Consider this DHCPv6 network configuration (subnets have been changed to nonsense):
shared-network SomeNetwork {
preferred-lifetime 77760;
default-lease-time 86400;
subnet6 1234:4321:105:8000::/50 {
}
subnet6 1234:4321:10b:4000::/50 {
prefix-length-mode prefer;
pool6 {
range6 1234:4321:10b:6000::1 1234:4321:10b:7fff:ffff:ffff:ffff:fffe;
prefix6 1234:4321:259:: 1234:4321:259:fff0:: /60;
}
}
}
We had previously had pool6{} range6{} and prefix6{} configurations in 1234:4321:105:8000::/50 Somehow these two devices continue to renew their prefix delegation and ip allocation:

There are no host declarations or anything for these hosts. There were several other hosts in the subnet/prefix who successfully moved to the new subnet/prefix.
Thoughts?
