To clarify this, Juniper M-series/T-series running JUNOS use VRFs. In addition they also (in JUNOS 6.x and higher) have the concept of Logical Routers which are separate routing tables but are not necessarily associated with IPVPNs. Juniper also has the capability for VRFs in the ERX (or E-series) product, and the creation of "virtual routers' (or VRs). You could use a combination of virtual routers which VRFs inside them, for further separation of routing information. This might be used for carrier of carrier solutions. On the ERX-1440 (40Gbps fabric) you can create: 1000 Virtual Routers, 16,384 stacked vlans per line card, or 32,768 total vlans per chassis, and 64,000 ATM VCs per chassis. Generally you can service 16,000 pvs per ATM line card. You can carry about 1 million MPLS next-hops, and 1 million IPv4 routes.
