Success.
DGS-3620-28SC:admin#
13-25 config bgp neighbor timer
Description
This command is used to configure the BGP neighbor’s timer attribute.
advertisement_interval: If an advertised route is flapping, this usually occurs when an interface is
unstable, a lot of UPDATE and WITHDRAWN messages will be sent. One method to control the
flooding of these messages is to set a minimum advertisement interval.
Format
config bgp neighbor timer [<ipaddr> | peer_group <peer_group_name 16>]
{advertisement_interval [<sec 0-600> | default] | [keepalive <sec 0-65535> holdtime <sec 0-
65535> | default_keepalive_holdtime] | as_origination_interval [<sec 1-600> | default] |
connect [<sec 1-65535> | default]}(1)
Parameters
<ipaddr> - Specifies the IP address of the neighbor to be configured.
peer_group - Specifies the peer group to be configured.
<peer_group_name 16> - Enter the peer group name here. This name can be up to 16
characters long.
advertisement_interval - (Optional) It specifies the interval at which the BGP process sends
update messages to its peer. If this value is set to zero, the update or withdrawn message will
be sent immediately. The default value for IBGP peers is 5 seconds and for EBGP peers it is
30 seconds. When it is specified to default, the neighbor specific advertisement interval setting
will be returned to the default setting.
<sec 0-600> - Enter the advertisement interval value here. This value must be between 0 and
600 seconds.
default - Specifies that the advertisement interval will be set to default.
keepalive - (Optional) This specifies the interval at which a keepalive message is sent to its
peers. If the two routers, that build BGP connection, have different keepalive timers, the
smaller keepalive timer will be used. If the keepalive is set to zero, then the keepalive
message will not be sent out. By default, the timer is not specified. This neighbor specific
setting will follow the global setting.
<sec 0-65535> - Enter the keep alive value here. This value must be between 0 and 65535.
holdtime - (Optional) The system will declare a peer as dead if not receiving a keepalive
message until the hold time. If two routers, that builded a BGP connection, have different hold
times, the smaller hold time will be used. If the holdtime is zero, then the holdtime will never
expire. It is recommended that the holdtime value is 3 times that of keepalive timer. By default,
the timer is not specified. This neighbor specific setting will follow the global setting.
<sec 0-65535> - Enter the hold time value here. This value must be between 0 and 65535.
default_keepalive_holdtime - (Optional) Clear the specification of the neighbor specific holdtime
and keepalive setting.
as_origination_interval - (Optional) Minimum interval between the sending AS origination
routing updates. The valid value is from 1 to 600. The default setting is 15 seconds.
<sec 1-600> - Enter the AS original interval value here. This value must be between 1 and
600.
