Embodiment 1

[0030] The method for processing the multicast forwarding entry in the TRILL network of this embodiment may be performed by an RB in the TRILL network, as image 3 As shown, the method includes the following steps:

[0031] Step S302, receiving the correspondence between the root RB and the VLAN sent by the RB with the highest priority of the tree root, wherein one VLAN corresponds to one root RB;

[0032]Each RB in the TRILL network uses NickName as the tree root priority, sorts the tree root priorities of all RBs, and the RB with the highest tree root priority broadcasts the NickName of the root RB of the multicast tree that all RBs need to calculate . In this embodiment, the RB with the highest tree root priority will also allocate a corresponding VLAN to the root RB of the multicast tree, wherein a VLAN corresponds to a root RB, and the correspondence between the root RB and the VLAN (that is, the root RB The corresponding relationship with the VLAN assigned to the root ...

Embodiment 2

[0047] In the method of this embodiment, when an RB is used as the RB with the highest root priority, the operations that the RB needs to perform also include the following steps:

[0048] Step S402, assigning a corresponding VLAN to the root RB of the multicast tree, wherein a VLAN corresponds to a root RB;

[0049] Step S404, broadcast the correspondence between the root RB and the VLAN, that is, the correspondence between the root RB and the VLAN assigned to the root RB.

[0050] In the prior art, the RB with the highest tree root priority broadcasts the NickName of the root RB of the multicast tree that all RBs need to calculate. In this embodiment, the RB with the highest tree root priority will not only broadcast the NickName of the root RB of the multicast tree that all RBs need to calculate, but also broadcast the correspondence between the root RB and the VLAN assigned to the root RB Broadcast out. In the specific implementation process, the RB with the highest tree...

Embodiment 3

[0060] For the methods in the first and second embodiments above, this embodiment provides an RB in a TRILL network, such as Image 6 As shown, the RB includes the following modules: a receiving module 10 and a computing module 20, wherein:

[0061] The receiving module 10 is configured to receive the correspondence between the root RB and the VLAN sent by the RB with the highest tree root priority, wherein one VLAN corresponds to one root RB;

[0062] Calculation module 20, for calculating the multicast forwarding entry, according to the corresponding relationship between the root RB and VLAN received by the receiving module 10, on each multicast tree, calculate the group of the VLAN corresponding to the root RB of the multicast tree broadcast forwarding entry.

[0063] In addition, when the RB is used as an Ingress RB, the RB may also include: an establishment module for establishing the root RB, VLAN, and multicast MAC of the multicast tree according to the corresponding rel...

Abstract

This application discloses a method for processing multicast forwarding entries in a TRILL network and a routing bridge. The method is applied to a routing bridge RB in a TRILL network. The method includes: receiving the root The corresponding relationship between RB and VLAN, wherein, a VLAN corresponds to a root RB; when calculating the multicast forwarding entry, calculate the root of the multicast tree on each multicast tree according to the corresponding relationship between the root RB and VLAN Multicast forwarding entry of the VLAN corresponding to the RB. The application effectively reduces the number of calculated multicast forwarding entries and saves entry resources.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a method for processing multicast forwarding entries in a TRILL network and a routing bridge. Background technique [0002] As the number of servers and switches continues to increase, the data center network is increasingly inclined to a flat network architecture for easy maintenance and management, which requires the construction of a large Layer 2 (Layer 2, L2) network. The traditional Layer 2 network uses the Spanning Tree Protocol (STP) to eliminate loops. However, some inherent defects of the STP itself make it no longer suitable for data center networks, such as: [0003] (1) The spanning tree protocol eliminates loops by blocking redundant links, but the data center network cannot bear this bandwidth waste; [0004] (2) The spanning tree protocol requires that all data must be forwarded through the root bridge, which will affect the forwarding eff...
