If delay-time is not specified, the default delay (0 seconds) is used. This means that a BGP device
tears down the connection with a peer immediately after detecting the peer unreachable.
A proper delay-time value can ensure network stability.

After the BGP network convergence speed is adjusted, you can view information about BGP
peers and peer groups.
Prerequisites
Adjusting the BGP network convergence speed has been configured.

on BGP peers must be greater than the IGP route convergence time. Otherwise, if IGP route
flapping occurs, the BGP peer relationship will be interrupted before network convergence
is complete.
NOTE
IGP GR is configured and a BGP peer relationship is established based on an IGP route. If a device
becomes faulty and performs an active/standby switchover, the IGP will not delete routes received by
the device. As a result, the BGP peer relationship will not be interrupted, even through BGP peer
tracking does not take effect.
standby switchover, the delay-time values on the BGP peers must be greater than the GR
time. Otherwise, the BGP peer relationship will be interrupted before the GR time expires.
As a result, GR becomes invalid.
Run the display bgp peer [ verbose ] command to check information about BGP peers.
Run the display bgp group [ group-name ] command to check information about BGP
peer groups.
