peer timer connect-retry (BGP-VPN instance view) (group)

Function

The peer timer connect-retry command sets a ConnectRetry interval for a peer group.

The undo peer timer connect-retry command restores the default setting.

By default, the ConnectRetry interval is 32s.

Format

peer group-name timer connect-retry connect-retry-time

undo peer group-name timer connect-retry

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.
connect-retry-time	Specifies a ConnectRetry interval.	The value ranges from 1 to 65535, in seconds.

Usage Guidelines

Usage Scenario

When BGP initiates a TCP connection, the ConnectRetry timer is stopped if the TCP connection is established successfully. If the attempt to establish a TCP connection fails, BGP tries again to establish the TCP connection after the ConnectRetry timer expires. The ConnectRetry interval can be adjusted as needed.

The ConnectRetry interval can be reduced in order to lessen the time BGP waits to retry establishing a TCP connection after the first attempt fails.
To suppress route flapping caused by constant peer flapping, the ConnectRetry interval can be increased to accelerate route convergence.

Prerequisites

The peer as-number command has been used to create a peer group.

Precautions

BGP supports the configuration of the connection retransmission interval for a single neighbor, a peer group, and the entire system. The priority of the connection retransmission interval for a single peer takes precedence over a global configuration. To change the retransmission interval of a specified peer or peer group, run this command.

If both the peer {ipv4-address | ipv6-address} timer connect-retry connect-retry-time and peer group-name timer connect-retry connect-retry-time commands are run on a device and the peer belongs to the peer group, the peer does not inherit the configuration of the peer group.
If both the peer {group-name | ipv4-address | ipv6-address} timer connect-retry connect-retry-time and timer connect-retry connect-retry-time commands are run on a device, the peer or peer group does not inherit the global configuration.

Example

# Set the ConnectRetry interval to 60s for peer group.
