[Kea-users] DHCPv6: Host reservation by interface-id (18)

[perl-list]

I was able to hack around this (limitation?) (using some snippets found in earlier mailing list posts) with the following config.  
Please note that this will not work if there is more than one relay being done as it will probably be substring(relay6[some integer greater than 0].option[18].hex,0,all)

**** SNIP ****
        "client-classes": [
            {
                "name": "iid1",
                "test": "substring(relay6[0].option[18].hex,0,all) == 'Gi0/0/1.240'"
            }
        ],
**** SNIP ****
                "subnet6": [
                    {
                        "valid-lifetime": 600,
                        "preferred-lifetime": 500,
                        "subnet": "2001:0:2:e::/64",
                        "pools": [
                            {
                                "pool": "2001:0:2:e::2-2001:0:2:e::665"
                            },
                            {
                                "pool": "2001:0:2:e::666-2001:0:2:e::666",
                                "client-class": "iid1"
                            },
                            {
                                "pool": "2001:0:2:e::667-2001:0:2:e:7fff:ffff:ffff:fffe"
                            }
                        ],
**** SNIP ****
