[Nobumichi.Ozoe at jp.yokogawa.com]

Hi all,

dibbler-server ouput the following error log.

55:09 Server Error     Unable to find relay interface with interfaceID=6
defined on the eth0/2 interface.

Then, dibbler server A (dibbler version 0.6.1) can't reply the
RELAY-REPLY message.

Please tell me what's wrong.

1. Network topology is as follows:

            Dibbler server A (dibbler version 0.6.1) 
                   |
---------+---------+---
         |
         | B1
   DHCPv6 relay agent B
         | B2
         |
---------+---------+--
                   |
            DHCPv6 client C 

2. Dibbler-server configuration is as follows:

# cat /etc/dibbler/server.conf
log-level 8
log-mode short
stateless
iface relay1 {
 relay eth0
 interface-id 5020
 option sip-server 3ffe:ff2::2
}

3. Dibbler-server debug log on dibbler server A is as follows:

Address part is modified.
