Just FYI: on OpenBSD you can set the VRF (aka "routing table" or
"routing domain") per socket with code like this:

  int s, table;
  s = socket(...);
  table = 123;
  setsockopt(s, IPPROTO_IP, SO_RTABLE, &table, sizeof(table));

 
Or exec your commands wrapped in route -T$TABLE exec $*

Caveat: ipv6 vrf's did not work the last time I tried, and I think they
still don't.

The fix for that was committed to HEAD recently. I think it's going to
be part of 5.0 or 5.1. Effectively it means s/IPPROTO_IP/SOL_SOCKET/ in
the example code above.
