As described in the Multi-VTEP MLAG TOI, singly connected hosts can lead to suboptimal peer-link utilization. By adding a local VTEP to each MLAG peer, the control plane is able to advertise singly connected hosts as being directly behind a specific local VTEP / MLAG peer.

In order to achieve split horizon and prevent double-delivery of packets in an MLAG setup, egress ACLs are installed on all active MLAG interfaces so that BUM traffic received on the MLAG peer-link cannot get forwarded out any MLAG interfaces. When only one half of an MLAG interface is active, this egress ACL is removed to allow BUM traffic from the peer-link to be forwarded out MLAG interfaces.

On a MLAG chassis, MAC addresses learned on individual peers are synced and appropriate interfaces are mapped to these MAC addresses. In case of unexpected events like reloading of one of the peers in the MLAG chassis or flapping of one or more MLAG interfaces, some loss of traffic may be observed.

In conventional VXLAN deployments, each MLAG pair of switches are represented as a common logical VTEP. VXLAN traffic can be decapsulated on either switch. In some networks, there are hosts that are singly connected to one of the MLAG pair.

Multicast VRF leak allows multicast traffic from a sender in one domain or VRF to be forwarded to a different domain or VRF, in which the receivers are connected. In the rest of this document, the VRF to which the multicast sender belongs to is referred to as the “source VRF” and the VRF that the multicast receiver belongs to is referred to as the “receiver VRF”.

NAT Peer State Synchronization feature provides redundancy and resiliency for Dynamic NAT across a pair of devices in an attempt to mitigate the risk of single NAT device failure. Each switch advertises connection state updates to its peer. State update consists of connection creation, connection state change (TCP mostly) or connection tear down
