The redirect interface tunnel command redirects packets to a specific tunnel. You can apply the action to a specific tunnel based on a traffic behavior, and redirect the traffic with a matching class.
The undo redirect command cancels the configuration.
By default, the tunnel is not configured in the traffic behavior view for the next hop for redirection.
| Parameter | Description | Value |
|---|---|---|
| interface-type |
Specifies the type of an interface. |
The value can only be Tunnel |
| interface-number |
Specifies the number of an interface. |
Specifies the tunnel interface number, in the format of either x or x/y/z.In the format of x, x is an integer ranging from 0 to 4294967295. In the format of x/y/z, the value is an integer ranging from 0 to 31. |
| route-forward |
If specified Tunnel was shut down, the parameter route-forward can be configured to return packets to the original forwarding process. |

Usage Scenario
Traffic can be forwarded to a specified next hop instead of being forwarded based on the route on a network. If this case occurs, redirection must be deployed on the network.
When users transmit P2MP services, traffic must be redirected to an P2MP/TE tunnel. If policy and route-forward are configured and the tunnel(RSVP-TE/SR-MPLS TE) is Down, packets are forwarded based on the FIB entry information obtained through the destination IP address of the packets.<HUAWEI> system-view [~HUAWEI] mpls [*HUAWEI-mpls] mpls te [*HUAWEI-mpls] quit [*HUAWEI] interface Tunnel 10 [*HUAWEI-Tunnel10] tunnel-protocol mpls te [*HUAWEI-Tunnel10] quit [*HUAWEI] traffic behavior b1 [*HUAWEI-behavior-b1] redirect interface tunnel 10
