VxLAN role

This role facilitates the configuration of virtual extensible LAN (VxLAN) attributes. It supports the configuration of virtual networks, Ethernet virtual private network (EVPN) and network virtualization Edge (NVE). This role is abstracted for dellos10 device.

The VxLAN role requires an SSH connection for connectivity to a Dell EMC Networking device. You can use any of the built-in OS connection variables.

Installation

ansible-galaxy install Dell-Networking.dellos_vxlan

Role variables

• Role is abstracted using the ansible_network_os variable that can take dellos10 values
• If variable dellos_cfg_generate is set to true, it generates the role configuration commands in a file
• Any role variable with a corresponding state variable setting to absent negates the configuration of that variable
• Setting an empty value for any variable negates the corresponding configuration
• Variables and values are case-sensitive

dellos_vxlan keys

NOTE: Asterisk (*) denotes the default value if none is specified.

Connection variables

Ansible Dell EMC Networking roles require connection information to establish communication with the nodes in your inventory. This information can exist in the Ansible group_vars or host_vars directories or inventory, or in the playbook itself.

NOTE: Asterisk (*) denotes the default value if none is specified.

Dependencies

The dellos_vxlan role is built on modules included in the core Ansible code. These modules were added in Ansible version 2.2.0.

Example playbook

This example uses the dellos_vxlan role to configure the VxLAN network, source IP address on VxLAN tunnel endpoint and virtual networks. It creates a hosts file with the switch details, a host_vars file with connection variables, and the corresponding role variables.

When dellos_cfg_generate is set to true, the variable generates the configuration commands as a .part file in build_dir path. By default, the variable is set to false. This example writes a simple playbook that only references the dellos_vxlan role. The sample host_vars given below is for dellos10.

Sample hosts file

leaf1 ansible_host= <ip_address>
