This35 module is invoked using method with asNumber as one of its arguments. The first level of36 the BGP configuration allows to set up an AS number, with the following attributes going37 into various configuration operations under the context of BGP. After passing this level,38 there are eight BGP arguments that will perform further configurations. They are bgpArg1,39 bgpArg2, bgpArg3, bgpArg4, bgpArg5, bgpArg6, bgpArg7, and bgpArg8. For more details on40 how to use these arguments, see [Overloaded Variables].41 This module uses SSH to manage network device configuration.42 The results of the operation will be placed in a directory named 'results'43 that must be created by the user in their local directory to where the playbook is run.44 For more information about this module from Lenovo and customizing it usage for your45 use cases, please visit U(http://systemx.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.switchmgt.ansible.doc%2Fcnos_bgp.html)46version_added: "2.3"47extends_documentation_fragment: cnos48options:49 asNum:50 description:51 - AS number52 required: Yes53 default: Null54 bgpArg1:55 description:56 - This is an overloaded bgp first argument.
