Handling Process

A:
1. The NE40E/80E must be installed with a Tunnel Service Unit (TSU) to support GRE.
2. The NE40E/80E of version V300R001 supports only multicast VPN GRE tunnels but cannot carry out GRE encapsulation for attached service data. The NE40E/80E of version V300R002 can implement general GRE applications.
3. Method for configuring loopback interface
interface LoopBack1/ It is recommended not to use the loopback address of the routing neighborip address 200.0.0.1 255.255.255.255
target-board 2// Here, 2 specifies the slot number of the TSU
binding tunnel gre// Set the tunnel encapsulation protocol to GRE
4. Method for configuring the tunnel

interface Tunnel2/0/0 // The first number 2 specifies the slot number of the TSU
ip address 192.168.1.1 255.255.255.252
source LoopBack1// Bind the tunnel to the loopback interface configured in the previous step
destination 200.1.1.1
