attribute-priority-adaptivity pinned
Configures the secondary tunnel to not move when a better path becomes available.
Syntax: [no] attribute-priority-adaptivity pinned
Description: A secondary tunnel is a tunnel with a non-zero target attribute priority. The attribute-priority-adaptivity attribute determines how a secondary tunnel responds when new network resources become available or when resource parameters change such that "better" paths become available. There are 4 attribute-priority-adaptivity models: disabled, pinned, periodic, and linear.
Pinned attribute-priority-adaptivity means that the secondary tunnel is never re-routed when new network resources become available or other changes make an alternate path more preferable. Nor will the secondary tunnel move if the traffic engineering data base indicates the path no longer meets restrictions such as administrative color or available bandwidth.
If the current path becomes invalid, and attribute-priority-adaptivity pinned is specified, the path will not move. If the current path becomes invalid, and attribute-priority-adaptivity disabled is specified, the path will move.
The secondary tunnel may be moved if it is torn down by an intermediate node RSVP signaling and new network resources or better paths are available. Whether a secondary tunnel is rerouted in this case is determined by the resilience attribute of the secondary tunnel.
Use the attribute-priority-adaptivity pinned command to configure the secondary tunnel, default secondary tunnel or parameter-set to not move when new resources become available, or the current path no longer meets constraints.
Use the no attribute-priority-adaptivity command to remove the attribute-priority-adaptivity specification.
Factory Default: Periodic 1200s jitter 240s.
Command Mode: Traffic engineering parameter-set and traffic engineering tunnel-name.
Example 1: In the following example, the attribute-priority-adaptivity pinned command configures the secondary tunnel to never move:
router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#mpls te ospf
router(config-te)#tunnel oc12toBos
router(config-te-tunnel)#attribute-priority- adaptivity pinned
Example 2: In the following example, the no attribute-priority-adaptivity command removes the attribute-priority-adaptivity specification for the oc12toBos tunnel:
router1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#mpls te ospf
router(config-te)#tunnel oc12toBos
router(config-te-tunnel)#no attribute-priority-adaptivity
Related Commands: attribute-priority-adaptivity disabled
attribute-priority-adaptivity linear
attribute-priority-adaptivity periodic
