When inserting nodes to an explicit path or modifying nodes on it, you may configure the include
keyword to have the established LSP traverse the specified nodes or the exclude keyword to have the
established LSP bypass the specified nodes.
Follow these steps to configure an MPLS TE explicit path:
To do...
Enter system view
Create an explicit path for
MPLS TE tunneling and enter
its view
Add a node to the explicit path
Specify a next hop IP address
on the explicit path
Modify the IP address of
current node on the explicit
path
Remove a node from the
explicit path
Display information about the
specified or all nodes on the
explicit path
Configuring MPLS TE tunnel constraints
Follow these steps to configure MPLS TE tunnel constraints:
To do...
Enter system view
Enter MPLS TE tunnel interface
view
Specify a path for the tunnel to
use and set the preference of
the path
Submit current tunnel
configuration
Use the command...
system-view
explicit-path path-name
[ disable | enable ]
add hop ip-address1 [ include
[ loose | strict ] | exclude ]
{ after | before } ip-address2
next hop ip-address [ include
[ loose | strict ] | exclude ]
modify hop ip-address1
ip-address2 [ [ include [ loose |
strict ] | exclude ]
delete hop ip-address
list hop [ ip-address ]
Use the command...

Remarks
––
Required
Optional
By default, the include
keyword and the strict keyword
apply. In other words, the
explicit path traverses the
specified node and the next
node is a strict node.
Required
The next hop is a strict node by
default.
Repeat this step to define a
sequential set of the hops that
the explicit path traverses.
Optional
By default, the include
keyword and the strict keyword
apply. In other words, the
explicit path traverses the
specified node and the next
node is a strict node.

By default, a tunnel uses the
dynamically calculated path.
