Abstract

The invention discloses a LISP-based multicast realization method and equipment, the method comprising: after enabling the BSR proxy function, the tunnel router sends a registration message to the MS, and the registration message carries the BSR enabled tunnel router The information of the proxy function; when the tunnel router receives the first self-report message, it sends the first self-report message to the MS; the tunnel router receives the second message from other tunnel routers forwarded by the MS. A self-report message, using the address information carried in the second self-report message to generate a first (EID, RLOC) mapping table. In the embodiment of the present invention, the transmission of the PIM SM protocol message across the LISP network can be realized, the LISP multicast function can be realized under the condition that the ITR / ETR does not know the multicast source address, and the LISP network can be effectively supported.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a LISP-based multicast realization method and equipment. Background technique

[0002] Such as figure 1 As shown, it is a schematic diagram of LISP (Location / ID Separation Protocol, Location and Identity Separation Protocol) network. The LISP network will divide the network IP address into EID (Endpoint ID, terminal identification) and RLOC (Routing Locator, routing location ). Among them, the EID-to-RLOC mapping relationship will be introduced into the LISP network. The EID is used to identify the host and does not have the global routing function, and the RLOC is used for the entire network routing. In a LISP network, an IPv4 or IPv6 host only identifies its ID, and its location is identified by an ITR (Ingress Tunnel Router, tunnel entry router) / ETR (Egress Tunnel Router, tunnel exit router). The LISP network includes a data plane and a control plane. The data plane i...
