Planners propose hundreds of routing instances on each leaf for tiny municipal departments. Beyond raw platform limits, what operational concern should they weigh?
Select an answer to reveal the explanation.
Short Explanation
Hundreds of mini-VRFs sound tidy until change control becomes a spreadsheet museum. Scale limits matter, but so does ops gravity: more instances mean more RT/RD landmines. Sometimes fewer, well-chosen tenants beat a VRF per broom closet.
Full Explanation
Routing-instance scale is both a platform limit and an operational complexity problem. Large counts amplify naming consistency needs, RT/RD uniqueness, troubleshooting surface, and blast radius of mis-imports. Absolute myths about automatic OSPF hello changes or hard 'eight instance' EVPN cliffs are not the lesson—design tenants to real isolation boundaries and validate platform scale.
