Description

MAC address learning method and device
Technical Field
The present application relates to the field of network communication technologies, and in particular, to a method and an apparatus for MAC address learning.
Background
An EVPN (Ethernet Virtual Private Network) is a two-layer VPN (Virtual Private Network) technology, where MP-BGP (multi-Protocol-Border Gateway Protocol) is used on a control plane to announce routing information, and VXLAN (Virtual eXtensible local area Network) is used on a data plane to forward user packets.
In the EVPN network, a user port connected to a VM (Virtual Machine) on a VTEP (VXLAN Tunnel End Point) can turn on a dynamic MAC address learning high-quality function. Specifically, if the VTEP receives the user packet of the same source MAC address from both the first user port on which the dynamic MAC address learning high-priority function is activated and the second user port on which the dynamic MAC address learning high-priority function is not activated, the egress interface in the MAC entry including the source MAC address in the MAC forwarding table is preferentially set as the first user port.
For example, after receiving a user packet with a source MAC address of VM-MAC from a user port PortA, the VTEP creates a MAC entry including VM-MAC if a MAC entry including VM-MAC does not exist in the MAC forwarding table, and sets an egress interface in the MAC entry to PortA. Subsequently, the VTEP receives a user packet with a source MAC address of VM-MAC from the user port PortB, at this time, if PortA does not start the dynamic MAC address learning high-priority function, the outgoing interface in the MAC entry is updated from PortA to PortB, and if PortA starts the dynamic MAC address learning high-priority function, the outgoing interface in the MAC entry is not updated to PortB, but the outgoing interface is maintained as PortA.
Disclosure of Invention
In view of the above, the present application provides a MAC address learning method and apparatus.
Specifically, the method is realized through the following technical scheme:
in one aspect, a MAC address learning method is provided, which is applied to VTEP in EVPN, and includes:
receiving a MAC address synchronized by a remote VTEP;
judging whether an output interface corresponding to the MAC address is a user port with a dynamic MAC address learning high-quality function opened or not;
and if so, forbidding updating the output interface corresponding to the MAC address, and sending the MAC address to the remote VTEP so that the remote VTEP learns the MAC address again.
In another aspect, an apparatus for MAC address learning is provided, where the apparatus is applied to VTEP in EVPN, and the apparatus includes:
a receiving unit, configured to receive a MAC address synchronized by a remote VTEP;
the judging unit is used for judging whether the output interface corresponding to the MAC address received by the receiving unit is a user port with a dynamic MAC address learning high-priority function opened or not;
and the processing unit is used for forbidding updating the outgoing interface corresponding to the MAC address and sending the MAC address to the remote VTEP so as to enable the remote VTEP to relearn the MAC address if the judging result of the judging unit shows that the outgoing interface corresponding to the MAC address is the user port with the opened dynamic MAC address learning high-priority function.
According to the technical scheme, after the MAC address synchronized by the remote VTEP is received, whether the output interface corresponding to the MAC address is the user port with the dynamic MAC address learning high-priority function opened or not is judged, if yes, the output interface is not updated but is kept unchanged, and the MAC address is sent to the remote VTEP so that the remote VTEP learns the MAC address again. Therefore, the dynamic MAC address learning high-priority function can not only take effect on the MAC address of the local VM, but also take effect on the MAC address synchronized by the remote VTEP, namely, the global effect of the dynamic MAC address learning high-priority function of the user port is ensured.

In the prior art, the dynamic MAC address learning high-quality function can only take effect for the MAC address of the local VM, but does not take effect for the MAC address synchronized by the remote VTEP. That is, after receiving the MAC address synchronized by the remote VTEP, the VTEP updates the outgoing interface even if the outgoing interface in the corresponding MAC entry is the user port with the dynamic MAC address learning high-quality function. In order to solve the above problem, the following embodiments of the present application provide a MAC address learning method and a MAC address learning apparatus to which the method can be applied.
The MAC address learning method according to the embodiment of the present application may be performed by a VTEP in EVPN, and the method includes: the local VTEP receives the MAC address synchronized by the remote VTEP; the local terminal VTEP judges whether an output interface corresponding to the MAC address is a user port with a dynamic MAC address learning high-priority function opened or not, if so, the output interface is prohibited from being updated, and the MAC address is sent to the remote terminal VTEP so that the remote terminal VTEP learns the MAC address again; if the judgment result is negative, the output interface is updated.
In the method of the foregoing embodiment of the present application, after receiving a MAC address synchronized by a remote VTEP, it is determined whether an outgoing interface corresponding to the MAC address is a user port with a dynamic MAC address learning high-priority function being opened, if so, the outgoing interface is not updated but remains unchanged, and the MAC address is further sent to the remote VTEP, so that the remote VTEP learns the MAC address again. Therefore, the dynamic MAC address learning high-priority function can not only take effect on the MAC address of the local VM, but also take effect on the MAC address synchronized by the remote VTEP, namely, the global effect of the dynamic MAC address learning high-priority function of the user port is ensured.
The method of the above embodiment will be described in detail by taking the EVPN shown in fig. 1 as an example. In EVPN as shown in fig. 1, VXLAN Tunnel0 is established between VTEP1 and VTEP2, where VTEP1 may be understood as a home VTEP device and VTEP2 may be understood as a remote VTEP device. The MAC address learning method based on EVPN networking shown in fig. 1, as shown in fig. 2, includes the following steps:
in step S101, VTEP1 receives the MAC address VM-MAC synchronized by VTEP 2.
Wherein, the interface of the VTEP1 receiving the VM-MAC is VXLAN Tunnel interface Tunnel 0.
In step S102, the VTEP1 determines whether the output interface (denoted as Port1_ a) corresponding to the VM-MAC is the user Port with the dynamic MAC address learning high-quality function turned on, if so, step S103 is executed, otherwise, step S104 is executed.
Specifically, the MAC address learned from the user port with the dynamic MAC address learning high-priority function may be recorded in the MAC address list in advance. For example, for each user port on which the dynamic MAC address learning high-priority function is opened on the present device, the MAC table entry whose interface is the user port is found in the MAC forwarding table, and the MAC address included in the MAC table entry is added to the MAC address list. In this way, in step S102, the received MAC address may be matched with the MAC address list (where, if the MAC address list includes a plurality of MAC addresses, the received MAC address is matched with the plurality of included MAC addresses one by one), and if the received MAC address is matched with the received MAC address, it is determined that the output interface corresponding to the received MAC address is the user port with the dynamic MAC address learning high-quality function being turned on. The list of all MAC addresses learned from the user port with the dynamic MAC address learning high-quality function is collected in advance, and when the MAC address synchronized by the remote VTEP is received, the list is directly matched with the MAC address to judge whether the output interface corresponding to the synchronized MAC address is the user port with the dynamic MAC address learning high-quality function, so that the judgment efficiency can be improved.
Obviously, after receiving the MAC address synchronized by the remote VTEP, the method may further search the outgoing interface corresponding to the MAC address from the MAC forwarding table, and then determine whether the outgoing interface is a user port with a dynamic MAC address learning high-quality function. The embodiment of the present application does not limit this.
Step S103, forbidding updating of the outgoing interface, namely forbidding modifying of the outgoing interface (Port 1_ A) corresponding to the VM-MAC in the MAC forwarding table, maintaining the outgoing interface as Port1_ A, and sending a MAC synchronization message carrying the VM-MAC to the VTEP2 so that the VTEP2 learns the VM-MAC again.
Specifically, after receiving a MAC synchronization message carrying a VM-MAC sent by VTEP1, VTEP2 searches an egress interface corresponding to the VM-MAC in a MAC forwarding table, where the found egress interface is a local user port, determines whether the local user port has a dynamic MAC address learning high-priority function, and if not, VTEP2 obtains a VXLAN Tunnel interface Tunnel0 that receives the MAC synchronization message, and then updates the egress interface corresponding to the VM-MAC in the MAC forwarding table to the obtained VXLAN Tunnel interface Tunnel 0.
Step S104, updating the output interface.
In step S104, VTEP1 updates the outgoing interface corresponding to the VM-MAC in the MAC forwarding table to VXLAN Tunnel interface Tunnel0 that received the VM-MAC.
Subsequently, after Port1_ a turns off the dynamic MAC address learning high-priority function, if VTEP1 receives the synchronized MAC address VM-MAC again, then VTEP1 executes step S104 after the determination operation of step S102 is completed.
In another embodiment, as shown in fig. 3, the MAC address learning method based on EVPN networking shown in fig. 1 includes the following steps:
in step S201, VTEP1 receives the MAC address VM-MAC synchronized by VTEP 2.
Specifically, after receiving a user packet with a source MAC address of VM-MAC from a local user Port2_ B, VTEP2 caches a correspondence between VM-MAC and an egress interface VXLAN Tunnel0 before updating an egress interface corresponding to VM-MAC in a MAC forwarding table, then updates the egress interface corresponding to VM-MAC in the MAC forwarding table to Port2_ B, and synchronizes the VM-MAC to VTEP 1.
Wherein, the interface of the VTEP1 receiving the VM-MAC is VXLAN Tunnel interface Tunnel 0.
In step S202, the VTEP1 determines whether the output interface (denoted as Port1_ a) corresponding to the VM-MAC is the user Port with the dynamic MAC address learning high-quality function turned on, if so, step S203 is executed, otherwise, step S204 is executed.
Specifically, the MAC address learned from the user port with the dynamic MAC address learning high-priority function may be recorded in the MAC address list in advance. For example, for each user port on which the dynamic MAC address learning high-priority function is opened on the present device, the MAC table entry whose interface is the user port is found in the MAC forwarding table, and the MAC address included in the MAC table entry is added to the MAC address list. In this way, in step S102, the received MAC address may be matched with the MAC address list (where, if the MAC address list includes a plurality of MAC addresses, the received MAC address is matched with the plurality of included MAC addresses one by one), and if the received MAC address is matched with the received MAC address, it is determined that the output interface corresponding to the received MAC address is the user port with the dynamic MAC address learning high-quality function being turned on. The list of all MAC addresses learned from the user port with the dynamic MAC address learning high-quality function is collected in advance, and when the MAC address synchronized by the remote VTEP is received, the list is directly matched with the MAC address to judge whether the output interface corresponding to the synchronized MAC address is the user port with the dynamic MAC address learning high-quality function, so that the judgment efficiency can be improved.
Obviously, after receiving the MAC address synchronized by the remote VTEP, the method may further search the outgoing interface corresponding to the MAC address from the MAC forwarding table, and then determine whether the outgoing interface is a user port with a dynamic MAC address learning high-quality function. The embodiment of the present application does not limit this.
In step S203, the update of the outbound interface is prohibited, that is, the outbound interface corresponding to the VM-MAC in the MAC forwarding table (the outbound interface is Port1_ a) is prohibited from being modified, but the outbound interface is maintained as Port1_ a, and a MAC revocation message carrying the VM-MAC is sent to VTEP2, so that VTEP2 learns the VM-MAC again.
Specifically, after receiving a MAC revocation message carrying a VM-MAC sent by VTEP1, VTEP2 searches an egress interface corresponding to the VM-MAC in a MAC forwarding table, where the found egress interface is a local user Port2_ B, and determines whether Port2_ B activates a dynamic MAC address learning high-priority function, and if not, VTEP2 directly updates the egress interface corresponding to the VM-MAC in the MAC forwarding table to a cached VXLAN Tunnel interface Tunnel0 corresponding to the MAC address.
In this embodiment, before the VTEP2 updates the outgoing interface corresponding to the VM-MAC in the MAC address table from the VXLAN Tunnel interface Tunnel0 to the local user Port2_ B, the corresponding relationship between the VM-MAC and the outgoing interface Tunnel0 before updating is cached, so that when the outgoing interface corresponding to the VM-MAC in the MAC address forwarding table is updated after the MAC revocation message carrying the VM-MAC sent by the VTEP1 is received, the outgoing interface is directly restored to the cached VXLAN Tunnel interface Tunnel0, thereby further saving the time required for acquiring the interface receiving the MAC revocation message, and improving the working efficiency.
Step S204, updating the output interface.
In step S204, the VTEP1 updates the outgoing interface corresponding to the VM-MAC in the MAC forwarding table to the VXLAN Tunnel interface Tunnel0 that received the VM-MAC.
Subsequently, after Port1_ a turns off the dynamic MAC address learning high-priority function, if VTEP1 receives the synchronized MAC address VM-MAC again, then VTEP1 performs step S204 after the determination operation of step S202 is completed.
