on Arista EOS devices.
notes:
- Tested against Arista vEOS Version 4.15.9M.
options:
config:
description:

type: int
required: true
router_id:
description:
- Configures the BGP routing process router-id value.
default: null
log_neighbor_changes:
description:
- Enable/disable logging neighbor up/down and reset reason.
type: bool
neighbors:
description:
- Specifies BGP neighbor related configurations.
suboptions:
neighbor:
description:

description:
- Remote AS of the BGP neighbor to configure.
type: int
required: True
update_source:
description:
- Source of the routing updates.
password:
description:
- Password to authenticate the BGP peer connection.
description:
description:
- Neighbor specific description.
ebgp_multihop:
description:
- Specifies the maximum hop count for EBGP neighbors not on directly connected networks.

suboptions:
keepalive:
description:
- Frequency (in seconds) with which the device sends keepalive messages to its peer.
- The range is from 0 to 3600.
type: int
required: True
holdtime:
description:
- 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).

description:
- Enable/disable graceful restart mode for this neighbor.
type: bool
weight:
description:
- Assign weight for routes learnt from this neighbor.
- The range is from 0 to 65535
type: int
operation:
description:
- 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.
