Can someone please explain the concept of device discovery via Routing Table and BGP? I have 300+ remote networks, typically a router and a switch connected to the HQ via provider MPLS VPN. BGP is the protocol used. From the HQ WAN router perspective, it will not see any of these network devices as CDP neighbors. The WAN router do see all the remote networks in BGP and Route table. I am looking for a solution without having to manually add 750+ network devices.
I've added 1 of the networks in the Seed Device Settings and that network was discovered via CDP without any problem. I am also trying to avoid this approach, cuz I would have to add 300+ devices in my Seed Device Settings.
Thanks in advance.
