gmpls-tunnel

Function

The gmpls-tunnel command displays the view of an existing GMPLS UNI tunnel or creates a GMPLS UNI tunnel and displays its view.

The undo gmpls-tunnel command deletes a GMPLS UNI tunnel.

By default, GMPLS UNI tunnels are not created.

Usage Guidelines

Usage Scenario

According to the convention, interworking between IP networks and transport networks needs to be configured manually, which is time consuming and increases carriers' service provision and maintenance costs. Generalized Multi-Protocol Label Switching (GMPLS) properly solves the problem. Using GMPLS for interconnection between IP networks and transport networks is recommended because this technology can greatly reduce service operation and maintenance costs.

At present, the device applies the GMPLS technology in the UNI model. The configuration is rather simple. You only need to configure a GMPLS UNI tunnel on the ingress EN and egress EN of IP networks. Then a tunnel will be automatically created across the transport network.

After a GMPLS UNI tunnel is established, the two ends of the tunnel need to be bound to physical interfaces and the IP addresses and routing information of the interfaces need to be advertised to the IP networks. IP services then can be transmitted over the GMPLS UNI tunnel. In real world situations, the interfaces bound to the GMPLS UNI tunnel can be used as common physical interfaces.

Prerequisites

The mpls te command has been run to enable MPLS TE globally.

Follow-up Procedure

Configure tunnel attributes in the GMPLS UNI tunnel view, such as tunnel bandwidth and service authentication.

Example

# Create a GMPLS UNI tunnel named toRt2.

<HUAWEI> system-view
[~HUAWEI] mpls
[*HUAWEI-mpls] mpls te
[*HUAWEI-mpls] quit
[*HUAWEI] gmpls-tunnel toRt2
