Hi all, I'm working on sonic-frr, which is just frr. I enable frr-snmp, and follow this (http://docs.frrouting.org/en/latest/snmp.html) to get trap, this is my configuration:

root@NX-ZWYC-M1F202-A16-HW6865-A-INT-212:/# cat /etc/snmp/snmptrapd.conf # # EXAMPLE-trap.conf: # An example configuration file for configuring the Net-SNMP snmptrapd agent. #

############################################################################### # # This file is intended to only be an example. # When the snmptrapd agent starts up, this is where it will look for it. # # All lines beginning with a '#' are comments and are intended for you # to read. All other lines are configuration commands for the agent. disableAuthorization yes # # PLEASE: read the snmptrapd.conf(5) manual page as well! # #authCommunity log,execute,net private #authCommunity log,execute,net public #authCommunity log,execute,net snmp@sankuai # traphandle .1.3.6.1.2.1.15.0.1 ./bgp-peer-status traphandle .1.3.6.1.2.1.15.0.2 ./bgp-peer-status

root@NX-ZWYC-M1F202-A16-HW6865-A-INT-212:/# cat ./bgp-peer-status #!/bin/bash echo `cat -`

Then I up/down bgp peer use these command:

NX-ZWYC-M1F202-A16-HW6865-A-INT-212(config-router)# router bgp 65003 NX-ZWYC-M1F202-A16-HW6865-A-INT-212(config-router)# neighbor 192.168.10.9 shutdown NX-ZWYC-M1F202-A16-HW6865-A-INT-212(config-router)# no neighbor 192.168.10.9 shutdown

This is trap message I got, I got 2 messages, you could see, the 2 message is the same, especially in bgp peer status, I guess this is a BUG ?
