I thought someone had to respond to router solicitations for stateless autoconfig of global scope addresses to happen. On Linux you just don't run the radvd. On Cisco I think it's something like "ipv6 nd suppress-ra" in the interface config. Does that fail to prevent stateless autoconfig? Or is there a problem with the operation of DHCPv6 if router advertisements aren't happening from the router? Regards, Bill Herrin -- William D.
