I don’t believe there is a MIB that will give you vxlan to interface mappings. The EVPN data can be extracted from SNMP, but it only tells you the existence of the vxlan/vni and the Mac addresses/IP’s present on that L2, it will not give you the port mappings. Juniper would prefer you use streaming telemetry or netconf to get this type of information since there isn’t a standard for representing this data in SNMP, other than the BGP-VPN-MIB, where you are basically parsing the TLV’s directly from BGP.

Subject: [External Mail] [Observium] EVPN / table support for vlans/vxlan

I'm running observium against a number of Juniper QFX5130's here.  We have
EVPN configured and vlans on the box which map to VXLAN in the evpn.  We see
no VLANs or EVPN data in observium.  Is there any support for this, as with
everything moving EVPN, we just have no visibility into the routing tables /
VRFs on the network.

Thanks,
