[dev] FRR vrf, multi-instance

[Jia Chen]

Hi All, 

A question about FRR way of supporting vrf, multi-instance, or logical router. 

A. OSPF/IS-IS multi-instance is a control plane concept, not forwarding
B. VRF is both routing and forwarding, for example, L3vpn and EVPN, which uses RT, RD in BGP updates
C. Virtual router is a non-VPN instance, which does not require RT, RD

Both B and C, has a one-to-one interface to routing instance mapping. 

Are A, B, C all supported by FRR? 

Juniper has a logical system (or router), which divided physical router into logical sub-routers. Each logical router has dedicated interface, routing protocols, routing and forwarding table. Are there equivalent in FRR? 

Thanks,
Jay
