This feature provides the ability to interconnect EVPN VXLAN domains. Domains may or may not be within the same data center network, and the decision to stretch/interconnect a subnet between domains is configurable. The following diagram shows a multi-domain deployment using symmetric IRB. Note that two domains are shown for simplicity, but this solution supports any number of domains.

This feature adds control plane support for inter-subnet forwarding between EVPN networks. This support is achieved by advertising received EVPN IP Prefix routes (Type-5) with next-hop self. VXLAN and MPLS encapsulation are supported, and the encapsulation type used for advertised routes is dependent on the encapsulation type configured for EVPN peering. The following diagram shows an example topology where an EVPN VXLAN network exchanges Type-5 routes with an EVPN MPLS network.

VXLAN flood lists are typically configured via CLI or learned via control plane sources such as EVPN. The

Configuration of VXLAN overlay using EVPN allows for extension of Layer 2 (L2) or Layer 3 (L3) networks across
