Command Reference Guide
hold-timer <value>
Use the hold-timer command to set the default hold time for all neighbors in the Border Gateway Protocol
(BGP) process on either the default or nondefault VPN routing and forwarding (VRF) instance.
Syntax Description
<value>
Default Values
By default, the hold time is 180 seconds.
Command History
Release 8.1
Release 18.3
Functional Notes
The hold-timer command can be used to specify the hold timer for BGP neighbors on either the default or
nondefault VRF instance. If the behavior is to be created on a nondefault VRF instance, the VRF instance
must first be created using the command
configured the nondefault VRF instance, you can configure the BGP settings for the VRF instance using
the command vrf <name> on page 2877
configure the BGP characteristics for the nondefault VRF instance RED1, enter the following commands:
(config)#vrf RED1 route-distinguisher ip 192.17.250.24:33
(config)#router bgp 100
(config-bgp)#vrf RED1
(config-bgp-vrf)#
For more information about VRF and Multi-VRF BGP configuration, refer to the configuration guides
Configuring IPv4 Multi-VRF in AOS (article number 2156) and Configuring BGP in AOS for Releases
18.03.00/R10.1.0 or Later (article number 3524) available online at https://supportforums.adtran.com.
Using the hold-timer command in BGP configuration mode sets the default hold time for all neighbors in
that BGP process. Using the hold-timer command in BGP Neighbor Configuration mode sets the hold
time for only that neighbor. The peers will negotiate and use the lowest configured setting. The keepalive
interval will be set to one-third of the negotiated hold time.
Usage Examples
The following example sets a hold time of 120 seconds for a specific neighbor, with an understood
keepalive interval of 40 seconds on the default VRF instance:
(config)#router bgp 100
(config-bgp)#hold-timer 120
60000CRG0-35E
Specifies a time interval (in seconds) within which a keepalive must be
received from a peer before that peer is declared dead. Range is 0 to
65535 seconds.
