Embodiment 1

[0062] Figure 1a It is a flow chart of the route update method in Embodiment 1 of the present invention. Such as Figure 1a As shown, the routing update method may include:

[0063] Step 101, the DRB (Designated Routing Bridge) receives the AF status report message from the routing bridge of the TRILL network through the AF (Designated Forwarder) channel, and the AF channel is the routing bridge established according to the channel mechanism of the TRILL protocol and the message channel between the DRB, the AF status report message is used to instruct the first routing bridge to change from the AF of the VLAN (Virtual Local Area Network) to a non-AF, and the VLAN is accessed through the STP (Spanning Tree Protocol) network TRILL (Transparent Interconnection of Multiple Links) network.

[0064] Specifically, since there is great resistance to modifying the traditional ISIS protocol and the HELLO protocol, the embodiment of the present invention may not change the AF designa...

Embodiment 2

[0073] Figure 2a It is a flow chart of the route update method in Embodiment 2 of the present invention. Figure 2a and Figure 1a The steps with the same label have the same meaning, and the difference from the previous embodiment mainly lies in: as Figure 2a As shown, before step 101, the routing update method may also include:

[0074] Step 201, electing the DRB;

[0075] Step 202, the AF channel is established between the DRB and other routing bridges in the TRILL network, and the other routing bridges are routing bridges in the TRILL network except the DRB.

[0076] In a possible implementation, after step 101, if the second condition is met, according to the AF status report message, it can be determined that the AF of the VLAN needs to be switched from the first routing bridge to the second routing bridge, and the DRB passes The step of sending, by the AF channel to the second routing bridge, a specified message for indicating the time to eliminate suppression may...

Embodiment 3

[0084] image 3 It is a flow chart of the route updating method according to the third embodiment of the present invention. Such as image 3 As shown, the routing update method may include:

[0085] Step 301: Send an AF status report message to the DRB (designated routing bridge) of the TRILL network through the AF (designated forwarder) channel, the AF channel is the routing bridge and the routing bridge established according to the channel mechanism of the TRILL protocol The message channel between the DRBs, the AF status report message is used to instruct the first routing bridge to change from the AF of the VLAN (Virtual Local Area Network) to a non-AF, and the VLAN accesses TRILL through the STP (Spanning Tree Protocol) network (multi-link transparent interconnection) network.

[0086] Since there is great resistance to modifying the traditional ISIS protocol and the HELLO protocol, the embodiment of the present invention may not change the AF designation process. DRB...

Abstract

The present invention relates to a routing updating method and routing equipment, wherein the routing updating method includes: a designated routing bridge DRB receives an AF status report message from a routing bridge of a TRILL network through a designated forwarder AF channel, and the AF channel is According to the message channel between the routing bridge and the DRB established by the channel mechanism of the TRILL protocol, the AF status report message is used to instruct the first routing bridge to change from the AF of the virtual local area network VLAN to a non-AF, the The VLAN accesses the multi-link transparent interconnection TRILL network through the Spanning Tree Protocol (STP) network. The RB reports to the DRB whether it is still the AF of a certain VLAN through the AF channel. The DRB can quickly detect the change of the AF status, which improves the network convergence speed in the TRILL‑STP hybrid networking scenario.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a routing updating method and routing equipment. Background technique [0002] Ethernet uses STP (Span Tree Protocol, Spanning Tree Protocol) at the data forwarding layer. STP is a data link layer (layer 2) communication protocol based on OSI (Open System Interconnect Reference Model, Open System Interconnect Reference Model). STP can generate a tree from the network topology, avoid network loopback in the LAN, and solve the "broadcast storm" problem in the ring Ethernet network. As a network protection technology, STP can eliminate loop connections caused by mistakes or accidents. But STP has obvious disadvantages, for example: (1) STP prevents loops by blocking certain ports, does not allow multipath routing (multipath routing), all traffic is spread on a tree, even if there is an idle link It cannot be used either, and the bandwidth is not fully utilized; (2) ...
