Description
Technical Field
The invention relates to the technical field of network communication, in particular to a VPWS multi-active service connectivity identification method.
Background
Evpn (ethernet Virtual Private network) is a VPN technology for two-layer network interconnection. The EVPN technology transfers the MAC address learning and publishing process between two layers of networks of different network sites from a data plane to a control plane through an extended BGP protocol. An EVPN VPWS (Virtual Private Wire Service) provides a P2P L2VPN Service scheme based on an EVPN Service architecture, where a control layer uses MP-BGP to advertise EVPN routing information and a data layer uses tunnel encapsulation. The data message of the user network is directly forwarded through the AC and the PW under the cross connection without searching an MAC forwarding table entry, and point-to-point two-layer service is provided for the user.
As shown in fig. 1, the EVPN VPWS model includes the following parts.
CE (Customer Edge), Customer network side equipment directly connected to the service provider network.
PE (Provider Edge), service Provider network side device connected to CE. The PE is mainly responsible for the access of the EVPN service, and completes the mapping and forwarding of the message from the user network to the public network tunnel and from the public network tunnel to the user network.
AC (access Circuit), physical Circuit or virtual Circuit connecting CE and PE, such as Ethernet interface, VLAN, PPP connection on physical interface. The AC attributes include the encapsulation type, the maximum transmission unit MTU, and the interface parameters for the particular link type.
PW (Pseudowire), a virtual bidirectional connection between two PEs, consisting of a pair of unidirectional virtual connections in opposite directions. The EVPN VPWS simplifies a control and data model, BGP is used as a uniform control plane, a routing function and a next hop iteration function of the BGP are used for selecting a backbone network flow path, and a PW (pseudo wire) does not need to be manually specified.
A public network Tunnel (Tunnel) which passes through an IP or MPLS backbone network and is used for bearing a Tunnel of the PW, wherein one public network Tunnel can bear a plurality of PWs, and the public network Tunnel can be an MPLS Tunnel, a GRE Tunnel or an SRv6 Tunnel.
Cross connection (Cross connect), a connection formed by two physical circuits or virtual circuits in series, where a message received from one physical circuit or virtual circuit is directly switched to another physical circuit or virtual circuit for forwarding, and the Cross connection includes AC-to-AC Cross connection and AC-to-PW Cross connection.
EVPL instances, which are in one-to-one correspondence with ACs, each EVPL instance has a service ID. The EVPL instance of the home PE corresponds to the EVPL instance of the remote PE one-to-one. The PEs mutually transmit EVPN routes with service IDs to construct forwarding table entries to forward or receive service flows of different ESs, so that point-to-point interconnection is realized.
The EVPN-VPWS instance is deployed on the boundary PE and has a service combination of common access or network side attributes, and a BGP-EVPN address family transfers routes based on RD and RT attributes configured in each instance.
As shown in fig. 2, the impact of a PE single point failure on network services is avoided, and the reliability of the network is improved, and the CE is connected to two PEs to form a redundant backup group, which is called EVPN VPWS dual homing. When a CE is connected to multiple PEs via different Ethernet links, these links form an ES (Ethernet Segment), and identify that they belong to the same ES by using the same esi (ES identifier). The EVPN VPWS dual-homing redundancy backup mode has two networking scenes of dual-homing single-living and dual-homing dual-living.
Under the dual-homing single-active redundancy mode, only one of PE1 and PE2 forwards the flow, and two PWs on PE1 and PE2 are in a main-standby relationship, so that the flow is immediately switched to a backup PW after the main PW fails, and the flow forwarding is continued. The main PW and the standby PW can be determined by DF election. When the PW of PE1 is unavailable, PE3 starts the backup PW, forwards the message of CE 2 to PE2 through the backup PW, and forwards the message to CE 1 through PE 2.
As shown in fig. 3, in the dual-homing multi-active redundancy mode, two PWs on PE3 form an equivalent load-sharing forwarding data packet. Configuring redundancy mode as multi-active on PE1 and PE2, and configuring the same ESI on the access side interface, both PE1 and PE2 will be in the main DF state. After the forwarding association table is successfully established, the traffic message sent from the AC port can be sent to the remote PE by directly using the corresponding public network tunnel according to the forwarding association table of the tunnel and the EVPL instance. After the far-end PE receives the flow message, the far-end PE searches for a forwarding association table item according to a label encapsulated on the flow message, and then forwards the forwarding association table item to a corresponding AC port. In the dual-homing multi-active networking of fig. 3, the redundancy mode between PE1 and PE2 is dual active, and the configuration and BGP protocol message interaction flow in this scenario is as follows.
And configuring an EVPL instance and an EVPN-VPWS instance on each PE device, wherein the EVPL instance needs to be respectively bound with the AC port and the EVPN-VPWS instance, and each EVPL instance needs to be configured with a local service ID and a remote service ID. After configuration is completed, a forwarding association table entry of the AC port and the EVPL instance is generated on the local PE. The redundancy mode is configured as multi-active on PE1 and PE2, and the same ESI is configured on the access side interface. And the PE1 and the PE2 mutually transmit an ES route, and the ES route carries RD, RT, ESI and Source IP. After receiving the ES route, no DF election is triggered between PE1 and PE2, and both devices are in the primary DF state.
PE1 and PE2 send ES AD routes to PE3, carrying RD, RT, next hop, and multi-Active mode information (All-Active). EVI AD routes are mutually sent among the PE devices, and carry information such as RD, RT (Route-Target), next hop, local service ID, EVPL label or SRv6 SID, main and standby roles and the like. PE1 and PE2 receive the EVI AD routes from PE3, match the RT crossings to the corresponding EVPN-VPWS instances, and iterate MPLS or SRv4 tunnels according to next hop information, or iterate SRv6 tunnels according to SRv6 SID. And if the service ID on the received route is the same as the remote service ID configured on the local EVPL instance through checking, generating a forwarding association table item of the MPLS or SRv4/v6 tunnel and the local EVPL instance.
PE3 receives the EVI AD routes from PE1 and PE2, matches the RT crossings to the corresponding EVPN-VPWS instances, and iterates MPLS or SRv4 tunnels according to the next hop information, or iterates SRv6 tunnels according to SRv6 SID. And if the service ID on the received route is the same as the remote service ID configured on the local EVPL instance through checking, generating a load sharing table entry of the MPLS or SRv4/v6 tunnel and the local EVPL instance. PE1 and PE2 respectively receive EVI AD routes from opposite ends, match RT to cross to corresponding EVPN-VPWS instances, and iterate MPLS or SRv4 tunnels according to next hop information or iterate SRv6 tunnels according to SRv6 SIDs. And if the service ID on the received route is the same as the remote service ID configured on the local EVPL instance and the ESI is also the same, generating an associated BYPASS table entry of the MPLS or SRv4/v6 tunnel and the local EVPL instance.
As shown in fig. 4, after the configuration of the EVPN VPWS is completed, the connectivity of the configured service needs to be confirmed. Conventionally, a CCM mechanism defined by g.8013 is used to confirm service connectivity, an MEP entity is configured on an AC port, and service connectivity is confirmed by periodically sending a CCM message to simulate a service message. In an EVPN VPWS dual-homing and multi-live scenario, because a CCM message sent out from an AC port of PE3 is sent out by load sharing of a PW, only PE1 or PE2 can receive the CCM message, and thus MEPs in PE1 and PE2 both have a fixed state as DOWN and cannot reflect a real EVPN VPWS dual-homing and dual-homing forwarding state.

Further, the notification period for notifying the normal receiving and sending state of the CCM message of the home device to the opposite-end home device is set to be 3 times of the CCM message sending period of the network-side device.
Further, if the opposite-end attribution device does not receive the MEP state sent by the attribution device in 3 times of continuous notification period, the MEP state of the attribution device is cleared.
Further, the normal receiving and sending state of the CCM message of the home equipment is notified to the opposite-end home equipment according to a fixed time interval.
Further, the fixed time interval may be 1S, 2S, 3S, 5S, 10S.

Detailed Description
The present invention will be further explained by describing preferred embodiments of the present invention in detail with reference to the accompanying drawings.
First, a VPWS multi-live service connectivity identification method according to an embodiment of the present invention will be described with reference to fig. 5 to 7, which is used for a scheme of confirming connectivity using a CCM mechanism of g.8013 in an EVPN VPWS dual-homed dual-live scenario, and has a wide application scenario.
As shown in fig. 5 to 7, the method for identifying VPWS multi-live service connectivity according to the embodiment of the present invention includes the following steps:
as shown in fig. 5 and 7, in S1, an EVPN VPWS dual-homed dual-live scenario is created.
As shown in fig. 7, in S2, according to the routing rule of dual activity, the CCM packet at the AC port of the network-side device PE3 in the scene is sent to the home device PE1 in the scene, and the home device PE1 can normally receive and send the CCM packet. In this embodiment, the CCM message of the AC port of the network side device PE3 is processed by the load sharing algorithm of the PW ECMP, and then is sent to the home device PE 1. Therefore, CCM message transmission and receiving between the home device PE1 and the network side device PE3 are normal, MEPs can normally discover each other, and normal service can be verified.
As shown in fig. 7, in S3, the opposite-end home device PE2 in the scenario cannot normally receive and send a CCM message, and reports a CCM fault.
As shown in fig. 7, in S4, for the problem of the CCM fault reported by the opposite-end home device PE2, the state of the normal transmission and reception of the CCM message of the home device PE1 is notified to the opposite-end home device PE2 through a predefined communication message format, so that the opposite-end home device PE2 displays the state of the CCM fault occurring when the CCM message is not received, and displays the MEP state of the home device PE 1. In this embodiment, an MEP status notification scheme is as follows: the CCM message is sent to the opposite-end home device PE2 from the normal home device PE 1. Referring to the ITU-T g.8013 protocol, when the opposite-end home device PE2 cannot normally receive three continuous CCM messages sent by the AC port of the network-side device PE3, a CCM fault is reported. The notification period of notifying the normal receiving and sending of the CCM messages of the home device PE1 to the opposite-end home device PE2 is set to be 3 times the CCM message sending period of the network-side device PE3, so that the MEP state can be timely sent to the opposite-end home device PE 2. Another MEP status notification scheme is as follows: the normal receiving and sending state of the CCM message of the home device PE1 is notified to the opposite-end home device PE2 according to a fixed time interval, which may be 1S, 2S, 3S, 5S, 10S, and the like. The scheme of the fixed time interval can reduce the number of the state synchronization messages and the occupation of the message MEP state synchronization mechanism on the resources of the attributive equipment.
Further, if the opposite-end home device PE2 does not receive the MEP status sent by the home device PE1 for 3 consecutive times of the notification period, the MEP status of the home device PE1 is cleared.
According to the ITU-T G.8013 protocol, the MEP is the main body for receiving and sending CCM messages, and the index of the MEP is (Level, MegId, MepID). The message format of the special design MEP status synchronization is shown in fig. 6, and fig. 6 is applicable to the above-mentioned dual-homed inter-device fast notification MEP status scheme and the timing notification MEP status scheme. The DMAC and the SMAC can adopt preset MAC addresses for identifying messages of MEP state synchronization. And the double-home and double-active home equipment issues an ACL rule to match the message and sends the message to AC MEP for processing. And after receiving the MEP state message sent by the opposite-end home equipment, the AC MEP analyzes and processes the MEP STATUS for local MEP state presentation.
In the scheme, the service connectivity identification of the EVPN VPWS dual-homed scene can be accurately realized by adopting a scheme that the home device with the normal AC MEP state displays the local CCM transceiving state and the home device with the abnormal AC MEP state displays the AC MEP state of the home device of the opposite terminal according to the identification method of the VPWS multi-homed service connectivity of the embodiment of the invention described above with reference to fig. 5 to 7. The scheme is simple and reliable, and has important significance in practical application.
