Equipment is connect by judging oneself with whether purpose equipment establishes, to can determine whether the message to be forwarded
It is forwarded to purpose equipment.
Optionally, node device can traverse preset route table items, and by judge in route table items whether
There is the IP address of purpose equipment to match with the internal layer purpose IP address to determine whether the tunnel packet to be forwarded can be sent to
Purpose equipment.
If node device determines do not have the IP address of purpose equipment to match with internal layer P address in route table items, node device
It can determine itself and be not establish direct connection relationship with the purpose equipment, so that node device can not also help the commission section
Point device forwards the tunnel packet to be forwarded.Therefore, in view of the situation, node device can continue according to the tunnel to be forwarded
The outer layer purpose IP address of road message carries out routing forwarding to the tunnel packet to be forwarded.
If node device determines have the IP address of purpose equipment to match with internal layer purpose IP address in route table items, node is set
It is standby to determine that itself establishes direct connection relationship with the purpose equipment, so that node device can determine that oneself can be with
The commission node device is helped to forward the tunnel packet to be forwarded.
Internal layer purpose IP address of the node device based on the tunnel packet to be forwarded can be determined pair from route table items
The forwarding port answered.So, node device, which is based on the forwarding port, just can carry out routing forwarding for the tunnel packet to be forwarded.
