While focused on SNMPv3, a blog post I wrote describes the mechanism for monitoring logical systems and routing instances from NMSes. There's a note at the end about SNMP version 2c but I've not tested it.

I have a Juniper MX204 router running 18.2R3-S5.3 with one Logical System. I successfully added the main system to the NMS using an SNMP trap. However, when I tried to add SNMP community on logical system I couldn't find the command to set snmp community public
I have search and tried various references on Google, but I haven't been successful. Can someone help me?
