In the context of internet scale routing a requirement that always
comes up is the need to partition the available routing tables into
disjoint routing planes. A specific use case is the multi-tenancy
problem where each tenant has their own unique routing tables and in
the very least need different default gateways.
This is an attempt to build the ability to create virtual router
domains aka VRF's (VRF-lite to be specific) in the linux packet
forwarding stack. The main observation is that through the use of
rules and socket binding to interfaces, all the facilities that we
need are already present in the infrastructure. What is missing is a
handle that identifies a routing domain and can be used to gather
applicable rules/tables and uniqify neighbor selection. The scheme
used needs to preserves the notions of ECMP, and general routing
principles.

I'm still opposed to name this 'vrf', see the v1 thread:

Shrijeet seemed to agree to rename it, is there a problem?
