I'm having some trouble understanding your questions, but the modules<br>
are installed to /usr/lib/*/frr/modules/*_snmp.so and loaded at startup<br>
with the "-M snmp" option.<br>

<br>
Then the frr-snmp package is not installed. There is no problem with<br>
the build process. Unless you modify the Debian package - or the<br>
package build didn't complete successfully - SNMP support is enabled for<br>
Debian packages.<br>

<br>
There is nothing to change to enable SNMP support in Debian packages.<br>
You just need to install the frr-snmp package and add the "-M snmp" /<br>
"--module snmp" (same option) to your config.<br>

<br>
You seem to have that in place already since you're getting the<br>
"zebra_snmp.so not found" error.<br>
