Municipal security wants multicast for one tenant contained so it does not leak into other tenants' broadcast domains. What EVPN-VXLAN principle applies?
Select an answer to reveal the explanation.
Short Explanation
Each tenant VNI is its own multicast neighborhood—keep the noise inside that broadcast domain. Do not build one megaphone for every VRF or flatten everyone into VLAN 1. Type-4 is about Ethernet Segments, not merging tenant multicast universes.
Full Explanation
In EVPN-VXLAN, BUM and multicast scope align with the VNI/tenant L2 broadcast domain (and related L3 VRF separation for routed multicast designs). Sharing one tree across all VNIs or collapsing tenants into a single VLAN defeats isolation. Type-4 ES routes support multihoming, not intentional merging of tenant multicast domains.
