The conf/bgpneighbors directory contains configuration files for BGP neighbors. The name of a file is the name of the neighbor configuration that it defines. BGP neighbors can be managed under the System > Fault Tolerance > BGP Neighbors section of the Admin UI, or by using functions under the BGPNeighbors section of the SOAP API and CLI.

| Key                      | Description                                                                                                                                                                                                                                                                          |

| address                  | The IP address of the BGP neighbor<br />Value type: string<br />Default value: \<none>                                                                                                                                                                                               |
| advertisement\_interval  | The minimum interval between the sending of BGP routing updates to neighbors. Note that as a result of jitter, as defined for BGP, the interval during which no advertisements are sent will be between 75% and 100% of this value.<br />Value type: seconds<br />Default value: "5" |
| as\_number               | The AS number for the BGP neighbor<br />Value type: unsigned integer<br />Default value: "65534"                                                                                                                                                                                     |

| holdtime                 | The period after which the BGP session with the neighbor is deemed to have become idle - and requires re-establishment - if the neighbor falls silent.<br />Value type: seconds<br />Default value: "90"                                                                             |
| keepalive                | The interval at which messages are sent to the BGP neighbor to keep the mutual BGP session established.<br />Value type: seconds<br />Default value: "30"                                                                                                                            |
