Step 3 Run:
peer { ipv6-address | group-name } timer keepalive keepalive-time hold hold-time
The interval for sending Keepalive messages and the Hold time of a peer (or peer group) are set.
In actual applications, the value of hold-time is at least three times that of keepalive-time.
By default, the Keepalive time is 60s and the Hold time is 180s.
Note the following when you set the values of keepalive-time and hold-time:
l When the values of keepalive-time and hold-time are 0 at the same time, the BGP timer
l The value of hold-time is far greater than that of keepalive-time, such as, timer keepalive 1

8.6.3 Setting the BGP4+ ConnectRetry Interval

You can speed up or slow down the establishment of BGP4+ peer relationships to adapt the
network changes by changing the BGP4+ ConnectRetry interval.
Context
When 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. The
ConnectRetry interval can be adjusted as needed.

NOTE
Setting the hold interval of a BGP peer to be longer than 20s is recommended. If the hold interval of a BGP
peer is shorter than 20s, the session may be closed.
becomes invalid. That is, BGP does not detect link faults according to the timer.
hold 65535. If the Hold time is too long, the link fault cannot be detected on time.
The ConnectRetry interval can be reduced in order to lessen the time BGP4+ 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 speed up route convergence.
Set a ConnectRetry interval globally.
