Parameters

tunnel tunnel-number: Specifies a bypass tunnel by the tunnel interface number. The value range for the tunnel-number argument varies by device operating mode. For more information about configuring the device operating mode, see Fundamentals Configuration Guide.The specified bypass tunnel must be established by RSVP, and the protected interface must not be the outgoing interface of a bypass tunnel.

Usage guidelines

The protected interface (where the command is executed) is the outgoing interface of a primary CRLSP. When the outgoing interface is down or a neighbor failure is detected through the BFD or hello mechanism, traffic of the primary CRLSP is switched to the bypass tunnel.

When you use this command, follow these restrictions and guidelines:

• You can specify a maximum of three bypass tunnels for an interface.

• A bypass tunnel can protect a maximum of three interfaces.

Examples

# Configure tunnel interface Tunnel 0 as the bypass tunnel for VLAN-interface 10.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] mpls te fast-reroute bypass-tunnel tunnel 0
