Configuring Traffic Forwarding - 3Com S7906E Configuration Manual

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:
To do...
Enter system view
Enter MPLS TE tunnel interface
view
Configure maximum number of
tunnel setup retries
Configure the tunnel setup retry
interval
Submit current tunnel
configuration
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...
Enter system view
Enter MPLS TE tunnel interface
view
Assign priorities to the tunnel
Submit current tunnel
configuration
