[Kea-users] Fwd: KEA 1.1.0 and cassandra cluster

[Lex Ivanov]

Thank you, Andrei,

That helped. But now I have to use only keyspace 'keatest', so the option
"name" does not work. Otherwise I'm getting:

1484223384.208 [ERROR] (src/pool.cpp:388:virtual void
cass::Pool::on_close(cass::Connection*)): Connection pool was unable to
connect to host 192.168.144.133 because of the following error: Received
error response 'Keyspace 'keatest' does not exist' (0x02002200)
2017-01-12 16:16:24.213 ERROR [kea-dhcp4.dhcp4/10010] DHCP4_INIT_FAIL
failed to initialize Kea server: configuration error using file
'/usr/local/etc/kea/kea.conf': Unable to open database: could not connect
to DB reason: Keyspace 'keatest' does not exist error code: 16777231

And concerning the second question:
yes, I'm using

"interfaces-config": {
    "interfaces": [ "eth0", "eth1" ]
},

But I want Kea to send 'default router' 10.4.0.1 to clients on eth0 and
10.5.0.1 to clients on eth1.
Is it possible?
