learning on any community VLANs, you must configure
each of those VLANs.

Virtual routing instances allow administrators to divide a J-EX Series 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.
J-EX Series switches support IPv4 and IPv6 unicast and multicast VRF traffic.
J-EX4200 Series Ethernet Switches support up to 252 IPv4 virtual routing instances and
up to 64 IPv6 virtual routing instances. J-EX8200 Series Ethernet Switches support up
to 252 IPv4 and IPv6 virtual routing instances.
