Embodiment
For the objects, technical solutions and advantages of the present invention are more clearly understood, develop simultaneously embodiment referring to the drawings, right
Scheme of the present invention is described in further detail.
In the embodiment of the present invention, in order to realize the dynamic vlan attribute logging across data center, for needing to support across number
According to the station network of the dynamic vlan attribute logging function at center, dynamic can be configured on the edge device of the station network in advance
VLAN attribute logging functions.When the ED of the station network receives the VLAN attribute logging messages in the station network,
The VLAN attribute loggings information that VLAN attribute loggings message is carried is from the remote station for being configured with dynamic vlan attribute logging function
Outgoing interface corresponding to the ED of spot net is sent, and eventually arrives at the ED of the remote station network, by the remote station network
ED carries out VLAN attribute loggings in receiving interface, and regenerates VLAN attribute logging reports according to the VLAN attribute logging information
Text, and propagated in the remote station network, so as to realize the dynamic vlan attribute logging across data center.
Below by the station network with EVI, during using GVRP mechanism to carry out VLAN attribute loggings in website, how to lead to
ED is crossed to realize across data center（I.e. cross-site network）Process, technical scheme of the embodiment of the present invention is described in detail.
Referring to Fig. 3, Fig. 3 is dynamic virtual Local Area Network attributes register method flow chart of the embodiment of the present invention, this method application
The edge device ED of station network, is mainly included the following steps that in EVI networks：
Step 301, dynamic vlan attribute logging function is configured on this ED in advance.
By taking Fig. 2 as an example, for station network site1, dynamic vlan attribute logging function is configured in ED1；For website
Network site2, dynamic vlan attribute logging function is configured in ED2.
Wherein, dynamic vlan attribute logging function is configured on ED, shows that the ED supports to carry out VLAN between station network
Attribute logging.
Step 302, the VLAN attribute logging messages received in station network where this ED, by the VLAN attribute loggings
The VLAN attribute loggings information that message carries is corresponding from the ED of the remote station with being configured with dynamic vlan attribute logging function
Outgoing interface is sent.
Outgoing interface corresponding to the ED of remote station is what is established on EVI interfaces, namely this ED between the ED of remote station
Interface on EVI link.
Here VLAN attribute logging messages, just refer to that using the GVRP messages of GVRP mechanism, GVRP VLAN can be realized
Dynamic configuration, be a kind of application based on GARP working mechanisms.
Wherein, exchanged for the information between GARP application entities, it may include there are three class messages（Also referred to as message）, respectively
For statement（Join）Message, cancellation（Leave）Message and cancellation all properties（LeaveAll）Message.Wherein,
Join message, it is divided into the unregistered attribute of statement（JoinEmpty）With the unregistered attribute of statement（JoinIn）Two kinds, area
It is not：JoinEmpty represents attribute of one, the statement without registration itself, and JoinIn represents that one, statement itself is chartered
Attribute.When a GARP application entity wishes that miscellaneous equipment registers the attribute information of oneself, it will externally send Join message；
Some attributes are, it is necessary to which other GARP application entities are noted when the Join message or this equipment static configuration for receiving other entities
During volume, it can also be sent out Join message.
Leave message is divided into canceling unregistered attribute（LeaveEmpty）With the registered attribute of cancellation（LeaveIn）Two kinds,
It is distinguished as：LeaveEmpty represents that nullify one itself nullifies one and itself noted without the attribute registered, LeaveIn expressions
The attribute of volume.When a GARP application entity wishes that miscellaneous equipment nullifies the attribute information of oneself, it will externally send Leave
Message；After the Leave message for receiving other entities nullifies some attributes or static state has nullified some attributes, it also can be to outgoing
Send Leave message.
Nullify all properties（LeaveAll）Message, for nullifying all attributes, so that other GARP application entities weights
New registration originally physically all attribute information, the rubbish attribute in network is periodically removed with this（Such as some attribute
It is deleted, but because equipment powers off suddenly, Leave message is not sent to notify other entities to nullify this attribute）.Often
After individual GARP application entities start, LeaveAll timers will be started simultaneously, GARP application entities will after the timer expiry
Externally send LeaveAll message.
In embodiments of the present invention, in the case that VLAN attribute loggings message is GVRP messages, described VLAN attributes note
Volume information specifically may include attribute event and attribute value, and wherein attribute event can be to nullify all properties（LeaveAll）Thing
Part, the registered attribute of statement（JoinIn）Event, the unregistered attribute of statement（JoinEmpty）Event, nullify registered attribute
（LeaveIn）Event or canceling unregistered attribute（LeaveEmpty）Event, attribute value identify for VLAN（ID）.Certainly, it is right
When using other attribute logging messages, can also there is same or similar attribute logging information.
Step 303, the VLAN attribute logging information that the ED of remote station is sent is received, perform the VLAN attributes of receiving interface
Registration, generates VLAN attribute logging messages corresponding to the VLAN attribute logging information, and by the VLAN attribute logging messages of generation
Sent from all of the port for enabling VLAN attribute logging functions.
The ED for being configured with the remote station network of dynamic vlan registering functional is received in remote station network
During VLAN attribute logging messages, similarly can by the VLAN attribute loggings message carry VLAN attribute loggings information from configuration
Outgoing interface corresponding to the ED of other station networks of dynamic vlan registering functional is sent.
After the ED of the site-local or ED of remote station receives the VLAN attribute logging information that other websites are sent, pass through
VLAN attribute loggings message corresponding to generation, and sent by other ports, it can thus cause in each station network
Equipment, as SW-1, SW-2, SW-3, SW-4 in Fig. 2 can thereon port register VLAN attributes, to ensure this
Message in VLAN can be in station network, and is transmitted between station network.
In this step, this ED receive remote station ED send VLAN attribute logging information after, it is necessary to perform reception
Interface（Receive the interface of the VLAN attribute logging information）VLAN attribute loggings, so, the receiving interface just can be to the VLAN
Message handled.Wherein, the difference of attribute event in the VLAN attribute logging information received, noted according to the VLAN attributes
The method for the VLAN attribute loggings that volume information performs receiving interface also differs, and is specially：
If attribute event is LeaveAll events in the VLAN attribute logging information, institute is nullified on the receiving interface
There are VLAN attributes；
If attribute event is JoinIn events or JoinEmpty events in the VLAN attribute logging information, connect at this
Receive and register all VLAN that attribute value includes in the VLAN attribute logging information on interface；
If attribute event is LeaveIn events or LeaveEmpty events in the VLAN attribute logging information, at this
All VLAN that attribute value includes in the VLAN attribute logging information are nullified on receiving interface.
, can also be according to this after this ED receives the VLAN attribute logging information of ED transmissions of remote station in this step
The local EVI extension VLAN of VLAN attribute loggings information modification, so, this ED cans be based on extension VLAN, and study is arrived pair
The MAC Address answered, so that the message in VLAN effectively is accurately forwarded into corresponding device port.I.e. local EVI extends VLAN
For the MAC Address of limits synchronization to remote station, only learn in each VLAN included by the local EVI extensions VLAN in ED
To MAC Address just allow to be synchronized to remote station.
Wherein, the difference of attribute event in the VLAN attribute logging information received, according to the VLAN attribute logging information
The local EVI extensions VLAN of modification method also differs, and is specially：
If attribute event is LeaveAll events in the VLAN attribute logging information, local EVI extensions are removed
All dynamic vlans in VLAN；
If attribute event is JoinIn events or JoinEmpty events in the VLAN attribute logging information, should
All VLAN that attribute value includes in VLAN attribute logging information are added in local EVI extensions VLAN；
If attribute event is LeaveIn events or LeaveEmpty events in the VLAN attribute logging information, should
All VLAN that attribute value includes in VLAN attribute logging information remove from the EVI extensions VLAN of local.
It should be noted that attribute event is JoinIn events or JoinEmpty things in the VLAN attribute logging information
In the case of part, all VLAN that attribute value includes in the VLAN attribute logging information are to be added to local as dynamic vlan
EVI extension VLAN in.For the VLAN being pre-configured with ED, the present embodiment need not do special processing.
In the present embodiment, VLAN attribute logging messages refer to employ general VLAN attributes registration protocols（GVRP）Report
Text, the method for VLAN attribute logging messages corresponding to ED generation VLAN attribute logging information is concretely：A GVRP messages are generated,
Attribute event in the VLAN attribute logging information is inserted in the attribute event field of the GVRP messages, the VLAN attributes are noted
Attribute value in volume information is inserted in the attribute value field of the GVRP messages.So, ED can be by the transmission of remote station
VLAN attribute logging information, with GVRP message modes, VLAN attribute loggings are carried out according to normal GVRP mechanism in this website.
In the embodiment of the present invention shown in Fig. 3, in order to which after the GVRP messages in website are received, GVRP messages can be taken
The VLAN attribute loggings information announcement of band is configured with dynamic to the remote station for being configured with dynamic vlan registering functional, it is necessary to know
