When using the tunnel mpls traffic-eng path-option 1 explicit name test command in Cisco MPLS TE tunnel configurations, the test explicit-path configuration will consist of a list of which values?
A. tunnel endpoint
B. resource class affinity
C. MPLS label
D. IP address
Correct Answer: D
Explanation/Reference:
Explanation:
tunnel mpls traffic-eng path-option
To configure a path option for a Multiprotocol Label Switching (MPLS) traffic engineering tunnel, use the tunnel mpls traffic-eng path-option command in interface configuration mode. To disable the specified path option, use the no form of this command.
tunnel mpls traffic-eng path-option number {dynamic | explicit {name path-name | path-number}} [lockdown]
no tunnel mpls traffic-eng path-option number {dynamic | explicit {name path-name | path-number}} [lockdown]
Syntax Description number = When multiple path options are configured, lower numbered options are preferred.
dynamic = Path of the LSP is dynamically calculated.
explicit = Path of the LSP is an IP explicit path.
name path-name = Path name of the IP explicit path that the tunnel uses with this option. path-number = Path number of the IP explicit path that the tunnel uses with this option.
lockdown = (Optional) The LSP cannot be reoptimized.
Usage Guidelines
You can configure multiple path options for a single tunnel. For example, there can be several explicit path options and a dynamic option for one tunnel. Path setup preference is for lower (not higher) numbers, so option 1 is preferred.
Examples
The following example shows how to configure the tunnel to use a named IP explicit path:
Router(config-if)# tunnel mpls traffic-eng path-option 1 explicit name test
