Allied Telesis VERSION 5.4.3-2.6 manual Neighbor timers BGP and BGP4+

BGP and BGP4+ Commands

neighbor timers (BGP and BGP4+)

Use this command to set the keepalive, holdtime, and connect timers for a specific BGP or BGP4+ neighbor.

Use the no variant of this command to clear the timers for a specific BGP or BGP4+ neighbor.

Syntax [BGP/BGP4+] neighbor <neighborid> timers

{<keepalive> <holdtime>connect <connect>} no neighbor <neighborid> timers [connect]

Parameter Description

<neighborid> {<ip-address><ipv6-addr><peer-group>}

<ip-address>Specify the address of an IPv4 BGP neighbor, in dotted decimal notation A.B.C.D.

<ipv6-addr>Specify the address of an IPv6 BGP4+ neighbor, entered in hexadecimal in the format X:X::X:X.

<peer-group>Enter the name of an existing peer-group. For information on how to create peer groups, refer to the neighbor peer-group (add a neighbor) (BGP and BGP+) command on page 3.144, and neighbor route-map (BGP and BGP4+) command on page 3.159. When this parameter is used with this command, the command applies on all peers in the specified group.

<keepalive> <0-65535>Frequency (in seconds) at which a router sends keepalive messages to its neighbor. The default is 30 seconds as per RFC 4271. The default Cisco IOS keepalive timer is 60 seconds.

<holdtime> <0-65535>Interval (in seconds) after which, on not receiving a keepalive message, the router declares a neighbor dead. The default is 90 seconds as per RFC 4271. The default Cisco IOS keepalive timer is 180 seconds. Modify this value as needed for interoperability.

<connect> connect <1-65535>Specifies the connect timer in seconds. The default connect timer value is 120 seconds as per RFC 4271. Modify this value as needed for interoperability.

Default The keepalive timer default is 60 seconds, the holdtime timer default is 90 seconds, and the connect timer default is 120 seconds as per RFC 4271. Holdtime is keepalive * 3.

Mode [BGP] Router Configuration or IPv4 Address Family Configuration for a VRF instance

Mode [BGP4+] Router Configuration

Usage [BGP/BGP4+] Keepalive messages are sent by a router to inform another router that the BGP connection between the two is still active. The keepalive interval is the period of time between each keepalive message sent by the router. The holdtime interval is the time the router waits to receive a keepalive message and if it does not receive a message for this period it declares the neighbor dead. The holdtime value must be 3 times the value of the keepalive value.
