and verifying this using

* Why has SNMP support been disabled?
=====================================

+Frr used to link against the NetSNMP libraries to provide SNMP
support. Those libraries sadly link against the OpenSSL libraries
to provide crypto support for SNMPv3 among others.
OpenSSL now is not compatible with the GNU GENERAL PUBLIC LICENSE (GPL)

would requite the affirmation of all people that ever contributed

"copyright holder". That's too much work. Using a shrinked down
version of NetSNMP without OpenSSL or convincing the NetSNMP people
to change to GnuTLS are maybe good solutions but not reachable
*BUT*
It is allowed by the used licence mix that you fetch the sources and
