Huawei S1720 Series Configuration Guide

Context
After BGP initiates a TCP connection, the ConnectRetry timer will be stopped if the TCP
connection is established successfully. If the first attempt to establish a TCP connection fails,
BGP tries again to establish the TCP connection after the ConnectRetry timer expires.
l Setting a short ConnectRetry interval reduces the period BGP waits between attempts to
establish a TCP connection. This speeds up the establishment of the TCP connection.
l Setting a long connectRetry interval suppresses routing flapping caused by peer relationship
flapping.
A ConnectRetry timer can be configured either for all peers or peer groups, or for a specific peer
or peer group. A ConnectRetry timer configured for a specific peer takes precedence over that
configured for the peer group of this peer. In addition, a ConnectRetry timer configured for a
specific peer or peer group takes precedence over that configured for all peers or peer groups.
Procedure
l Configure a BGP ConnectRetry timer for all peers or peer groups.
Perform the following steps on a BGP switch:
1. Run:
system-view
The system view is displayed.
2. Run:
bgp as-number
The BGP view is displayed.
3. Run:
timer connect-retry connect-retry-time
A BGP ConnectRetry timer is configured for all peers or peer groups.
By default, the ConnectRetry timer value is 32s.
l Configure a ConnectRetry timer for a specific peer or peer group.
Perform the following steps on a BGP switch:
1. Run:
system-view
The system view is displayed.
2. Run:
bgp as-number
The BGP view is displayed.
3. Run:
peer { group-name | ipv4-address } timer connect-retry connect-retry-time
A ConnectRetry timer is configured for a specific peer or peer group.
By default, the ConnectRetry timer value is 32s.
