Configuring tunnel setup retry 
You may configure the system to attempt setting up a tunnel multiple times until it is established 
successfully or until the number of attempts reaches the upper limit.  
Follow these steps to configure tunnel setup retry:

Assigning priorities to a tunnel  
Two priorities, setup priority and holding priority, are assigned to paths for MPLS TE to make 
preemption decision. For a new path to preempt an existing path, the setup priority of the new path must 
be greater than the holding priority of the existing path.  
To avoid flapping caused by improper preemptions between CR-LSPs, the setup priority of a CR-LSP 
should not be set higher than its holding priority. 
Follow these steps to assign priorities to a tunnel: 
To do… 
Use the command...
