EVPN Route Type 5 (IP Prefix Route) is used to advertise IP prefixes (subnets) between broadcast domains or between VRFs in an EVPN fabric.
IP-VRF-to-IP-VRF (Statement C):In an EVPN-VXLAN architecture, Type 5 routes are primarily used forLayer 3 connectivity. They allow different IP-VRFs on different VTEPs to exchange prefix information directly. This model is widely referred to asIP-VRF-to-IP-VRFrouting because it enables inter-subnet routing at the leaf layer without requiring Layer 2 MAC learning for those specific prefixes.
Overlay Next Hop (Statement B):For a PE router to reach a prefix advertised via a Type 5 route, it must resolve theoverlay next hop. This next hop is typically the loopback IP address of the originating VTEP, which the receiving router uses to build the VXLAN tunnel.
Why others are incorrect:Statement A is incorrect because Type 7 routes are used for IGMP/MLD join synchronization. Statement D is incorrect because Type 5 routes advertise IP prefixes, not MAC addresses; MAC extended communities are associated with Type 2 routes.
