MAC-VRFs

This chapter introduces the concept of a MAC-VRF. A MAC-VRF, like an IP VRF, is rooted in multitenancy and creates virtual forwarding tables, specifically for MAC addresses in this case. This allows for logical separation of tenants in an EVPN VXLAN fabric, providing better control of Layer 2 segmentation in the overlay.

A MAC-VRF is bound to an EVPN Instance, commonly called EVI, that spans multiple PEs (VTEPs). MAC-VRFs are configured on Junos using the routing instance construct. Each MAC-VRF has a bridge table (or multiple tables) corresponding to a broadcast domain (or domains) in that MAC-VRF. With MAC-VRFs, flooding of traffic within the fabric is also optimized, with BUM traffic replicated only to the VTEPs that are ...
