EVPN VXLAN Ingress Replication
The EVPN VXLAN Ingress Replication feature enables the VXLAN tunnel endpoint (VTEP) to exchange
local and remote VTEP IP addresses on the Virtual Network Identifier (VNI) in order to create the ingress
replication list. This enables VTEPs to send and receive broadcast, unknown unicast and multicast (BUM)
traffic for the VNI. These IP addresses are exchanged between VTEPs through the BGP EVPN control plane
using EVPN Route Type 3. This feature enables in reduced traffic flooding, increased load sharing at VTEP,
faster convergence during link and device failures, and simplified data center automation.
The VXLAN imposition node maintains a list of remote VTEP nodes that serve the same tenant VNI. Each
copy of VXLAN packet is sent to the destination VTEP through underlay L3 unicast transport. EVPN Route
Type 3 which is a inclusive multicast route, is used to build a replication list of VXLAN data plane VTEPs.
The imposition node replicates BUM traffic for each remote VTEP node discovered by this route. Each copy
of VXLAN is sent to destination VTEP through underlay L3 unicast transport. The ASR 9000 router is a DC
edge router, which works as DCI gateway by stitching two MP-BGP control planes, one on the DC side, and
the other on the MPLS WAN side.
Following are the use cases of this feature:
