I've run into a problem when trying to use IPv6 without IPv4. With an IPv4 address configured, I can use IPv6 with either a static address or using DHPCv6 and everything works fine. If I configure a static IPv6 address, everything is fine. However, if when I try to use DHCPv6 without IPv4, both my dhcp client and the eCos radv6 daemon report "no route to host" failures trying to send. I believe they're both trying to send link-local multicast packets and failing because the interface doesn't have a link local address. How do I get the network stack to create and configure an IPv6 link-local address for the interface. It seems that configuring the interface with a static IPv6 address does that as a "side effect". How do I get that to happen without configuring a static IPv6 address? -- Grant Edwards grant.b.edwards Yow!
