community.network.cnos_bgp – Manage BGP resources and attributes on devices running CNOS

Note

This plugin is part of the community.network collection.

To install it use: ansible-galaxy collection install community.network.

To use it in a playbook, specify: community.network.cnos_bgp.

Synopsis

  • This module allows you to work with Border Gateway Protocol (BGP) related configurations. The operators used are overloaded to ensure control over switch BGP configurations. This module is invoked using method with asNumber as one of its arguments. The first level of the BGP configuration allows to set up an AS number, with the following attributes going into various configuration operations under the context of BGP. After passing this level, there are eight BGP arguments that will perform further configurations. They are bgpArg1, bgpArg2, bgpArg3, bgpArg4, bgpArg5, bgpArg6, bgpArg7, and bgpArg8. For more details on how to use these arguments, see [Overloaded Variables]. This module uses SSH to manage network device configuration. The results of the operation will be placed in a directory named ‘results’ that must be created by the user in their local directory to where the playbook is run.

enablePassword
string
Configures the password used to enter Global Configuration command mode on the switch. If the switch does not request this password, the parameter is ignored.While generally the value should come from the inventory file, you can also specify it as a variable. This parameter is optional. If it is not specified, no default value will be used.
host
string / required
This is the variable used to search the hosts file at /etc/ansible/hosts and identify the IP address of the device on which the template is going to be applied. Usually the Ansible keyword {{ inventory_hostname }} is specified in the playbook as an abstraction of the group of network elements that need to be configured.
outputfile
string / required
This specifies the file path where the output of each command execution is saved. Each command that is specified in the merged template file and each response from the device are saved here. Usually the location is the results folder, but you can choose another location based on your write permission.
password
string / required
Configures the password used to authenticate the connection to the remote device. The value of the password parameter is used to authenticate the SSH session. While generally the value should come from the inventory file, you can also specify it as a variable. This parameter is optional. If it is not specified, no default value will be used.
username
string / required
Configures the username used to authenticate the connection to the remote device. The value of the username parameter is used to authenticate the SSH session. While generally the value should come from the inventory file, you can also specify it as a variable. This parameter is optional. If it is not specified, no default value will be used.
