EVPN-MPLS: EVPN and MC-LAG interworking

You can use Ethernet VPN (EVPN) to extend your Junos Fusion Enterprise or MC-LAG network over an MPLS network. Typically, Junos Fusion Enterprise is extended to a geographically distributed campus or enterprise network, while an MC-LAG network is extended to a data center network or geographically distributed campus or enterprise network. The EVPN-MPLS interworking feature offers the following benefits:

• Ability to use separate virtual routing and forwarding (VRF) instances to control inter-VLAN routing
• VLAN translation
• Default Layer 3 virtual gateway support, which eliminates the need to run such protocols as Virtual Router Redundancy Protocol (VRRP)
• Load balancing to better utilize both links when using EVPN multihoming
• The use of EVPN type 2 advertisement routes (MAC+IP) reduces the need for flooding domains with ARP packets

Note that we don't support the core isolation feature with active/active EVPN-MPLS and active/active MC-LAG interworking.
