Figure VPN-3-1Encapsulated tunnel message format

For example: The format of IPX transmission message encapsulated in IP Tunnel is as follows:

IP GRE IPX

Passager Protocol

Carrier Protocol or

Encapsulation Protocol

Transport Protocol

Figure VPN-3-2Format of transmission message in the tunnel.

II. Applicable range

GRE can fulfill the following several services:

1)Multi-protocol local network transmits via single-protocol backbone network.

Novell IPX

Protocol

Group1

INTERNET

Novell IPX

Protocol

Group2

IP protocol

Term 1

RouterA

Tunnel

RouterB

B

IP protocol

Term 2

Figure VPN-3-3Multi-protocol local network transmits via single-protocol backbone network

In the above figure, Group1 and Group2 are the local networks running Novell IPX protocol. Term1 and Term2 is the local network running IP protocol. The tunnel encapsulated with GRE protocol is adopted between Router A and Router B. Thus Group1and Group2 can communicate without affecting each other, so are Term1 and Term2.

2)Enlarge the operating range of the hop-limited network (e.g. IPX).
