Enabling Snmp Notifications For Bgp - HP VSR1000 Configuration Manual

the GR restarter updates its routing table and forwarding table with the BGP routes already
learned to complete BGP route convergence. The GR helper removes the stale routes.
Follow these guidelines when you configure BGP GR:
The End-Of-RIB 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. It controls the time for the local end to receive updates from the peer.
NOTE:

Perform the following configuration on the GR restarter and GR helper.
To configure BGP GR:
Step
1. Enter system view.
2. Enter BGP view.
3. Enable GR capability for BGP.

Enabling SNMP notifications for BGP

This feature enables generating SNMP notifications for BGP upon neighbor state changes, as defined in
RFC 4273. The SNMP notifications include the neighbor address, the code and subcode of the most
recent error, and the current neighbor state. The generated SNMP notifications are sent to the SNMP
module. The SNMP module determines how to output the notifications according to the configured output
rules.
For more information about SNMP notifications, see Network Management and Monitoring
Configuration Guide.
To enable SNMP notifications for BGP:
Step
1. Enter system view.
2. Enable SNMP notifications
