Change windows routinely edit underlay BGP and overlay EVPN together across the whole civic fabric with no canary leaves. What best practice should replace that pattern?
Select an answer to reveal the explanation.
Short Explanation
Changing the roads and the tunnel maps on every block at once is how you get a city-wide outage. Canary a few leaves, validate routes and VTEPs, then roll—underlay and overlay both.
Full Explanation
Professional fabric operations separate blast radius: stage underlay and overlay changes, use canary devices, and validate sessions, routes, and VTEP reachability before broad deployment. Simultaneous fabric-wide dual-plane edits without validation increase outage risk. Rebooting all spines first or skipping checks outside Apstra environments is not sound practice.
