frr_bgp – Configure global BGP settings on Free Range Routing(FRR)

New in version 2.8.

Synopsis

• This module provides configuration management of global BGP parameters on devices running Free Range Routing(FRR).

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.
			maximum_prefix integer		Maximum number of prefixes to accept from this peer. The range is from 1 to 4294967295.
			neighbor - / required		Neighbor router address.
			next_hop_self boolean	Choices: no yes	Enable/disable the next hop calculation for this neighbor.
			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.
			route_server_client boolean	Choices: no yes	Specify a neighbor as a route server client.
		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.).
			network - / required		Network ID to announce via BGP.
			route_map -		Route map to modify the attributes.
		redistribute -			Specifies the redistribute information from another routing protocol.
			id -		Specifies the instance ID/table ID for this protocol Valid for ospf and table
			metric -		Specifies the metric for redistributed routes.
			protocol - / required	Choices: ospf ospf6 eigrp isis table static connected sharp nhrp kernel babel rip	Specifies the protocol for configuring redistribute information.
			route_map -		Specifies the route map reference.
		safi -		Choices: flowspec unicast ← multicast labeled-unicast	Specifies the type of cast for the address family.
	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.
		advertisement_interval integer			Minimum interval between sending BGP routing updates for this neighbor.
		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 boolean		Choices: no yes	Administratively shutdown or enable a neighbor.
		local_as integer			The local AS number for the neighbor.
		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.
		port integer			The TCP Port number to use for this neighbor. The range is from 0 to 65535.
		remote_as integer / required			Remote AS of the BGP neighbor to configure.
		timers -			Specifies BGP neighbor timer related configurations.
			holdtime integer / required		Interval (in seconds) after not receiving a keepalive message that FRR declares a peer dead. The range is from 0 to 65535.
			keepalive integer / required		Frequency (in seconds) with which the FRR sends keepalive messages to its peer. The range is from 0 to 65535.
		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.
	router_id -				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.
