neighbor advertisement-interval

This command sets the minimum interval between the sending of EBGP routing updates.

Syntax

neighbor ip-address advertisement-interval interval
no neighbor ip-address advertisement-interval

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.
interval Specifies the interval in seconds between the sending of BGP routing updates. Valid values are 1 - 65535 seconds. The default value is 30 seconds.

Defaults

None.

Mode

BGP Router Configuration.

Usage

BGP sends an UPDATE or WITHDRAWN message whenever an advertised EBGP route changes unless a minimum EBGP advertisement-interval setting is set. The flapping of an EBGP route can cause the flooding of UPDATE and WITHDRAWN messages. The EBGP advertisement-interval setting determines the frequency of EBGP updates regardless of changes to advertised EBGP routes.

The no neighbor advertisement-interval command resets the BGP advertisement-interval to the default value of 30 seconds.

Example

The following example sets the BGP advertisement interval for neighbor 9.1.2.1 to 35 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 advertisement-interval 35
System(su-config-bgp)->
