Embodiment 1

[0030] The method for controlling MAC address information in the EVI network in the embodiment of the present application may be performed by any ED. Such as figure 2 As shown, the method includes the following steps:

[0031]Step S201, receiving a notification message sent by the first ED in the EVI network (an ED of any other site network in the EVI network), wherein the notification message carries network identity information and MAC address information, and the network identity The information is used to indicate the identity of the network to which the ED that sent the announcement message belongs to, and the identity can be the network of the central organization or the network of the branch office;

[0032] In an actual implementation process, the MAC address information includes: MAC address and VLAN ID (ID). The notification message can specifically be an IS-IS LSP (Link State PDU, Link State Protocol Data Unit) message, and the format of a TLV (Type Length Value,...

Embodiment 2

[0055] by figure 1 The EVI network shown is taken as an example, and the specific operation process of the method in the first embodiment above is described in detail. exist figure 1 In the shown EVI network applied to an enterprise, Site1 is the central office network, Site2 and Site3 are branch office networks, ED1 is the ED in Site1, ED2 is the ED in Site2, and ED3 is the ED in Site3.

[0056] ED1, ED2, and ED3 have been configured for the identity of the network they belong to. Among them, the identity of the network configured on ED1 is the central organization network, and the identity of the network configured on ED2 and ED3 is the branch office network.

[0057] When ED1 advertises MAC address information 1.1.1.1 and VLAN1 to other EDs: ED2 and ED3, it generates an IS-IS LSP message carrying MAC address information 1.1.1.1, VLAN1 and network identity information. Since the network to which ED1 belongs is the central organization Therefore, the network carries a value...

Embodiment 3

[0061] Regarding the method in the first embodiment above, the embodiment of the present application provides an ED in the EVI network to which the method can be applied. Such as Figure 4 As shown, the following modules are included in the ED: a receiving module 10, a determining module 20 and a control module 30, wherein:

[0062] The receiving module 10 is used to receive notification messages sent by other EDs in the EVI network, wherein the notification messages carry network identity information and MAC address information, and the network identity information is used to indicate the ED that sent the notification message belongs to The identity of the network, which can be the network of the central organization or the network of the branch office;

[0063] Wherein, the MAC address information may include: a MAC address and a VLAN identifier (ID). In an actual implementation process, the notification message may specifically be an IS-IS LSP message.

[0064] The deter...

Abstract

The application discloses an MAC address information control method in an EVI network and an edge device. The EVI network comprises a central organization network and a plurality of branch organization networks, and both the central organization network and the branch organization networks comprise the edge device (ED). The method, which is applied to the ED, includes the following steps: a notification message sent by a first ED in the EVI network, which carries network identity information and MAC address information, is received, the network identity information is used for indicating the identity of the network owning the ED sending the notification message, and the identity is the central organization network or the branch organization network; according to the value of the network identity information in the notification message, the identity of the network owning the first ED is determined; and according to the identity of the network owning the device and the determined identity of the network owning the first ED, whether an MAC forwarding table entry containing the MAC address information in the notification message is added into an MAC forwarding table or not is determined.

Description

technical field [0001] The present application relates to the technical field of communication networks, in particular to a method for controlling MAC address information in an EVI network and an edge device. Background technique [0002] In order to achieve high reliability and redundant deployment, and provide better services, most enterprise networks and their data centers usually deploy multiple data centers in different places (that is, different geographical locations) to achieve load sharing and high reliability, and to achieve Free migration of virtual machines between data centers. Since the migration process of the virtual machine is transparent to the user, and the IP (Internet Protocol, Internet Protocol) address cannot be changed, it is necessary to implement Layer 2 network interconnection between data centers distributed in different places. EVI (Ethernet Virtualization Interconnection, Ethernet Virtual Interconnection) is a major Layer 2 network interconnect...
