Enabling Trap; Enabling Logging Of Session State Changes - HPE 5800 Series Configuration Manual

with the BGP routes already learned to complete BGP routing convergence. The GR Helper
then removes the state routes.
When you configure BGP GR, follow these guidelines:
•
GR Restarter sends the maximum time allowed for the peer to reestablish a BGP session to the
GR Helper in an Open message. When the GR Helper detects that the session to the GR
Restarter is down, it waits until the time advertised by the GR Restarter expires for a new
session to be established.
•
In general, the maximum time allowed for the peer to reestablish a BGP session must be less
than the Holdtime carried in the Open message.
•
The End-Of-RIB (End of Routing-Information-Base) indicates the end of route updates.
•
The maximum time to wait for the End-of-RIB marker configured on the local end is not
advertised to the peer; the setting is used to control the time on the local end to receive updates
from the peer end.
Perform the following configuration on the GR Restarter and GR Helper.
To configure BGP GR:
Step
Enter system view.
1.
Enable BGP, and enter its view.
2.

Enabling trap

After trap is enabled for BGP, BGP generates Level-4 traps to report important events. The
generated traps are sent to the information center of the device. The information center determines
whether to output the traps and where to output. For information center configuration, see Network
Management and Monitoring Configuration Guide.
To enable trap:
Step
Enter system view.
1.
Enable trap for BGP.

Enabling logging of session state changes

This task allows you to enable BGP to log session establishment and disconnection events. You can
use the display bgp ipv4 peer log-info command to view the log information.
To enable the logging of session state changes:
