This is a map of our WAN router and the upstream ISP. I added the upstream ISP as an ICMP only node and the Border Router as SNMP. I haven't asked, but I'm fairly certain the ISP won't let me monitor their router with SNMP to get the topology data from it. Is this why I can't get link utilization? I'm polling L2 and L3 topology on the Border Router but NPM can't seem to make the connection. The ISP is directly connected.
Is there anything I can do here to use the link utilization?
