Multihoming in EVPN allows a single customer edge (CE) to connect to multiple provider edges (PE or tunnel endpoint). In any multihoming EVPN instance (EVI), for each ethernet segment a designated forwarder is elected using EVPN type 4 Ethernet Segment (ES) routes sent through BGP. In single-active mode, the designated forwarder (DF) is responsible for sending and receiving all traffic. In all-active mode, the DF is only used to determine whether broadcast, unknown

EOS currently supports EVPN Multicast by setting up PIM tunnels in the underlay with VXLAN as the transport. While this is an efficient delivery mechanism, it requires PIM to be deployed in the underlay. In certain cases, the overheads of provisioning/maintaining the multicast routers and the multicast routing state in the underlay may be significant.

In EVPN, an overlay index is a field in type-5 IP Prefix routes that indicates that they should resolve indirectly rather than using resolution information contained in the type-5 route itself. Depending on the type of overlay index, this resolution information may come from type-1 auto discovery or type-2 MAC+IP routes. For this feature the gateway IP address field of the type-5 NLRI is used as the overlay index, which matches the target IPv4 / IPv6 address in the type-2 NLRI.

Ethernet VPN (EVPN) networks normally require some measure of redundancy to reduce or eliminate the impact of outages and maintenance. RFC7432 describes four types of route to be exchanged through EVPN, with a built-in multihoming mechanism for redundancy. Prior to EOS 4.22.0F, MLAG was available as a redundancy option for EVPN with VXLAN, but not multihoming. EVPN multihoming is a multi-vendor standards-based redundancy solution that does not require a dedicated peer link and allows for more flexible configurations than MLAG, supporting peering on a per interface level rather than a per device level. It also supports a mass withdrawal mechanism to minimize traffic loss when a link goes down.
