connection reset can be disabled in such a situation. BGP will delete direct EBGP sessions on
the interface until the hold timer expires. This suppresses BGP network flapping, helps to
implement rapid BGP network convergence, and reduces network bandwidth consumption.
Perform the following steps on a BGP switch.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp as-number
The BGP view is displayed.
Step 3 Run:
undo ebgp-interface-sensitive
Rapid EBGP connection reset is disabled.
NOTE
Rapid EBGP connection reset is disabled in a situation where the status of an interface used to establish
an EBGP connection changes frequently. If the status of the interface becomes stable, run the ebgp-
interface-sensitive command to enable rapid EBGP connection reset to implement rapid BGP network
convergence.

7.12.6 Enabling BGP Tracking
BGP tracking can be used to adjust the interval between peer unreachability discovery and
connection interruption. This suppresses BGP peer relationship flapping caused by route
flapping and improves BGP network stability.
Context
BGP can be configured to detect peer relationship status changes in order to implement rapid
BGP convergence. BFD, however, needs to be configured on the entire network, and has poor
extensibility. If BFD cannot be deployed on a device to detect BGP peer relationship status,
BGP tracking can be enabled on the device to quickly detect link or peer unreachability,
implementing rapid network convergence.
Perform the following steps on a BGP switch.
Procedure
Step 1 Run:

The system view is displayed.
Step 2 Run:
