New in version 2.8.


Synopsis

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

-

Specifies BGP address family related configurations.

afi

- / required

  • ipv4
  • ipv6

Type of address family to configure.

neighbors

-

Specifies BGP neighbor related configurations in Address Family configuration mode.

activate

boolean

  • no
  • yes

Enable the address family for this neighbor.

  • yes

Specify a neighbor as a route reflector client.

route_server_client

boolean

  • no

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.).

Specifies the instance ID/table ID for this protocol

Valid for ospf and table

metric

-

Specifies the metric for redistributed routes.

protocol

bgp_as

integer / required

Specifies the BGP Autonomous System (AS) number to configure on the device.

log_neighbor_changes

boolean

  • 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

-

ebgp_multihop

integer

Specifies the maximum hop count for EBGP neighbors not on directly connected networks.

The range is from 1 to 255.

integer

The local AS number for the neighbor.

neighbor

- / required

Neighbor router address.

password

-

Password to authenticate the BGP peer connection.

integer

The TCP Port number to use for this neighbor.

The range is from 0 to 65535.

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

-

Default:

null

Configures the BGP routing process router-id value.

operation

-

  • 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.



Notes

Note

  • Tested against FRRouting 6.0.
