Configuring BGP Services
5-43
Parameter: Holdtime
Default: 90 seconds
Range: 0 or any decimal number greater than 2
Function: Specifies the holdtime that will be inserted into an Open message. Upon
receipt of the peer’s Open message, the lesser of the two holdtimes will be
used (this must be at least 3 seconds). There are two exceptions:
• If one peer sends a zero holdtime, then the non-zero holdtime is used.
• If both peers send zero holdtimes, then no holdtime is used.
The calculated holdtime is the amount of time either peer will wait for a
Keepalive or Update message before declaring the connection down.
Instructions: Either accept the current Holdtime Timer value or set the parameter to 0
or some value greater than 2 seconds.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.5.1.2.1.13
Parameter: Keepalive Timer
Default: 30 seconds
Options: Any decimal number
Function: Specifies how often Keepalive messages will be sent across this peer
connection.
If a holdtime of 0 is negotiated, no periodic Keepalive messages are sent.
Otherwise, the Keepalive timer is set to the smaller of this configured
value and one-third of the holdtime.
Instructions: Either accept the current Keepalive value or set this parameter to some
value greater than 0.
