Ops enables OSPF as the underlay for a small municipal pod instead of BGP. How should that choice be understood at concept level?
Select an answer to reveal the explanation.
Short Explanation
Small pod, simple map—OSPF can be the underlay GPS instead of BGP. It is a real option, not a certification crime. You still need those loopbacks reachable; OSPF does not invent free overlay discovery.
Full Explanation
IP fabric underlays may use an IGP such as OSPF, particularly in smaller pods, as an alternative to EBGP or IBGP designs. Protocol choice does not remove the need for infrastructure prefix reachability, including VTEP loopbacks when overlays are used. Claims that Juniper fabrics forbid IGPs, or that OSPF is spine-only with static leaves, overstate constraints. Evaluate scale, policy, and operational fit when choosing underlay routing.
