MAC VRF with EVPN-VXLAN

Data center service providers must support multiple customers with their own routing and bridging policies in the same physical network. To accommodate this requirement, you can now configure multiple customer-specific EVPN instances (EVIs) of type mac-vrf, each of which can support a different EVPN service type. This configuration results in customer-specific virtual routing and forwarding (VRF) tables with MAC addresses on each Juniper Networks device that serves as a virtual tunnel endpoint (VTEP) in the EVPN-VXLAN network.

To support this feature, we introduce a uniform routing instance configuration, which complies with RFC 7432, BGP MPLS-Based Ethernet VPN. The uniform configuration eliminates hardware restrictions

that limit the number of EVIs and combinations of EVIs with their respective policies that can simultaneously exist. The common configuration includes the following new CLI elements:

• The mac-vrf keyword at the [edit routing-instances name instance-type] hierarchy level.
• The service-type configuration statement at the [edit routing-instances name] hierarchy level. We support VLAN-based, VLAN-aware, and VLAN-bundle service types.
• The forwarding-instance configuration statement at the [edit routing-instances name] hierarchy level. With this optional configuration statement, you can map multiple routing instances to a single forwarding instance. If you don?t include this configuration statement, the default forwarding instance is used.

We continue to support the existing method of routing instance configuration along with the new uniform routing instance configuration.
