Ethernet Virtual Private Network, referred to as: EVPN) networking, the EVPN protocol stipulates multi-homing access networking, which can be better used for the EVPN protocol. Ensure the reliability of service data packets. [0003] Such as figure 1 As shown, a virtual machine (English: Virtual Machine, referred to as: VM) 1 is a multi-homing host, which simultaneously accesses two VXLAN tunnel end point (VXLAN Tunnel End Point, referred to as: VTEP) devices through an integrated access switch (LSW), They are VTEP1 equipment and VTEP2 equipment respectively, and VM2 is connected to remote VTEP3 equipment. VM1 sends address resolution protocol (English: Address Re...
