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. The path setup preference is for lower (not higher)
numbers, so option 1 is preferred.
If you specify the dynamic keyword, the software checks both the physical bandwidth of the interface
and the available TE bandwidth to be sure that the requested amount of bandwidth does not exceed the
physical bandwidth of any link. To oversubscribe links, you must specify the explicit keyword. If you
use the explicit keyword, the software checks only how much bandwidth is available on the link for TE;
the amount of bandwidth that you configure is not limited to how much physical bandwidth is available
on the link.
This command requires the MPLS Services license.
Examples This example shows how to configure the tunnel to use a named TE explicit path and if that path is not
available, then to fall back to a path dynamically calculated from the TE topology database:
switch# configure terminal
switch(config)# interface tunnel-te 1
switch(config-if-te)# path-option 10 explicit name Link5
switch(config-if-te)# path-option dynamic 20
switch(config-if-te)#
