This role facilitates the configuration of border gateway protocol (BGP) attributes. It supports the configuration of router ID, networks, neighbors, and maximum path. This role is abstracted for dellos9, dellos6, and dellos10 devices.
The BGP role requires an SSH connection for connectivity to a Dell EMC Networking device. You can use any of the built-in OS connection variables.
ansible-galaxy install Dell-Networking.dellos-bgp
- Role is abstracted using the ansible_network_os variable that can take dellos9, dellos6, and 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

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.
| Key | Required | Choices | Description |
|---|---|---|---|
ansible_host |
yes | Specifies the hostname or address for connecting to the remote device over the specified transport | |
ansible_port |
no | Specifies the port used to build the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_PORT option is used; it defaults to 22 | |
ansible_ssh_user |
no | Specifies the username that authenticates the CLI login for the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_USER environment variable value is used | |
ansible_ssh_pass |
no | Specifies the password that authenticates the connection to the remote device | |
ansible_become |
no | yes, no* | Instructs the module to enter privileged mode on the remote device before sending any commands; if value is unspecified, the ANSIBLE_BECOME environment variable value is used, and the device attempts to execute all commands in non-privileged mode |
ansible_become_method |
no | enable, sudo* | Instructs the module to allow the become method to be specified for handling privilege escalation; if value is unspecified, the ANSIBLE_BECOME_METHOD environment variable value is used |
ansible_become_pass |
no | Specifies the password to use if required to enter privileged mode on the remote device; if ansible_become is set to no this key is not applicable |
|
ansible_network_os |
yes | dellos6/dellos9/dellos10, null* | Loads the correct terminal and cliconf plugins to communicate with the remote device |
NOTE: Asterisk (*) denotes the default value if none is specified.
The dellos-bgp role is built on modules included in the core Ansible code. These modules were added in Ansible version 2.2.0.
This example uses the dellos.dellos-bgp role to configure the BGP network and neighbors. 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-bgp role. The sample host_vars given below is for dellos9.
