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. For more information about this module from Lenovo and customizing it usage for your use cases, please visit http://systemx.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.switchmgt.ansible.doc%2Fcnos_bgp.html

Parameters ¶

Parameter	Choices/Defaults	Comments
asNum required	Default: None	AS number
bgpArg1 required	Choices: address-family bestpath bgp cluster-id confederation enforce-first-as fast-external-failover graceful-restart graceful-restart-helper log-neighbor-changes maxas-limit neighbor router-id shutdown synchronization timers vrf Default: None	This is an overloaded bgp first argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg2	Choices: ipv4 or ipv6 always-compare-med compare-confed-aspath compare-routerid dont-compare-originator-id tie-break-on-age as-path med identifier peers Default: None	This is an overloaded bgp second argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg3	Choices: aggregate-address client-to-client dampening distance maximum-paths network nexthop redistribute save synchronization ignore or multipath-relax confed or missing-as-worst or non-deterministic or remove-recv-med or remove-send-med Default: None	This is an overloaded bgp third argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg4	Choices: Aggregate prefix Reachability Half-life time route-map Distance for routes external ebgp or ibgp IP prefix <network> IP prefix <network>/<length> synchronization Delay value direct ospf static memory Default: None	This is an overloaded bgp fourth argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg5	Choices: as-set summary-only Value to start reusing a route Distance for routes internal Supported multipath numbers backdoor map route-map Default: None	This is an overloaded bgp fifth argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg6	Choices: summary-only as-set route-map name Value to start suppressing a route Distance for local routes Network mask Pointer to route-map entries Default: None	This is an overloaded bgp sixth argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg7	Choices: Maximum duration to suppress a stable route(minutes) backdoor route-map Name of the route map Default: None	This is an overloaded bgp seventh argument. Usage of this argument can be found is the User Guide referenced above.
bgpArg8	Choices: Un-reachability Half-life time for the penalty(minutes) backdoor Default: None	This is an overloaded bgp eigth argument. Usage of this argument can be found is the User Guide referenced above.
deviceType required (added in 2.3)	Choices: g8272_cnos g8296_cnos g8332_cnos NE1072T NE1032 NE1032T NE10032 NE2572	This specifies the type of device where the method is executed. The choices NE1072T,NE1032,NE1032T,NE10032, NE2572 are added since version 2.4
enablePassword (added in 2.3)		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 required (added in 2.3)		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 required (added in 2.3)		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 required (added in 2.3)		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 required (added in 2.3)		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.
