Description
Technical Field
The invention relates to the technical field of network communication, in particular to a method, a storage medium and equipment for automatically switching service ports of an L2 VPN.
Background
The VPN can be regarded as a private network isolated from a public network, and only resources allowed by the private network access can be mutually connected and intercommunicated, so that the resources are not maliciously interfered and damaged.
The L2VPN belongs to a kind of VPN technology, and the L2VPN has a close relationship with a layer 2 (i.e., a data link layer) in a 7-layer structure. That is, the tunnel encapsulation constituting the VPN is completed at the data link layer, and the client maps its three-layer routing to the network at the data link layer.
For MPLS L2VPN, after a packet is connected to the network, a header of a packet is repackaged in two layers to add MPLS header information, and two layers of switching are performed through a tunnel (transfer channel) created in advance, so that the packet is transferred to a destination one by one. In the process, the data packet does not need to be further analyzed, and complex routing decision does not need to be made on each network node, so that the routing information of an enterprise can be shielded, the security is enhanced, the requirement on an operation network is reduced, and the method is more suitable for VPN access of a large enterprise.
At present, an enterprise establishes its own network by a line provided by a leased operator, and the line is carried by L2VPN, as shown in fig. 1, a SG interface is generally used for conventional service access protection, and at this time, two physical links can no longer be used independently.
Disclosure of Invention
The invention provides a method, a storage medium and equipment for automatically switching service ports of an L2VPN, which can at least solve one of the technical problems in the background technology.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for automatically switching service ports of L2VPN comprises the following steps,
step 1: the L2VPN AC port is configured with a main AC and a standby AC;
step 2: the main AC and the standby AC can be physical ports or sub-interfaces, if VLAN packaged by the main AC and the standby AC of the sub-interfaces needs to be the same;
and step 3: when the DOWN condition occurs in the main AC physical, the AC port service is switched, and the physical state of the standby AC port is judged;
and 4, step 4: if the standby AC port is in physical UP, switching to the standby AC port;
and 5: if the standby AC port is also DOWN, the switching is not carried out;
in yet another aspect, the present invention also discloses a computer readable storage medium storing a computer program, which when executed by a processor causes the processor to perform the steps of the method as described above.
In yet another aspect, the present invention also discloses a computer device comprising a memory and a processor, the memory storing a computer program which, when executed by the processor, causes the processor to perform the steps of the above method.
According to the technical scheme, the AC ports of the L2VPN are set as the main AC port and the standby AC port, and only one AC port of the traditional L2VPN is provided. The backup of service access cannot be made, but the SG port is very inflexible to make the backup, and two ports are completely occupied, and the invention solves the problem.
The invention solves the limitation that SG binding is necessary for protecting the L2VPN service access AC port in the network, so that the main AC port and the standby AC port can be used for accessing the service more independently and flexibly without SG butt joint.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
As shown in fig. 2, the access protection of the present invention uses the primary AC and the standby AC for protection, one service only occupies one VLAN, and other VLANs of the primary AC and the standby AC can continue to independently serve as services without being limited by the SG. The network port resources can be utilized more flexibly and fully.
The method comprises the following specific steps:
as shown in fig. 3, a method for automatically switching service ports by L2VPN according to this embodiment includes:
the L2VPN AC port is configured with a main AC and a standby AC;
the main AC port and the standby AC port can be both physical ports and can also be sub-interfaces of the same VLAN;
when the DOWN condition occurs in the main AC physical, the AC port service is switched, and the physical state of the standby AC port is judged;
if the standby AC port is in physical UP, switching to the standby AC port;
if the standby AC port is also DOWN, the switching is not carried out;
the following are examples of configurations of the present invention:
0/6.1 and 0/5.1 are used as main and standby AC ports, when the ports are both UP in normal 0/6 and 0/5, 0/6.1 is used for service access, and when a link failure occurs in 0/6, the service is switched to 0/5.1

The other subinterfaces of 0/6 and 0/5 may still be configured for other services, which the SG interface cannot.
For example, as follows, 0/6.2 and 0/5.2 may configure two services respectively

While VLAN 2 can only configure one service if SG interfaces are used, for example:
