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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, when a link fails, the routing table entries of the failed link are updated one by one, and the convergence performance of three-layer flow is limited by the updating speed and the updating number of the routing table entries, so that rapid convergence cannot be realized. In the method for switching the routing table entry outlets provided in the embodiments of the present invention, when a link fails, a member port of a source outlet of a routing table entry of the failed link is replaced with a member port of a destination outlet, and outlets of all routing table entries are updated to a backup link or an reachable link outlet at one time, so that three-layer traffic fast switching is achieved.
Fig. 1 is a schematic flow chart of a method for switching an exit of a routing table entry according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step S11, if judging that the link is failed, obtaining source export information and destination export information of the routing table entry of the failed link;
specifically, a routing table entry in the network device, such as an ARP table entry or an ND table entry, is configured to store a routing prefix + a next hop in hardware, where the next hop includes egress information, that is, a source egress of the routing table entry, and the egress information may be an AP port (aggregation port) or a physical egress. When a certain egress link fails, the egress information of the routing table entry of the failed link needs to be replaced with an available port, i.e., a destination egress, of the standby link, so that, after the link failure is known, the routing table entry egress switching device installed on the network device obtains the source egress information and the destination egress information of the routing table entry of the failed link, i.e., obtains the next hop and the standby port.
Step S12, if judging that the source outlet and the destination outlet of the routing table item are aggregation ports, acquiring a member port of the destination outlet;
and step S13, replacing the member port of the source outlet with the member port of the destination outlet.
Specifically, the routing table entry outlet may be an AP port or a physical port, and the routing table entry outlet switching device first needs to determine whether a source outlet and a destination outlet of the routing table entry are aggregation ports, where a determination method of an aggregation port may determine according to a port type and the like, which is not described herein again, and if the source outlet and the destination outlet are aggregation ports, a member port of the destination outlet is obtained, for example, the routing table entry outlet is AP1, the destination outlet is AP2, both of which are aggregation ports, the member ports of AP1 are D1 and D2, and the member ports of AP2 are D3, D4, and D5. When the source outlet is AP1, to realize fast switching of three-layer traffic from AP1 to AP2, it is only necessary to replace the member port of AP1 with the member port of AP2, that is, the member ports of AP1 are replaced with D3, D4, and D5, so that fast switching of traffic can be realized without depending on updating routing table entries one by one.
After the AP1 link fails, the routing table entry outlet switching device notifies the message of switching the AP1 to the AP2, and directly replaces the member port of the AP1 with the member port of the AP2, at this time, the three-layer traffic is already switched to the AP2, the switching speed is increased from the second level to the millisecond level, and the rapid convergence is realized.
The routing table entry outlet switching device is suitable for scenarios such as STP (Spanning Tree Protocol), MSTP (Multiple Spanning Tree Protocol), MLAG (Multi-Chassis Link Aggregation Group), and the like.
In the method for switching route table entry outlets provided in the embodiments of the present invention, after determining that the source outlet and the destination outlet of the route table entry of the failed link are aggregation ports, the member port of the source outlet is replaced with the member port of the destination outlet, and the outlets of all the route table entries are updated to the backup link or the reachable link outlet at one time, so as to implement fast flow switching.
On the basis of the above embodiment, further, before the obtaining the member port of the destination exit, the method further includes:
if the source outlet of the routing table entry is judged and known to be a physical port, a first aggregation port is created, and the physical port of the source outlet is taken as a member port and added into the first aggregation port;
switching the outlet of the routing table entry from the source outlet to the first aggregation port;
accordingly, the replacing the member port of the source outlet with the member port of the destination outlet includes:
replacing the member port of the first aggregate port with the member port of the destination outlet.
Specifically, a fast switching function is enabled on a port which needs to implement fast switching, and then route table entry learning is performed, the key to implement the fast switching function is that a source exit of a route table entry must be an AP port, if the source exit is not an AP port, a virtual AP port without a member port is created and is denoted as AP1, and a physical port of the source exit is added to the created virtual AP1, so that the virtual AP port becomes a member port of AP 1. If the source egress is an AP port, no creation is required. The source egress of the routing table entry is then switched to the created AP 1. When the link failure needs to switch the routing table entry outlet, the member port of the destination outlet is directly replaced into the created AP1, and if the destination outlet is a physical port, the physical port is directly replaced into the member port of the created AP1, which can also realize three-layer traffic fast switching.
On the basis of the foregoing embodiments, further, before the acquiring the member port of the destination exit, the method further includes:
if the target outlet of the routing table entry is judged and known to be a physical port, a second aggregation port is created, and the physical port of the target outlet is taken as a member port and added into the second aggregation port;
accordingly, the replacing the member port of the source outlet with the member port of the destination outlet includes:
replacing the member port of the source outlet with the member port of the second polymerization port.
Specifically, in practical applications, the destination exit may also be set as an aggregation exit, and if the destination exit is not an AP, a virtual AP without member ports is created, which is denoted as AP2, and a physical port of the destination exit is added to the created virtual AP2, so that the virtual AP becomes a member port of AP 2. If the destination egress is an AP port, no creation is required. When the link failure needs to switch the routing table entry outlet, the member port of the destination outlet is directly replaced into the member port of the source outlet, so that the three-layer flow fast switching can be realized.
On the basis of the above embodiments, the method further includes:
creating a third aggregation port, and adding the member port of the target outlet into the third aggregation port;
switching the outlet of the routing table entry from the source outlet to the third aggregation port;
restoring a member port of the source outlet;
and if the link is judged to be recovered to be normal, replacing the member port of the third aggregation port with the member port of the source outlet, and switching the outlet of the routing table entry from the third aggregation port to the source outlet.
After switching the exit of the routing table entry from the third aggregation port to the source exit, the method further includes:
and deleting the third polymerization port.
Specifically, the foregoing embodiments have implemented the function of fast switching traffic when a link fails, but when link recovery cannot be implemented, the routing table entry outlet originally directed to the AP1 is quickly updated back to the AP 1. Therefore, the following steps are also required to be continued: an AP port without a member port is first created for use as an intermediate process outlet, denoted AP3, and the member port of AP2 is added to AP 3. While switching the routing table entry egress from AP1 to AP 3. And after all the routing table entry outlets are updated to be the AP3, restoring the member port of the AP1 to the original member port. After the link of the AP1 is restored, the member port of the AP3 is replaced with the member port of the AP1, and since the routing table entry outlets all point to the AP3 at this time, after the member ports are all replaced with the member port of the AP1, the traffic is actually switched to the member port of the AP1, thereby realizing fast convergence of the traffic. Meanwhile, after the switch is complete, the routing table entry egress is switched from AP3 to AP 1. After all the routing table entries are updated to the AP1, the AP3 is deleted.
For example, taking the table entry exit switching of ARP/ND as an example, fig. 2 is a schematic flow chart of the ARP/ND table entry exit switching method provided in the embodiment of the present invention, and as shown in fig. 2, a routing table entry exit switching device is divided into three modules according to the purpose, which are: backup port selection module, AP module and routing module, wherein: the backup port selection module is used for selecting a backup outlet when a link fails, notifying the AP module to switch from the main link outlet AP1 to the backup link outlet AP2, and notifying the AP module to switch back from the backup link outlet AP2 to the AP1 when the link is restored; the AP module is used for receiving the information of the backup port selection module, directly replacing the AP1 member port with the AP2 member port when the link fails, creating an AP3 port without the member port to be used as an outlet of the intermediate process, and adding the AP2 member port into the AP 3. And simultaneously, the routing module is informed to update the ARP/ND table entry outlet from the AP1 to the AP 3. Restoring the member port of the AP1 to the original member port; at link restoration, the AP3 member port is replaced with the AP1 member port, and the routing module is simultaneously notified to update the entry exit of the ARP/ND from AP3 to AP 1. When all the ARP/ND are updated to AP1, AP3 is deleted. The routing module is used for receiving the message of the AP module and comprises: the receiving AP module updates the AP1 to AP3 message and the ARP/ND entry egress from AP1 to AP 3. Receiving the message that the AP module AP3 updates to AP1, the ARP/ND table entry egress is updated from AP3 to AP 1.
