Arnaud,

  What are the other routers? Gentoo as well? same Quagga version?

   Without testing to see what exactly is going wrong I can only 
speculate. Could it be that the Gentoo box doesn't have support for 
network namespaces? and that is causing issues with Quagga trying to 
send vrf fields in RTM msgs? What do yo see if you do "ip netns list" on 
the router where you see this issue? is the output any different on 
other routers?
