said configuration result report means is further arranged for generating invalid configuration report information to the non-preset node when the answer message is not received.

9. A control device according to claim 7, wherein said address configuration update message at least includes one of:

address of an added node;

address of a deleted node; and

address of an updated node.

10. A control device according to claim 7, wherein said address configuration update message further includes:

the group address of the anycast group; and

addresses of each node of the anycast group updated.

11. A method for assistant configuration of the non-preset nodes within an anycast group, comprising:

automatically performing address configuration based on an address configuration message or address configuration update message from a preset node within the anycast group, said automatically performing address configuration comprising;

i. receiving the address configuration message or address configuration update message from said preset node;

ii. configuring the present node based on the address configuration message or address configuration update message, said address configuration message or address configuration update message comprising;

a group address of the anycast group; and

address of each node of the anycast group, said automatically performing address configuration further comprising;

iii. generating an answer message based on the address configuration message;

iv. sending the answer message to the preset node, wherein said step iii comprises;

determining whether the configuration in said step ii is successful;

generating a “

Successful Configuration”

answer message if the configuration in said step ii is successful; and

generating an “

Invalid Configuration”

answer message containing a reason for invalid configuration if the configuration in said step ii is invalid.

12. A method according to claim 11, wherein said address configuration message at least includes:

the group address of the anycast group; and

addresses of each node of the anycast group.

13. A method according to claim 11, wherein said automatically performing address configuration comprises:

saving the addresses for all nodes, including the preset node, other than the present node within the anycast group to communicate with the present node, as contained in the address configuration message, to be correlated with the group address of the anycast group contained in the address configuration message.

14. A method according to claim 11, wherein said address configuration update message at least includes one of:
