## Synopsis

- Manages BGP configurations on NX-OS switches.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
asn - / required |  | BGP autonomous system number. Valid values are String, Integer in ASPLAIN or ASDOT notation.
bestpath_always_compare_med boolean | Choices: no yes | Enable/Disable MED comparison on paths from different autonomous systems.
bestpath_aspath_multipath_relax boolean | Choices: no yes | Enable/Disable load sharing across the providers with different (but equal-length) AS paths.
bestpath_compare_neighborid boolean | Choices: no yes | Enable/Disable neighborid. Use this when more paths available than max path config.
bestpath_compare_routerid boolean | Choices: no yes | Enable/Disable comparison of router IDs for identical eBGP paths.
bestpath_cost_community_ignore boolean | Choices: no yes | Enable/Disable Ignores the cost community for BGP best-path calculations.
bestpath_med_confed boolean | Choices: no yes | Enable/Disable enforcement of bestpath to do a MED comparison only between paths originated within a confederation.
bestpath_med_missing_as_worst boolean | Choices: no yes | Enable/Disable assigns the value of infinity to received routes that do not carry the MED attribute, making these routes the least desirable.
bestpath_med_non_deterministic boolean | Choices: no yes | Enable/Disable deterministic selection of the best MED pat from among the paths from the same autonomous system.
cluster_id - |  | Route Reflector Cluster-ID.
confederation_id - |  | Routing domain confederation AS.
confederation_peers - |  | AS confederation parameters.
disable_policy_batching boolean | Choices: no yes | Enable/Disable the batching evaluation of prefix advertisement to all peers.
disable_policy_batching_ipv4_prefix_list - |  | Enable/Disable the batching evaluation of prefix advertisements to all peers with prefix list.
disable_policy_batching_ipv6_prefix_list - |  | Enable/Disable the batching evaluation of prefix advertisements to all peers with prefix list.
enforce_first_as boolean | Choices: no yes | Enable/Disable enforces the neighbor autonomous system to be the first AS number listed in the AS path attribute for eBGP. On NX-OS, this property is only supported in the global BGP context.
event_history_cli - | Choices: size_small size_medium size_large size_disable default | Enable/Disable cli event history buffer.
event_history_detail - | Choices: size_small size_medium size_large size_disable default | Enable/Disable detail event history buffer.
event_history_events - | Choices: size_small size_medium size_large size_disable default | Enable/Disable event history buffer.
event_history_periodic - | Choices: size_small size_medium size_large size_disable default | Enable/Disable periodic event history buffer.
fast_external_fallover boolean | Choices: no yes | Enable/Disable immediately reset the session if the link to a directly connected BGP peer goes down. Only supported in the global BGP context.
flush_routes boolean | Choices: no yes | Enable/Disable flush routes in RIB upon controlled restart. On NX-OS, this property is only supported in the global BGP context.
graceful_restart boolean | Choices: no yes | Enable/Disable graceful restart.
graceful_restart_helper boolean | Choices: no yes | Enable/Disable graceful restart helper mode.
graceful_restart_timers_restart - |  | Set maximum time for a restart sent to the BGP peer.
graceful_restart_timers_stalepath_time - |  | Set maximum time that BGP keeps the stale routes from the restarting BGP peer.
isolate boolean | Choices: no yes | Enable/Disable isolate this router from BGP perspective.
local_as - |  | Local AS number to be used within a VRF instance.
log_neighbor_changes boolean | Choices: no yes | Enable/Disable message logging for neighbor up/down event.
maxas_limit - |  | Specify Maximum number of AS numbers allowed in the AS-path attribute. Valid values are between 1 and 512.
neighbor_down_fib_accelerate boolean | Choices: no yes | Enable/Disable handle BGP neighbor down event, due to various reasons.
provider dictionary |  | Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli`. This option is only required if you are using NX-API. For more information please see the NXOS Platform Options guide. A dict object containing connection details.
| auth_pass string added in 2.5.3 |  | Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTH_PASS` will be used instead.
| authorize boolean added in 2.5.3 | Choices: no ← yes | Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_AUTHORIZE` will be used instead.
| host string / required |  | Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
| password string |  | Specifies the password to use to authenticate the connection to the remote device. This is a common argument used for either cli or nxapi transports. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_PASSWORD` will be used instead.
| port integer | Default: "0 (use common port)" | Specifies the port to use when building the connection to the remote device. This value applies to either cli or nxapi. The port value will default to the appropriate transport common port if none is provided in the task. (cli=22, http=80, https=443).
| ssh_keyfile string |  | Specifies the SSH key to use to authenticate the connection to the remote device. This argument is only used for the cli transport. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_SSH_KEYFILE` will be used instead.
| timeout integer | Default: 10 | Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error. NX-API can be slow to return on long-running commands (sh mac, sh bgp, etc).
| transport string / required | Choices: cli ← nxapi | Configures the transport connection to use when connecting to the remote device. The transport argument supports connectivity to the device over cli (ssh) or nxapi.
| use_proxy boolean added in 2.5 | Choices: no yes ← | If `no`, the environment variables `http_proxy` and `https_proxy` will be ignored.
| use_ssl boolean | Choices: no ← yes | Configures the transport to use SSL if set to `yes` only when the `transport=nxapi`, otherwise this value is ignored.
| username string |  | Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate either the CLI login or the nxapi authentication depending on which transport is used. If the value is not specified in the task, the value of environment variable `ANSIBLE_NET_USERNAME` will be used instead.
| validate_certs boolean | Choices: no yes ← | If `no`, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. If the transport argument is not nxapi, this value is ignored.
reconnect_interval - |  | The BGP reconnection interval for dropped sessions. Valid values are between 1 and 60.
router_id - |  | Router Identifier (ID) of the BGP router VRF instance.
shutdown boolean | Choices: no yes | Administratively shutdown the BGP protocol.
state - | Choices: present ← absent | Determines whether the config should be present or not on the device.
suppress_fib_pending boolean | Choices: no yes | Enable/Disable advertise only routes programmed in hardware to peers.
timer_bestpath_limit - |  | Specify timeout for the first best path after a restart, in seconds.
timer_bgp_hold - |  | Set BGP hold timer.
timer_bgp_keepalive - |  | Set BGP keepalive timer.
vrf - |  | Name of the VRF. The name 'default' is a valid VRF representing the global BGP.

## Notes

Note

- Tested against NXOSv 7.3.(0)D1(1) on VIRL
- `state=absent` removes the whole BGP ASN configuration when `vrf=default` or the whole VRF instance within the BGP process when using a different VRF.
- Default when supported restores params default value.
- Configuring global params is only permitted if `vrf=default`.
- For information on using CLI and NX-API see the NXOS Platform Options guide
- For more information on using Ansible to manage network devices see the Ansible Network Guide
