Provided is a method and device for implementing Virtual Private Network (VPN) cross-domain, and a border node. The method includes that: a border node receives a advertisement message which carries VPN route information and is sent by a first node to a second node, wherein the border node supports Internet Protocol Version 6 Segment Routing (SRv6) capability, and the first node and the second node belong to different domains; and the border node assigns VPN identity information to a VPN route corresponding to the VPN route information, adds the VPN identity information into the advertisement message and sends the advertisement message to the second node, wherein the VPN identity information includes at least one of: a VPN Segment ID (SID) and a VPN label.
