This solution allows delivery of both IPv4 and IPv6 multicast traffic in an IP-VRF using an IPv6 multicast in the underlay network. The protocol used to build multicast trees in the underlay network is IPv6 PIM-SSM.

This feature makes a switch act as a neighbor discovery proxy for an IPv6 subnets. It can be used in conjunction with BUM

IS IS area proxy allows the creation of more scalable networks. IS IS already has hierarchical mechanisms for

Selective ARP install is the selective programming of remote ARPs in hardware as received through EVPN Type 2 MAC-IP routes in an EVPN VXLAN/ MPLS Integrated Routing and Bridging (IRB) scenario. Instead of installing every MAC+IP binding received from EVPN into the hardware, the switch installs them only when there is routed traffic destined to the IP, thereby saving TCAM space on the switch. However, there is a tradeoff as there is an initial one-time latency to install the hardware TCAM entry on the first flow of routed traffic to the IP.

Enabling “Proxy ARP/ND for Single Aggregation (AG) VTEP Campus Deployments without EVPN” allows an aggregation VTEP to proxy reply to a VXLAN-encapsulated ARP request/NS when the ARP/NS target host is remote and the ARP/ND binding is already learned by the AG VTEP.

IPv6 Duplicate Address Detection Proxy is a proxy-based mechanism allowing the use of Duplicate Address Detection (DAD) by IPv6 nodes in a point-to-multipoint architecture with a "split-horizon" forwarding scheme. In Split-horizon scenario where the hosts can not directly communicate with each other, but only through a BNG (Broadband Network Gateway).
