Step Command Remarks
5. Enter system view. system-view N/A
6. Enter BGP view. bgp as-number N/A
7. Enable compatibility with
routers not compliant with RFC
3065 in the confederation. confederation nonstandard
Optional
Not enabled by default
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 output rules of the traps (whether to output the
traps and the output direction) are determined according to the information center configuration. (For
information center configuration, see System Management and Maintenance Configuration Guide.)
To enable Trap:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable Trap for BGP. snmp-agent trap enable bgp
Optional.
Enabled by default.
Enabling logging of peer state changes
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Enable the logging of peer state
changes globally.
log-peer-change
Optional.
Enabled by default.
4. Enable the logging of peer state
changes for a peer or peer
group.
peer { group-name | ip-address }
log-change Optional.
Enabled by default.
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
mechanism makes link failure detection rather slow; 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.
To enable BFD for a BGP peer:
