LMS 4.1 Topology fail

Can you please check and confirm that the devices can see each other via CDP? ("show cdp neighbor" on each device.)

Well if the routers themselves can't see the neighbors, LMS (which after all only queries the snmp mibs to get its information) certainly won't!

I believe you need to explicitly enable CDP on the FR-facing interfaces of your routers - a global "cdp run" command won't flow down to affect FR interface behavior.

There is also the possibility that your provider won't handle / pass the CDP layer 2 multicasts but first try explicitly adding "cdp enable" on your FR-facing interfaces.
