Abstract
A path construction method and related devices are disclosed. The method may include: advertising, by a second PE node, a first VPN route to a first PE node through an MP-BGP signaling channel, such that the first PE node is able to determine a label forwarding path to a first VPN Prefix based on a first transmission path descriptor (TPD) carried in the first VPN route received; where the first TPD is configured to identify the label forwarding path for a first VPN message to reach a BGP next hop.
