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]
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.
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.
