neighbor open-delay

This command sets the interval between the establishment of a TCP connection and the sending of an OPEN message to open a BGP session.

Syntax

neighbor ip-address open-delay seconds
no neighbor ip-address open-delay seconds

Parameters

ip-address Specifies a BGP peer as a valid IPv4 address in dotted-quad format or as a valid IPv6 address in colon-separated format.
seconds Specifies the interval, in seconds, between the establishment of a TCP connection and the sending of an OPEN message to open a BGP session. Valid values are 0 - 240 seconds. The default value is 0 seconds (no delay).

Defaults

None.

Mode

BGP Router Configuration.

Usage

The BGP OPEN message is used to open a BGP session, and is sent after the TCP handshake is completed. The delay set by this command allows the remote BGP peer time to send the first OPEN message.

Use the no neighbor open-delay command to reset the delay between the TCP handshake completion and the sending of the BGP OPEN message to the default value of 0 seconds (no delay).

Example

The following example sets the delay between TCP handshake completion and the sending of the OPEN message to 3 seconds:

System(su-config)->router bgp 65151
System(su-config-bgp)->bgp router-id 159.1.1.9
System(su-config-bgp)->neighbor 9.1.2.1 open-delay 3
System(su-config-bgp)->
