Problems solved by technology

[0013] The purpose of the present invention is to provide a method for realizing PIM multicast in a VRRP network environment, so as to solve the problem that the downstream device uses the virtual IP address of VRRP as the next link to the upstream route when the multicast PIM protocol and the VRRP protocol are applied simultaneously. When hopping, multicast services cannot deploy applications

Embodiment Construction

[0033]The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0034] by figure 1 For example, usually the downlink device Router-A adopts the virtual IP address 1.1.1.1 as the next hop of the route in order to realize the unicast active / standby. figure 1 In the network application shown above, VRRP and multicast are deployed. In the current implementation of the protocol, multicast can only support the establishment of multicast neighbors with real addresses and the sending of PIM join and prune messages. 1.1.1.1 related neighbor entries, so the deployment of the multicast service in the network shown in the figure will fail.

[0035] In this case, consider treating the virtual IP address as a real address, and use the virtual IP address to establish a PIM neighbor relationship. After Router-A...

Abstract

The invention discloses a method for realizing PIM (Protocol Independent Multicast) in a VRRP (Virtual Router Redundancy Protocol) network environment. A virtual IP (Internet Protocol) address is carried when a PIM Hello message is transmitted to an interface for enabling the VRRP; when the PIM Hello message is received, the virtual IP address of the VRRP is used for establishing a PIM neighbor, so that unicast and multicast services can be simultaneously used as a host and a backup in the VRRP network environment. Meanwhile, the virtual IP address of the VRRP is completely compatible with a current RFC (Request for Comments) protocol, and so that the problem that the VRRP and the multicast cannot be deployed simultaneously at present is solved. The invention also discloses a device for realizing the PIM multicast in the VRRP network environment. The device comprises a transmitting module and a receiving module, wherein the transmitting module is used for transmitting the PIM Hello message carrying the virtual IP address; and the receiving module is used for receiving the PIM Hello message and selecting and transmitting a router of the PIM Hello message to establish the PIM neighbor by using a real address or the virtual IP address. The method and the device disclosed by the invention have the characteristics that the protocol is simple and the deployment is flexible; common deployment of the VRRP and the multicast can be realized; and the host and backup of the unicast and the multicast can be allowed at the same time.

Description

technical field [0001] The invention relates to the technical field of multicast communication, in particular to a method and device for realizing protocol-independent multicast (PIM) multicast in a virtual router redundancy protocol (VRRP) network environment. Background technique [0002] Current network applications require network devices not only to provide data forwarding capabilities provided by traditional routers and switches, but also require network devices to support various applications, such as traffic cleaning, traffic statistics, virus detection and other functions. However, it is difficult for any independent technology manufacturer to provide all the services required by customers at the same time, so an open application architecture (OAA) can integrate equipment and software produced by many different manufacturers to work like a single device, providing customers with Provide an integrated solution. In the OAA system, from the perspective of hardware str...
