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 multicast in a VRRP network environment, by carrying a virtual IP address when sending a PIM Hello message on an interface enabled with VRRP, and using VRRP when receiving the PIM Hello message The establishment of PIM neighbors with virtual IP addresses can enable unicast and multicast services to be active and standby at the same time in the VRRP network environment. At the same time, it is fully compatible with the current RFC protocol, which solves the problem that VRRP and multicast cannot be deployed at the same time. At the same time, it also discloses a device for realizing PIM multicast in a VRRP network environment, including a sending module and a receiving module. The router of the packet establishes a PIM neighbor relationship with a real address or a virtual IP address. The invention has simple protocol and flexible deployment, can realize the co-deployment of VRRP and multicast, and allows active and standby of unicast and multicast 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...
