Understanding Virtual Routing Instances on EX Series Switches
Virtual routing instances allow administrators to divide a Juniper Networks EX Series Ethernet Switch into multiple independent virtual routers, each with its own routing table. Splitting a device into many virtual routing instances isolates traffic traveling across the network without requiring multiple devices to segment the network.
You can use virtual routing instances to isolate customer traffic on your network and to bind customer-specific instances to customer-owned interfaces.
Virtual routing and forwarding (VRF) is often used in conjunction with Layer 3 subinterfaces, allowing traffic on a single physical interface to be differentiated and associated with multiple virtual routers. Each logical Layer 3 subinterface can belong to only one routing instance.
EX Series switches support IPv4 and IPv6 unicast and multicast VRF traffic. See EX Series Switch Software Features Overview for details on VRF support by switch per Junos OS release.
