Fig. 3 is a schematic flow chart of a route establishment method provided in the present application, where the method is applied to a first routing device, as shown in fig. 3, and the method includes the following steps:

s301, the first routing device acquires configuration information of a virtual private network (virtual private network, VPN) route of the second routing device.

The configuration information comprises target routing information, a target destination address and a target group attribute; the target routing information is the routing information between the source device and the destination device, the first routing device is the virtual routing device of the source device, the second routing device is the virtual routing device of the destination device, and a plurality of SRv tunnels exist between the first routing device and the second routing device.

As an example, the configuration parameters of the first routing device may be as follows:

Loopback0:2::2

Locator:A2::/64

End SID:A2::1

DT6 SID:A2::100

SRv6 Policy:

color:100

endpoint:A1::100

segment-list:<XXX,YYY,A1::1>

the configuration parameters of the second routing device may be as follows:

Loopback0:1::1

Locator:A1::/64

End SID:A1::1

DT6 SID:A1::100

the specific description of each parameter in the above examples may refer to the existing scheme, and will not be described herein.

The target destination address may also be referred to as Prefix and the target Community attribute may also be referred to as Community.

As a possible implementation manner, the first routing device receives the broadcast message of the second routing device, then verifies the target routing identifier to obtain a verification result, and obtains configuration information in the broadcast message when the verification result indicates that the target routing identifier passes verification.

Wherein the broadcast message includes a destination route identification and configuration information for the VPN route.

It should be noted that, for a specific description of this possible implementation manner, reference may be made to the related description in the subsequent part of the specific embodiment of the present application, which is not described herein.

As yet another possible implementation manner, the control plane of the first routing device receives an announcement message of the control plane of the first routing device, where the announcement message includes configuration information of a VPN route of the second routing device, and the first routing device obtains the configuration information of the VPN route of the second routing device from the announcement message, and stores the configuration information in the forwarding plane of the first routing device.

S302, the first routing device determines a target SRv tunnel in the plurality of SRv tunnels according to the target destination address and the target community attribute.

The destination address of the target SRv tunnel is a target destination address, and the community attribute of the target SRv tunnel is a target community attribute.

As one possible implementation manner, the first routing device searches for a SRv tunnel with a destination address as a target destination address and a community attribute as a target community attribute in a plurality of SRv tunnels of a forwarding plane of the first routing device, and determines the SRv6 tunnel as a target SRv tunnel.

S303, the first routing device converts the target routing information into first Internet protocol version 6 (internet protocol version, IPv 6) routing information.

S304, the first routing device sends a first routing message to the source device.

Wherein the first routing message includes first IPv6 routing information.

As a possible implementation manner, the first routing device encapsulates the first IPv6 routing information to obtain a first routing message, and then sends the first routing message to the source device through a data transmission channel between the first routing device and the source device.

It can be appreciated that after the source device receives the first routing message, the source device can learn the first IPv6 routing information in the first routing message, and when the subsequent source device needs to send data, the source device can send data based on the first IPv6 routing information.

Based on the scheme, the first routing device receives configuration information of VPN routing including target routing information, target destination address and target community attribute of the second routing device, then determines a target SRv tunnel in the plurality of SRv tunnels according to the target destination address and the target community attribute, finally converts the target routing information into first IPv6 routing information, and sends the first routing message including the first IPv6 routing information to the source device. Because the target address of the target SRv tunnel is the target destination address in the configuration information of the VPN route, the community attribute is the target community attribute in the configuration information of the VPN route, and the VPN route information is the route information between the source device and the destination device, so that the SRv tunnel corresponding to the VPN route can be determined under the condition that a SRv tunnel exists between the first route device and the second route device, after the first route message including the first IPv6 route information is sent to the source device, the route between the source device and the destination device can be established, and therefore, under the condition that the communication protocol is SRv6, the route can be established through the virtual route device.

The route establishment method provided by the present application is generally described above, and the route establishment method provided by the present application will be further described below with reference to the accompanying drawings.

As a possible implementation manner, the first routing device determines whether the target route identifier is in the virtual route forwarding (virtual routing forwarding, VRF) routing table, if so, determines that the verification result is verification passing, and if not, determines that the verification result is verification failing.

Wherein the VRF routing table includes a plurality of route identifications.

S403, the first routing device acquires configuration information in the broadcast message under the condition that the verification result indicates that the target routing identification passes verification.

As a possible implementation manner, taking the implementation manner in S402 as an example, the first routing device determines whether the verification result is verification passing, if so, determines that the verification result indicates that the target route identifier passes verification, and the first routing device obtains configuration information from the broadcast message. If not, determining that the verification result does not indicate that the target route identification passes the verification, and sending a response failure message to the second routing equipment.

Based on the scheme, the first routing device obtains the configuration information in the broadcast message by receiving the broadcast message of the second routing device, which comprises the target routing identifier and the configuration information of the VPN route, and then verifying the target routing identifier to obtain a verification result, and the scheme of obtaining the configuration information of the VPN route of the second routing device can be realized under the condition that the verification result indicates that the target routing identifier passes verification.
