A municipal EVPN design uses a route-target community so only matching VRFs import a tenant's Type-2 and Type-5 routes. What does that extended community primarily control?
Select an answer to reveal the explanation.
Short Explanation
Route targets are membership badges for the tenant club — import only if your badge matches. That decides which VRF/VNI pulls in the EVPN routes, not IGP costs, VXLAN ports, or ZTP order. Wrong club, no routes.
Full Explanation
In MBGP EVPN, route targets are BGP extended communities that define import and export policy for EVPN routing instances. Matching RTs steer which PE/VTEP VRFs accept Type-2/Type-5 (and related) advertisements into a given tenant context. Underlay metrics, VXLAN UDP ports, and ZTP sequencing are orthogonal to RT-based membership.
