dellemc.enterprise_sonic.sonic_bgp_neighbors_af module – Manage the BGP neighbor address-family and its parameters

Note

This module is part of the dellemc.enterprise_sonic collection (version 2.5.1).

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 dellemc.enterprise_sonic.

To use it in a playbook, specify: dellemc.enterprise_sonic.sonic_bgp_neighbors_af.

New in dellemc.enterprise_sonic 1.0.0

Synopsis

• This module provides configuration management of BGP neighbors address-family parameters on devices running Enterprise SONiC.

• bgp_as, vrf_name and neighbors need be created in advance on the device.

Note

This module has a corresponding action plugin.

Parameters

Parameter	Comments
config list / elements=dictionary	Specifies the BGP neighbors address-family related configuration.
bgp_as string / required	Specifies the BGP autonomous system (AS) number which is already configured on the device.
neighbors list / elements=dictionary	Specifies BGP neighbor related configurations in address-family configuration mode.
address_family list / elements=dictionary	Specifies BGP address-family related configurations. afi and safi are required together.
activate boolean	Enables the address-family for this neighbor. Choices: false true
afi string / required	Type of address-family to configure. Choices: "ipv4" "ipv6" "l2vpn"
allowas_in dictionary	Specifies the allowas in values.
origin boolean	Specifies the origin value. Choices: false true
value integer	Specifies the value of the allowas in.
fabric_external boolean	Configure a neighbor as fabric-external. Fabric external is supported only for l2vpn address family. Choices: false true
ip_afi dictionary	Common configuration attributes for IPv4 and IPv6 unicast address families.
default_policy_name string	Specifies routing policy definition.
send_default_route boolean	Enable or disable sending of default-route to the neighbor. Choices: false ← (default) true
prefix_limit dictionary	Specifies prefix limit attributes for ipv4-unicast and ipv6-unicast.
max_prefixes integer	Maximum number of prefixes that will be accepted from the neighbor.
prevent_teardown boolean	Enable or disable teardown of BGP session when maximum prefix limit is exceeded. Choices: false ← (default) true
restart_timer integer	Time interval in seconds after which the BGP session is re-established after being torn down.
warning_threshold integer	Threshold on number of prefixes that can be received from a neighbor before generation of warning messages. Expressed as a percentage of max-prefixes.
prefix_list_in string	Inbound route filtering policy for a neighbor.
prefix_list_out string	Outbound route filtering policy for a neighbor.
route_map list / elements=dictionary	Specifies the route-map.
direction string	Specifies the direction of the route-map.
name string	Specifies the name of the route-map.
route_reflector_client boolean	Specifies a neighbor as a route-reflector client. Choices: false true
route_server_client boolean	Specifies a neighbor as a route-server client. Choices: false true
safi string	Specifies the type of cast for the address-family. Choices: "unicast" ← (default) "evpn"
neighbor string / required	Neighbor router address which is already configured on the device.
vrf_name string	Specifies the VRF name which is already configured on the device. Default: "default"
state string	Specifies the operation to be performed on the BGP process that is configured on the device. In case of merged, the input configuration is merged with the existing BGP configuration on the device. In case of deleted, the existing BGP configuration is removed from the device. Choices: "merged" ← (default) "deleted" "replaced" "overridden"
