In the embodiment of the present invention, need member device (PE device A and PE equipment B), PE equipment 2, the CE equipment 2 deploy two-layer protocol at CE equipment 1, IRF stack equipment (PE equipment 1), this two-layer protocol specifically includes but not limited to: STP and/or MVRP (Multiple Virtual Local AreaNetwork Registration Protocol, many virtual local network log-on protocols) etc.Based on the two-layer protocol of affixing one's name in each its upper side, user network 1 and user network 2 can be carried out the intercommunication based on two-layer protocol.
Under above-mentioned application scenarios, as shown in Figure 3, the method for this message transmissions specifically comprises the following steps:
Step 301, the member device (as the PE device A in IRF stack equipment or PE equipment B) in IRF stack equipment determines that this member device needs to carry out the soft reboot upgrading of ISSU.
Step 302, carry out in the process of soft reboot upgrading of ISSU at member device, this member device sends LACP message by the physical port be connected with peer network device to peer network device.
In the embodiment of the present invention, at least specific identifier is carried in this LACP message, and this specific identifier is used to indicate peer network device when sending two-layer protocol message or multicast message to IRF stack equipment, the preferential physical port by not receiving the LACP message carrying specific identifier sends.
As shown in Figure 2, PE device A in IRF stack equipment is in the process of soft reboot upgrading of carrying out ISSU, PE device A (member device) sends LACP message by the physical port B1 be connected with CE equipment 1 to CE equipment 1, specific identifier is carried in this LACP message, and this specific identifier is used to indicate CE equipment 1 when sending two-layer protocol message or multicast message to IRF stack equipment (PE equipment 1), the preferential physical port by not receiving the LACP message carrying specific identifier sends.PE device A (member device) sends LACP message by the physical port B3 be connected with PE equipment 2 to PE equipment 2, specific identifier is carried in this LACP message, and this specific identifier is used to indicate PE equipment 2 when sending two-layer protocol message or multicast message to IRF stack equipment (PE equipment 1), the preferential physical port by not receiving the LACP message carrying specific identifier sends.
Wherein, when soft reboot upgrading IRF stack equipment (PE equipment 1) being carried out to ISSU, need the soft reboot upgrading successively each member device being carried out to ISSU, instead of all member devices are carried out to the soft reboot upgrading of ISSU simultaneously.When a soft reboot upgrading member device being carried out to ISSU, when the physical port be connected with peer network device is the member port of aggregation port, and the physical port be connected with peer network device is positioned on the current interface board needing the soft reboot carrying out ISSU to upgrade, and the physical port be connected with peer network device is when having opened LACP, then: the master control borad of this member device needs to generate the LACP message carrying specific identifier, and by the physical port be connected with peer network device, this LACP message is sent to peer network device.Wherein, specific identifier is specifically as follows a flag bit or a TLV (Type Length Value, type lengths values), and this specific identifier is for distinguishing existing LACP message.
In prior art, the interface board of member device periodically sends LACP message by the physical port be connected with peer network device to peer network device, to maintain the stable state of polymerization.When member device needs the soft reboot upgrading carrying out ISSU, the interface board of member device cannot send LACP message by the physical port be connected with peer network device to peer network device, thus causes peer network device can not forwarding data owing to can not receive LACP message thus allowing link become non-selected state.Based on this, in the embodiment of the present invention, the master control borad of member device adopts agent skill group of giving out a contract for a project, namely, when interface board cannot send LACP message by the physical port be connected with peer network device to peer network device, interface board is replaced to send LACP message by the physical port be connected with peer network device to peer network device by master control borad.Based on this, in the process of soft reboot upgrading of member device being carried out to ISSU, the master control borad of member device needs to generate LACP message, and by the physical port be connected with peer network device, this LACP message is sent to peer network device.In order to distinguish with the LACP message of prior art, the master control borad of this member device needs to generate the LACP message carrying specific identifier, and this specific identifier is used to indicate peer network device when sending two-layer protocol message or multicast message to IRF stack equipment, the preferential physical port by not receiving the LACP message carrying specific identifier sends.
Step 303, peer network device receives the LACP message carrying specific identifier that the member device in IRF stack equipment sends, and when sending two-layer protocol message or multicast message to IRF stack equipment, the preferential physical port by not receiving the LACP message carrying specific identifier sends.
In the embodiment of the present invention, peer network device is not preferentially by receiving the physical port of the LACP message carrying specific identifier, send the process of two-layer protocol message or multicast message to IRF stack equipment, specifically include but not limited to: peer network device judges currently whether there is the two-layer protocol message or multicast message that needs are sent to IRF stack equipment by the physical port that receives the LACP message carrying specific identifier; If existed, then peer network device is from all physical ports be connected with IRF stack equipment, select a physical port not receiving the LACP message carrying specific identifier, and send two-layer protocol message or multicast message by the physical port of current selection to IRF stack equipment.
In the embodiment of the present invention, two-layer protocol message is specifically as follows based on the two-layer protocol message of STP or the two-layer protocol message based on many MVRP.When IRF stack equipment is PE equipment, when peer network device is CE equipment, peer network device preferentially sends two-layer protocol message by the physical port not receiving the LACP message carrying specific identifier to IRF stack equipment.Multicast message is specifically as follows the multicast message based on STP or the multicast message based on MVRP.When IRF stack equipment is PE equipment, when peer network device is PE equipment, peer network device preferentially sends multicast message by the physical port not receiving the LACP message carrying specific identifier to IRF stack equipment.Wherein, multicast message is specially and the target MAC (Media Access Control) address of two-layer protocol message is revised as the message after designated multicast MAC Address.
As shown in Figure 2, when PE device A (member device) sends to CE equipment 1 the LACP message carrying specific identifier by the physical port B1 be connected with CE equipment 1, the LACP message carrying specific identifier that CE equipment 1 will be sent by the member device in physical port A1 reception IRF stack equipment, when sending two-layer protocol message to IRF stack equipment, CE equipment 1 preferentially sends two-layer protocol message by the physical port (as physical port A2) not receiving the LACP message carrying specific identifier to IRF stack equipment.When PE device A (member device) sends to PE equipment 2 the LACP message carrying specific identifier by the physical port B3 be connected with PE equipment 2, the LACP message carrying specific identifier that PE equipment 2 will be sent by the member device in physical port C1 reception IRF stack equipment, when sending multicast message to IRF stack equipment, PE equipment 2 preferentially sends multicast message by the physical port (as physical port C2) not receiving the LACP message carrying specific identifier to IRF stack equipment.
Further, when CE equipment 1 sends two-layer protocol message by the physical port (as physical port A2) not receiving the LACP message carrying specific identifier to IRF stack equipment, PE equipment B (member device) will be received CE equipment 1 and sends two-layer protocol message by physical port B2, the soft reboot upgrading of ISSU is not carried out because PE equipment B is current, therefore PE equipment B can receive two-layer protocol message and to go forward side by side row relax, this two-layer protocol message is encapsulated as multicast message, and by two-layer protocol tunnel, multicast message is sent to PE equipment 2.In like manner, when PE equipment 2 sends multicast message by the physical port (as physical port C2) not receiving the LACP message carrying specific identifier to IRF stack equipment, PE equipment B (member device) will be received PE equipment 2 and sends multicast message by physical port B4, the soft reboot upgrading of ISSU is not carried out because PE equipment B is current, therefore PE equipment B can be gone forward side by side row relax by receiving group message, the target MAC (Media Access Control) address of multicast message is reduced to original target MAC (Media Access Control) address, to obtain corresponding two-layer protocol message, and two-layer protocol message is sent to CE equipment 1.
Based on technique scheme, in the embodiment of the present invention, member device in IRF stack equipment is in the process of soft reboot upgrading of carrying out ISSU, by sending the LACP message carrying specific identifier to peer network device, to make peer network device when sending two-layer protocol message or multicast message to IRF stack equipment, the preferential physical port by not receiving the LACP message carrying specific identifier sends, thus avoid two-layer protocol message or multicast message cannot passing through provider network, and avoid the two-layer protocol disconnecting between user network, ensure that the two-layer protocol tunnel that same user sets up between the user network of different geographical is still unimpeded to the full extent, realize the stable of two layers of related protocol not interrupt with business.
