Function

The destination command specifies a destination for a GMPLS UNI tunnel.

The undo destination command deletes the destination address of a GMPLS UNI tunnel.

By default, no destination is specified for a GMPLS UNI tunnel.

Usage Guidelines

Usage Scenario

The destination IP address of a GMPLS UNI tunnel is usually the node ID of an egress EN. An ingress EN initiates the creation of a GMPLS UNI tunnel, and adds the destination IP address of the tunnel to the ERO field in a Path message. Then, the ingress EN sends the Path message to the destination (egress EN) hop by hop along the explicit path from the ingress EN to the egress EN. After the egress EN receives the Path message, it replies to the ingress EN with a Resv message. A GMPLS UNI tunnel is then established.

When configuring a forward GMPLS UNI LSP, you need to run the destination command to specify the destination IP address for this LSP. The destination command only needs to be run on an ingress EN.

Prerequisites

The gmpls-tunnel command has been run to establish a GMPLS UNI tunnel.

Precautions

Setting the value of dest_addr to be the node ID of an egress EN is recommended.

Example

# Specify 3.3.3.3 as the destination IP address of the GMPLS UNI tunnel toRt2.

[*HUAWEI-mpls] mpls te
