Comprehensive and Detailed Explanation:
BGP EVPN Type 3 routes are used for VXLAN ingress replication and BUM (Broadcast, Unknown unicast, and Multicast) traffic forwarding.
# Type 3 routes contain L2VNIs, not L3VNIs # (C is incorrect)
Key Functions of Type 3 Routes:
* Distribute VTEP IP addresses to establish VXLAN tunnels.
* Include L2VNIs for mapping Layer 2 broadcast domains.
* Used in Ingress Replication for BUM traffic.
Since Type 3 routes do not carry L3VNIs, the correct answer is C.
