Router Discovery vs IPAM-driven subnet population

Hello All,

 

I am looking for perspectives from the community on Router Discovery vs IPAM-driven subnet population.

If an enterprise already has authoritative IPAM (e.g., Infoblox) and imports subnets via the Infoblox Service Graph Connector, what are the practical benefits of also running Router Discovery?

Specifically:

  • What additional value does Router Discovery provide beyond subnet ranges (topology, relationships, validation)?

  • What are the risks of running both (duplicate subnet CIs, reconciliation challenges)?

  • Can Router Discovery be configured to relate to existing subnets without creating new ones?

  • Does Router Discovery create subnets/IPs that are largely unused?

  • For those using Infoblox SGC: is subnet import straightforward, and how are Discovery schedules operationalized by location or region? Is this manual or automated?

Interested in real-world experience and architectural guidance.

 

Thank you,

Praveen
