The following configuration works for my environment, using Mac address for
ipv6 reservations
- on the dhcp client side after installing the node, I force the use of the
DUID-LL and the setting dhcp6.method = auto (if I remember correctly it is used
to set the routing correctly)
nmcli connection modify <iface> ipv6.dhcp-duid ll
nmcli connection modify <iface> ipv6.method auto
- on the kea dhcp server with the following option I can used the Mac address
for ipv6 reservations
- "mac-sources": [ "client-link-addr-option", "ipv6-link-local”] —> I’ve
configured relay agent on router so ipv6-link-local should not be used
- "host-reservation-identifiers": ["hw-address”]
- example of host reservations
{
"hostname": “<fqdn>",
"hw-address": “00:00:00:00:00:00",
"ip-addresses": [“abcd:abcd::7"]
} ,
Hope this help,
Cristina
