Perhaps (I will search for this / seems also interesting for another case ;) ), but, in this case : # route -n show -inet6|grep "^2"|wc -l 44 and all routes are learned by dynamic routing (RIPng and BGP). Only one of the 8 network interfaces seems to have a problem with MTU. That's why I try to set it, on this network interface and on IPv6 only. Christophe.
