arista.eos.eos_bgp_address_family module – Manages BGP address family resource module

Note

This module is part of the arista.eos collection (version 6.2.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install arista.eos.

To use it in a playbook, specify: arista.eos.eos_bgp_address_family.

New in arista.eos 1.4.0

Synopsis

• This module configures and manages the attributes of BGP AF on Arista EOS platforms.

Parameters

Parameter	Comments
config dictionary	Configurations for BGP address family.
address_family list / elements=dictionary	Enable address family and enter its config mode
afi string	address family. Choices: "ipv4" "ipv6" "evpn"
bgp_params dictionary	BGP parameters.
additional_paths string	BGP additional-paths commands Choices: "install" "send" "receive"
next_hop_address_family string	Next-hop address-family configuration Choices: "ipv6"

redistribute_internal boolean	Redistribute internal BGP routes. Choices: false true
route string	Configure route-map for route installation.
graceful_restart boolean	Enable graceful restart mode. Choices: false true
neighbor list / elements=dictionary	Configure routing for a network.
activate boolean	Activate neighbor in the address family. Choices: false true
additional_paths string	BGP additional-paths commands. Choices: "send" "receive"
default_originate dictionary	Originate default route to this neighbor.
always boolean	Always originate default route to this neighbor. Choices: false true
route_map string	Route map reference.
encapsulation dictionary	Default transport encapsulation for neighbor. Applicable for evpn address-family.
source_interface string	Source interface to update BGP next hop address. Applicable for mpls transport.
transport string	MPLS/VXLAN transport. Choices: "mpls" "vxlan"
graceful_restart boolean	Enable graceful restart mode. Choices: false true
next_hop_address_family string	Next-hop address-family configuration Choices: "ipv6"
next_hop_unchanged boolean	Preserve original nexthop while advertising routes to eBGP peers. Choices: false true
peer string	Neighbor address/ peer group name.
prefix_list dictionary	Prefix list reference.
direction string	Configure an inbound/outbound prefix-list. Choices: "in" "out"
name string	prefix list name.
route_map dictionary	Route map reference.
direction string	Configure an inbound/outbound route-map. Choices: "in" "out"
name string	Route map name.
weight integer	Weight to assign.
network list / elements=dictionary	configure routing for network.
address string	network address.
route_map string	Route map reference.
redistribute list / elements=dictionary	Redistribute routes in to BGP.
isis_level string	Applicable for isis routes. Specify isis route level. Choices: "level-1" "level-2" "level-1-2"
ospf_route string	ospf route options. Choices: "internal" "external" "nssa_external_1" "nssa_external_2"
protocol string	Routes to be redistributed. Choices: "isis" "ospfv3" "dhcp"
route_map string	Route map reference.
route_target dictionary	Route target.
action string	Route action. Choices: "both" "import" "export"
imported_route boolean	Export routes imported from the same Afi/Safi Choices: false true
route_map string	Name of a route map.
target string	Route Target.
type aliases: mode string	Type of address fmaily Choices: "evpn" "vpn-ipv4" "vpn-ipv6"
safi string	Address family type for ipv4. Choices: "labeled-unicast" "multicast"
vrf string	name of the VRF in which BGP will be configured.
as_number string	Autonomous system number.
running_config string	This option is used only with state parsed. The value of this option should be the output received from the EOS device by executing the command show running-config | section bgp. The state parsed reads the configuration from running_config option and transforms it into Ansible structured data as per the resource module’s argspec and the value is then returned in the parsed key within the result.
state string	The state the configuration should be left in. Choices: "deleted" "merged" ← (default) "overridden" "replaced" "gathered" "rendered" "parsed"

Notes

Note

• Tested against Arista EOS 4.24.6F

• This module works with connection network_cli. See the EOS Platform Options.

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key	Description
after dictionary	The resulting configuration after module execution. Returned: when changed Sample: "This output will always be in the same format as the module argspec.\n"
before dictionary	The configuration prior to the module execution. Returned: when state is merged, replaced, overridden, deleted or purged Sample: "This output will always be in the same format as the module argspec.\n"
commands list / elements=string	The set of commands pushed to the remote device. Returned: when state is merged, replaced, overridden, deleted or purged Sample: ["router bgp 10", "address-family ipv4", "redistribute ospfv3 match external", "network 1.1.1.0/24"]
gathered dictionary	Facts about the network resource gathered from the remote device as structured data. Returned: when state is gathered Sample: "This output will always be in the same format as the module argspec.\n"
parsed dictionary	The device native config provided in running_config option parsed into structured data as per module argspec. Returned: when state is parsed Sample: "This output will always be in the same format as the module argspec.\n"
rendered list / elements=string	The provided configuration in the task rendered in device-native format (offline). Returned: when state is rendered Sample: ["router bgp 10", "address-family ipv4", "redistribute ospfv3 match external", "network 1.1.1.0/24"]
