I have a setup where I'm trying to just use DHCPv6 for address assignment. I've got the following on my RA and from my understanding "managed-configuration" is supposed to set the M bit and I've confirmed that this is set from a wireshark trace but the client is still also receiving an address from slaac. Is this normal? I thought the M bit was supposed to tell the client to get all its info from DHCPv6.
show protocols router-advertisement
interface irb.406 {
managed-configuration;
prefix xxxx:xxxx:xxxx:xxxx::/64;
}
