Enabling Trap; Enabling Logging Of Peer State Changes; Configuring Bfd For Bgp - HP MSR2000 series Configuration Manual

Step
1. Enter system view.
2. Enable BGP and enter its view.
3. Enable GR Capability for BGP.
4. Configure the maximum time
allowed for the peer to
reestablish a BGP session.
5. Configure the maximum time to
wait for the End-of-RIB marker.

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 trap output rules (whether to output the traps
and the output direction) are determined according to the information center configuration. (For
information center configuration, see Network Management and Monitoring Configuration Guide.)
To enable trap:
Step
1. Enter system view.
2. Enable trap for BGP.

Enabling logging of peer state changes

Step
1. Enter system view.
2. Enter BGP view.
3. Enable the logging of peer
state changes globally.
4. Enable the logging of peer
state changes for a peer or
peer group.

Configuring BFD for BGP

BGP maintains neighbor relationships based on the keepalive timer and holdtime timer, which are set in
seconds. BGP defines that the holdtime interval must be at least three times the keepalive interval. This
slows down link failure detection; once a failure occurs on a high-speed link, a large quantity of packets
will be dropped. BFD is introduced to solve this problem. It detects links between neighbors quickly to
reduce convergence time upon link failures.
