EVPN Type 5 Route with MPLS encapsulation for EVPN-MPLS

EVPN is a flexible solution that uses Layer 2 overlays to interconnect multiple edges (virtual machines) within a data center. Traditionally, the data center is built as a flat Layer 2 network with issues such as flooding, limitations in redundancy and provisioning, and high volumes of MAC addresses learned, which cause churn at node failures. EVPN is designed to address these issues without disturbing flat MAC connectivity.

The MPLS infrastructure allows you to take advantage of the MPLS functionality provided by the Junos operating system (Junos OS), including fast reroute, node and link protection, and standby secondary paths.

Starting with Junos OS Release 17.1, to support the interconnection through EVPN Type 5 route in the metro service application using EVPN/MPLS, an MPLS tunnel is required instead of a VXLAN tunnel.


L3VPN forwarding based on pure Type 5 without overlay next-hop is only supported.

In the control plane EVPN Type 5 is used to advertise IP prefix for inter-subnet connectivity across metro peering points. To reach the end host through the connectivity provided by the EVPN Type 5 prefix route, data packets are sent out as an IP packet encapsulated in the MPLS across the metro peering points.
