The destination command specifies the destination IP address of a tunnel interface.
The undo destination command deletes the destination IP address of a tunnel interface.
By default, no destination address is configured.
| Parameter | Description | Value |
|---|---|---|
| vpn-instance vpn-instance-name | Specifies the name of the VPN instance that the destination address of a tunnel belongs to. When the tunnel interface uses GRE, you can specify vpn-instance vpn-instance-name. | The value is the name of an existing VPN instance. |
| dest-ip-address | Specifies the destination IP address of a tunnel interface. | The IPv4 address is in dotted decimal notation. The IPv6 address is a 32-digit hexadecimal number, in the format X:X:X:X:X:X:X:X. |
Usage Scenario
When configuring a GRE, MPLS TE, IPv4 over IPv6 tunnel or manual IPv6 over IPv4 tunnel, create a tunnel interface. After a tunnel interface is created, run the destination command to specify the destination IP address for the tunnel interface.
When using the destination command on a PE to specify the destination address of a GRE tunnel bound for a CE, you need to set vpn-instance vpn-instance-name in the command to specify the name of the VPN instance to which the destination address belongs.
Prerequisites
A tunnel interface has been created using the interface tunnel command, and the encapsulation mode is set to GRE, MPLS TE, IPv4 over IPv6 or IPv6 over IPv4 of manual mode using the tunnel-protocol command.
Precautions
Two tunnel interfaces with the same encapsulation mode, source address, and destination address cannot be configured simultaneously.
You can configure a main interface working in Layer 3 mode as the source tunnel interface.
On the GRE, MPLS TE, IPv4 over IPv6 tunnel or manual IPv6 over IPv4 tunnel, the destination address of the local tunnel interface is the source address of the remote tunnel interface, and the source address of the local tunnel interface is the destination address of the remote tunnel interface.
