To do… Use the command... Remarks
Modify the IP address of current
node on the explicit path
modify hop ip-address1
ip-address2 [ [ include [ loose |
strict ] | exclude ]
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.
Remove a node from the explicit
path
delete hop ip-address Optional
Display information about the
specified or all nodes on the
explicit path
list hop [ ip-address ] Optional
When establishing an MPLS TE tunnel between areas or Autonomous Systems (ASs), you must use a
loose explicit route, specify the area border router (ABR) or autonomous system boundary router
(ASBR) as the next hop of the route, and ensure that there is a reachable route between the ABRs or
ASBRs. For details about area, AS, ABR, and ASBR, see related documents in the Layer 3 - IP
Routing Configuration Guide .
Configuring MPLS TE tunnel constraints
Follow these steps to configure MPLS TE tunnel constraints:
To do… Use the command... Remarks
Enter system view system-view ––
Enter MPLS TE tunnel interface
view
interface tunnel tunnel-number ––
Specify a path for the tunnel to use
and set the preference of the path
mpls te path { dynamic |
explicit-path pathname }
preference value
Optional
By default, a tunnel uses the
dynamically calculated path.
Submit current tunnel
