hi,
i just prepared a christmas present for you:

rare/freerouter just got colorful vrfs, and it exports and imports from bgp 
ctp afi...
tbh it was not too hard at all, i just reused the vrf class afterall... :)
https://github.com/rare-freertr/freeRtr/commit/f0eb1bc325b5a2d1c58d670b22a7fc44d8a29850

i'll add some test cases covering the import/export in a later commit... :)
okk, i also need to be able to parse the color:100 extcomm in the vrf config, 
also later...
and yeahh, the backup rt thing is also missing at the moment... :)
and finally, i really need to deal with the flex algo topologies from the 
igps... :)

but heyy, if you wish, we could show them an other round of interop on the 
next ietf,
and at this time, freerouter could go without the outer ldp label imho... :)
for now, rare/freertr could do an 
---[ebgp]----asbr1--[ibgp]---asbr2----[ebgp]---
where you dont need ldp in between the asbr12...
br,
cs
