Hello everybody.
I'm trying to setup dhcpv6 kea server to answer dhcp relayed queries
My unicast ipv6 address, that i want to answer queries, is binded to some
"dummy" interface.
Here is network config:
# ip -6 ad 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen
1000 inet6 ::1/128 scope host valid_lft forever preferred_lft
forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP
qlen 1000 inet6 fd27:7c53:761b:30:10:76:136:12/64 scope global
valid_lft forever preferred_lft forever inet6
fe80::21a:4aff:fe08:131/64 scope link valid_lft forever
preferred_lft forever 3: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500
state UNKNOWN qlen 1000 inet6 fd7c:99:66:40::1:1/128 scope global
valid_lft forever preferred_lft forever inet6
fe80::80eb:33ff:fe28:cb15/64 scope link valid_lft forever
preferred_lft forever And here is simple kea config: {"Dhcp6": {
"interfaces-config": { "interfaces":
["dummy0/fd7c:99:66:40::1:1"], }, "lease-database": {
"type": "memfile", "persist": true, "name":
"/var/lib/kea/dhcp6.leases" }, "min-preferred-lifetime": 3600,
"preferred-lifetime": 3600, "max-preferred-lifetime": 3600,
"min-valid-lifetime": 7200, "valid-lifetime": 7200,
"max-valid-lifetime": 7200, "t1-percent": 0.5, "t2-percent":
0.8, "option-data": [ { "name": "dns-servers",
"code": 23, "space": "dhcp6",
"csv-format": true, "data":
"fd7c:99:66:41:72ec:1::1, fd7c:99:66:41:72ec:1::2" }, ],
"subnet6": [ { "subnet": "fdc4:130:234:7::/64",
"pools": [ { "pool":
"fdc4:130:234:7::10-fdc4:130:234:7::50" } ]
} ] }} But when i try to ask server via dhcpv6 relay (network
equipment) its print in logs error:
INFO [kea-dhcp6.dhcp6/1402481.140706201806400] DHCP6_QUERY_LABEL

DHCP6_PACKET_SEND_FAIL failed to send DHCPv6 packet: Interface eth0/2
does not have any suitable IPv6 sockets open. I understand that for some
reason it wants this unicast address to be binded to normal interface,
and when i bind it to "eth0" it answers and all work OK. May be i have
some misconfig, but i want to be able to bind this unicast IPv6 address
to some logical interfaces in order to have anycast setup with multiple
nics. P.S. i have tried 2.2, 2.4 and 2.5 versions of kea, all with same
problem.
