Title:
PACKET TRANSMISSION METHOD, PROVIDER EDGE DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/120233
Kind Code:
A1
Abstract:
Provided are a packet transmission method, and a provider edge device and system. The method comprises: a first PE receiving a first routing message from a first gateway, wherein the first routing message comprises an address of a first VM, a first VNI, and an IP address of the first gateway, wherein the first VNI identifies a first portion of a broadcast domain, the first portion comprising the first VM; transferring the first VNI and an IP address of the first VXLAN tunnel endpoint VTEP in the first routing message to a first extension portion of the first routing message, adding a first MPLS label allocated to a second PE to the first routing message, and adding an IP address of the first PE to the first routing message, so as to obtain a second routing message; and sending the second routing message to the second PE. After a second routing message is obtained, the second PE can perform an overlay operation, and the first PE does not need to perform an overlay operation, thereby reducing performance requirements on the first PE.
