Configuring Bgp4+ Timers - Huawei S6700 Series Configuration Manual

S6700 Series Ethernet Switches
Configuration Guide - IP Routing
A ConnectRetry timer is used to set the interval between BGP4+ attempts to initiate TCP
connections. After BGP4+ initiates a TCP connection, the ConnectRetry timer is stopped if the
TCP connection is established successfully. If the first attempt to establish a TCP connection
fails, BGP4+ tries again to establish the TCP connection after the ConnectRetry timer expires.
You can speed up or slow down the establishment of BGP4+ peer relationships by changing the
BGP4+ ConnectRetry interval. For example, if the ConnectRetry interval is reduced, BGP4+
will wait less time to retry establishing a TCP connection when an earlier attempt fails. This
speeds up the establishment of the TCP connection. If a BGP4+ peer flaps constantly, the
ConnectRetry interval can be increased to suppress route flapping caused by BGP4+ peer
flapping. This speeds up route convergence.
Pre-configuration Tasks
Before configuring the parameters of a connection between BGP4+ peers, complete the
following tasks:

8.6.2 Configuring BGP4+ Timers

Configuring timers properly can improve network performance. Changing the values of BGP4
+ timers will interrupt the peer relationship.
Context
As the change of the timer (with the peer timer command) tears down the BGP peer relationship
between switches. Exercise caution when running this command.
Do as follows on the BGP4+ switch:
