## Synopsis

- This module provides configuration management of global BGP parameters on Arista EOS devices.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
config - |  | Specifies the BGP related configuration.
| address_family - |  | Specifies BGP address family related configurations.

afi
- / required

Choices:
- ipv4
- ipv6

Type of address family to configure.

|  | neighbors - |  | Specifies BGP neighbor related configurations in Address Family configuration mode.

activate
boolean

Choices:
- no
- yes

Enable the Address Family for this Neighbor.

default_originate
boolean

Choices:
- no
- yes

Originate default route to this neighbor.

graceful_restart
boolean

Choices:
- no
- yes

Enable/disable graceful restart mode for this neighbor.

|  |  | neighbor - / required |  | Neighbor router address.
|  |  | weight integer |  | Assign weight for routes learnt from this neighbor. The range is from 0 to 65535
|  | networks - |  | Specify Networks to announce via BGP. For operation replace, this option is mutually exclusive with root level networks option.
|  |  | masklen - |  | Subnet mask length for the Network to announce(e.g, 8, 16, 24, etc.).
|  |  | prefix - / required |  | Network ID to announce via BGP.
|  |  | route_map - |  | Route map to modify the attributes.
|  | redistribute - |  | Specifies the redistribute information from another routing protocol.
|  |  | protocol - / required |  | Specifies the protocol for configuring redistribute information.
|  |  | route_map - |  | Specifies the route map reference.
| bgp_as integer / required |  | Specifies the BGP Autonomous System (AS) number to configure on the device.

log_neighbor_changes
boolean

Choices:
- no
- yes

Enable/disable logging neighbor up/down and reset reason.

| neighbors - |  | Specifies BGP neighbor related configurations.
|  | description - |  | Neighbor specific description.
|  | ebgp_multihop integer |  | Specifies the maximum hop count for EBGP neighbors not on directly connected networks. The range is from 1 to 255.
|  | enabled - |  | Administratively shutdown or enable a neighbor.
|  | maximum_prefix integer |  | Maximum number of prefixes to accept from this peer. The range is from 0 to 4294967294.
|  | neighbor - / required |  | Neighbor router address.
|  | password - |  | Password to authenticate the BGP peer connection.
|  | peer_group - |  | Name of the peer group that the neighbor is a member of.
|  | remote_as integer / required |  | Remote AS of the BGP neighbor to configure.

remove_private_as
boolean

Choices:
- no
- yes

Remove the private AS number from outbound updates.

route_reflector_client
boolean

Choices:
- no
- yes

Specify a neighbor as a route reflector client.

|  | timers - |  | Specifies BGP neighbor timer related configurations.
|  |  | holdtime integer / required |  | Interval (in seconds) after not receiving a keepalive message that device declares a peer dead. The range is from 3 to 7200. Setting this value to 0 will not send keep-alives (hold forever).
|  |  | keepalive integer / required |  | Frequency (in seconds) with which the device sends keepalive messages to its peer. The range is from 0 to 3600.
|  | update_source - |  | Source of the routing updates.
| networks - |  | Specify Networks to announce via BGP. For operation replace, this option is mutually exclusive with networks option under address_family. For operation replace, if the device already has an address family activated, this option is not allowed.
|  | masklen - |  | Subnet mask length for the Network to announce(e.g, 8, 16, 24, etc.).
|  | prefix - / required |  | Network ID to announce via BGP.
|  | route_map - |  | Route map to modify the attributes.
| redistribute - |  | Specifies the redistribute information from another routing protocol.
|  | protocol - / required |  | Specifies the protocol for configuring redistribute information.
|  | route_map - |  | Specifies the route map reference.
| router_id - | Default: null | Configures the BGP routing process router-id value.

operation
-

Choices:
- merge ←
- replace
- override
- delete

Specifies the operation to be performed on the BGP process configured on the device.
In case of merge, the input configuration will be merged with the existing BGP configuration on the device.
In case of replace, if there is a diff between the existing configuration and the input configuration, the existing configuration will be replaced by the input configuration for every option that has the diff.
In case of override, all the existing BGP configuration will be removed from the device and replaced with the input configuration.
In case of delete the existing BGP configuration will be removed from the device.
