Problems solved by technology

When you need to add a member to the Anycast-RP set, you need to manually add a configuration on all member devices to specify the address of the newly added member, which is a heavy workload and error-prone

Embodiment 1

[0043] In this embodiment, figure 2 Take the diagram in the example as an example. Rendezvous point 1 (RP1), Rendezvous point 2 (RP2), and Rendezvous point 3 (RP3) are the three members in the same Anycast-RP set. The Anycast-RP address released to the outside is Aggregation Point A ( RPA). Rendezvous point 4 (RP4) is a device that wants to join the Anycast-RP set.

[0044] image 3 It is the flow chart of this embodiment. The technical scheme of the present invention is described by taking the joining of the convergence point 4 into the Anycast-RP set as an example, as image 3 As shown, this embodiment includes the following steps:

[0045] Step 301: Device 4 itself is configured as C-RP, and the local address is RP4.

[0046] In this step, if device 4 wants to become an RP, it configures itself as a C-RP (candidate RP), and the Anycast-RP address that it will join in the Anycast-RP set is RPA. Therefore, the Anycast-RP configured by device 4 itself The RP address is RPA, and th...

Abstract

The invention discloses a method and equipment for automatically adding anycast rendezvous point members. The bootstrapping router BSR receives a candidate rendezvous point C-RP notification message sent by a device that intends to become a rendezvous point RP, and the C-RP notifies The message also carries the Anycast-RP address of the Anycast rendezvous point Anycast-RP set that the RP device wants to join, the local address of the RP device, and the range of multicast groups served by the RP device; The Anycast-RP address and the local address are extracted from the C-RP notification message, and the local address is added to the member addresses in the Anycast-RP set corresponding to the Anycast-RP address, and the Anycast-RP set The multicast group range served by the RP device corresponding to the member address of the RP device is the same, and the multicast group range served by the RP device is the multicast group range served by the Anycast-RP set; the BSR sets the Anycast-RP address and the Anycast- All member addresses corresponding to the RP address are added to the BSM message and sent out, so that the device configured with the Anycast-RP address learns from the BSM message and records all member addresses carried by it except itself.

Description

Technical field [0001] The invention relates to network communication transmission technology, in particular to a method and equipment for automatically adding anycast assembly point members. Background technique [0002] In the Protocol Independent Multicast-Sparse Mode (PIM-SM, ProtocolIndependentMulticast-SparseMode) protocol (RFC4601), it is required to select an aggregation point RP for each multicast group to serve for it, and the designated router DR directly connected to the multicast source to the RP to which it belongs Sending registration messages, so that the RP maintains the source information of all the multicast groups it serves, and the receiver can order all the multicast sources of the group by sending a group join to the RP. [0003] Anycast-RP (Anycast-RP) implements a RP redundancy backup and load sharing mechanism, that is, there are multiple RP devices for the same multicast group, but they all use the same Anycast-RP address; first, for multiple devices Con...
