Comment 1 Enji Cooper freebsd_committer freebsd_triage 2017-03-18 18:39:10 UTC 
You need to load mib-II to get the missing symbol. This is an issue with several of the MIB modules not lazy-loading their dependencies. I think this was noted in the example config file/module manpage, but I'll doublecheck. I'll see if I can at the very least add more intuitive error messages.
Comment 2 Enji Cooper freebsd_committer freebsd_triage 2017-03-18 18:40:35 UTC 
Also, you must load mib-II in the config before the bridge module.

Thanks.
Moving a section

#
# MIB-2 module
#
begemotSnmpdModulePath."mibII"  = "/usr/lib/snmp_mibII.so"

just above the boot section of the snmp_bridge.so module in the config snmpd.conf started  service bsnmpd.

Probably, it is necessary to make the appropriate corrections in the installation config snmpd.conf

I forgot to MFC the change from head that moved MIB-II being loaded before the bridge module. Fixed in r315592/r315593.

I'll open another bug to fix the underlying issue that needs to be fixed is more apparent.
