peer route-update-interval
Function
The peer route-update-interval command sets the interval at which a device sends routing updates carrying the same prefix to a peer or peer group.
The undo peer route-update-interval command restores the default setting.
By default, the interval at which routing updates are sent to IBGP peers is 15s, and the interval at which routing updates are sent to EBGP peers is 30s.
Format
peer { group-name | ipv4-address | ipv6-address } route-update-interval interval
undo peer { group-name | ipv4-address | ipv6-address } route-update-interval
Parameters
| Parameter | Description | Value |
|---|---|---|
| group-name | Specifies the name of a peer group. | The name is a string of 1 to 47 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| ipv4-address | Specifies the IPv4 address of a peer. | It is in dotted decimal notation. |
| ipv6-address | Specifies the IPv6 address of a peer. | The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. |
| interval | Specifies the minimum interval at which routing updates are sent. | The value is an integer that ranges from 0 to 600, in seconds. |

Usage Guidelines
Usage Scenario
When routes change, the switch sends routing updates to notify its peers. If a route changes frequently, the peer route-update-interval command can be used to adjust the interval at which Update packets are sent for changes of this route. This frees the switch from sending Update packets for every route change.
Prerequisites
If the peer route-update-interval command is used but no peer exists, a message is displayed, indicating that the peer does not exist.
Precautions
If a route is withdrawn, the switch immediately sends an Update message to its peers, regardless of the peer route-update-interval configuration. If a route is added and the interval between the last route addition time and the current route addition time is greater than the interval configured using the peer route-update-interval command, the switch immediately sends an Update message to its peers. If a route is added and the interval between the last route addition time and the current route addition time is less than the interval configured using the peer route-update-interval command, the switch sends an Update message to its peers only after the configured interval expires.
