[mpls-linux-general] VRF for Linux

[Nick E. <ni...@dc...>]

As part of Cisco's MPLS implementation, they introduced a feature called
VPN Routing/Forwarding (or Virtual Route Forwarding) referred to as VRFs
[or maybe this is an RFC definition].

What work is being done for Linux to support this concept?
In particular, making sure that ARP caches and FIBs can be VRFed.

In addition, is the VRF-aware versions of gated or zebra?

How about VRF-tagging of sockets or processes, to perform the same
functions as the cisco commands:

telnet x.x.x.x /vrf name
ping vrf name x.x.x.x
traceroute vrf name x.x.x.x

Per-VRF nat, filtering, etc??

Can anyone help?

Thanks!

VRF- Virtual Route Forwarding. Initially, a router has only one global
default routing/forwarding table. VRFs can be viewed as multiple disjoined
routing/forwarding tables, where the routes of a user have no correlation
with the routes of another user.

A VRF defines the VPN membership of a customer site attached to a PE
router. A VRF consists of an IP routing table, a derived Cisco Express
Forwarding (CEF) table, a set of interfaces that use the forwarding table,
and a set of rules and routing protocol parameters that control the
information that is included into the routing table
