peer timer connect-retry (BGP-VPN instance IPv4 address family 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

A ConnectRetry interval can be configured globally, or on a particular peer group. A ConnectRetry interval configured on a specific peer group takes precedence over a global ConnectRetry interval.

If both the peer { ipv4-address | ipv6-address } timer connect-retry connect-retry-time command and the peer group-name timer connect-retry connect-retry-time command are run on a device, the configuration of the peer { ipv4-address| ipv6-address } timer connect-retry connect-retry-time command takes effect, but the configuration of the peer group-name timer connect-retry connect-retry-time command does not.
If both the peer { group-name | ipv4-address | ipv6-address } timer connect-retry connect-retry-time command and the timer connect-retry connect-retry-time command are run on a device, the configuration of the peer { group-name | ipv4-address | ipv6-address } timer connect-retry connect-retry-time command takes effect, but the configuration of the timer connect-retry connect-retry-time command does not.

Example

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