Question 9: 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. resource class affinity
B. IP address
C. MPLS label
D. tunnel endpoint
Correct Answer: B
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
