## Synopsis

- Manages Ethernet Virtual Private Network (EVPN) VXLAN Network Identifier (VNI) configurations on HUAWEI CloudEngine switches.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
bridge_domain_id - / required |  | Specify an existed bridge domain (BD).The value is an integer ranging from 1 to 16777215.
evpn - | Choices: enable ← disable | Create or delete an EVPN instance for a VXLAN in BD view.
route_distinguisher - |  | Configures a route distinguisher (RD) for a BD EVPN instance. The format of an RD can be as follows 1) 2-byte AS number:4-byte user-defined number, for example, 1:3. An AS number is an integer ranging from 0 to 65535, and a user-defined number is an integer ranging from 0 to 4294967295. The AS and user-defined numbers cannot be both 0s. This means that an RD cannot be 0:0. 2) Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. An AS number is an integer ranging from 65536 to 4294967295, and a user-defined number is an integer ranging from 0 to 65535. 3) 4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. A 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers ranging from 0 to 65535. 4) A user-defined number is an integer ranging from 0 to 65535. The AS and user-defined numbers cannot be both 0s. This means that an RD cannot be 0.0:0. 5) 32-bit IP address:2-byte user-defined number. For example, 192.168.122.15:1. An IP address ranges from 0.0.0.0 to 255.255.255.255, and a user-defined number is an integer ranging from 0 to 65535. 6) 'auto' specifies the RD that is automatically generated.
state - | Choices: present ← absent | Manage the state of the resource.
vpn_target_both - |  | Add VPN targets to both the import and export VPN target lists of a BD EVPN instance. The format is the same as route_distinguisher.
vpn_target_export - |  | Add VPN targets to the export VPN target list of a BD EVPN instance. The format is the same as route_distinguisher.
vpn_target_import - / required |  | Add VPN targets to the import VPN target list of a BD EVPN instance. The format is the same as route_distinguisher.

## Notes

Note

- Ensure that EVPN has been configured to serve as the VXLAN control plane when state is present.
- Ensure that a bridge domain (BD) has existed when state is present.
- Ensure that a VNI has been created and associated with a broadcast domain (BD) when state is present.
- If you configure evpn:false to delete an EVPN instance, all configurations in the EVPN instance are deleted.
- After an EVPN instance has been created in the BD view, you can configure an RD using route_distinguisher parameter in BD-EVPN instance view.
- Before configuring VPN targets for a BD EVPN instance, ensure that an RD has been configured for the BD EVPN instance
- If you unconfigure route_distinguisher, all VPN target attributes for the BD EVPN instance will be removed at the same time.
- When using state:absent, evpn is not supported and it will be ignored.
- When using state:absent to delete VPN target attributes, ensure the configuration of VPN target attributes has existed and otherwise it will report an error.
- This module requires the netconf system service be enabled on the remote device being managed.
- Recommended connection is `netconf`.
- This module also works with `local` connections for legacy playbooks.
