neighbor timers
Set keepalive and hold time timers for a BGP neighbor or a peer group.
Syntax
neighbor {ip-address | peer-group-name} timers keepalive
holdtime
To return to the default values, use the no neighbor {ip-address | peer-
group-name} timers command.
Parameters
ip-address Enter the IP address of the peer router in dotted decimal
format.
peer-group-
name
Enter the name of the peer group to set the timers for all
routers within the peer group.
keepalive Enter a number for the time interval, in seconds, between
keepalive messages sent to the neighbor routers. The range
is from 1 to 65535. The default is 60 seconds.
holdtime Enter a number for the time interval, in seconds, between
the last keepalive message and declaring the router dead.
The range is from 3 to 65535. The default is 180 seconds.
Defaults
• keepalive = 60 seconds
• holdtime = 180 seconds

History
Version 9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
Timer values configured with the neighbor timers command override the timer
values configured with any other command.
When two neighbors, configured with different keepalive and holdtime values,
negotiate for new values, the resulting values are as follows:
• the lower of the holdtime value is the new holdtime value, and
• whichever is the lower value; one-third of the new holdtime value, or the
configured keepalive value, is the new keepalive value.
neighbor update-source
Enable the software to use Loopback interfaces for TCP connections for BGP sessions.
