A server which provides a GRE tunnel function, comprising:
- a selecting means to select any one of a layer 3 transferring method and a layer 2 transferring method, which designates a direct interface to carry out transferring, as a transferring method in the case that GRE tunnel encapsulation is carried out, and to select said layer 2 transferring method if both said transferring methods are available.
A GRE tunnel encapsulation transferring method which is used in a server providing a GRE tunnel function, comprising:
- selecting any one of a layer 3 transferring method and a layer 2 transferring method, which designates a direct interface to carry out transferring, as a transferring method in the case that GRE tunnel encapsulation is carried out;
- and
- selecting said layer 2 transferring method if both said transferring methods are available.
A program storing medium storing a program which makes a computer as a server, which provides a GRE tunnel OSPF function, carry out a selecting processing of selecting any one of a layer 3 transferring method and a layer 2 transferring method, which designates a direct interface to carry out transferring, as a transferring method in the case that GRE tunnel encapsulation is carried out, and selecting said layer 2 transferring method if both said transferring methods are available.
