[ns] How can I setup a backup path for MPLS Network

[Dan Wang]

Hello:

I want to set up a backup path for each active path
in MPLS network. What I need is that when there is
a link failure in the network, the packets automatic
switch to the backup one.

I use make-explicit-route but it will change only if
I explicitly tell it to install the path (by using
flow-erlsp-install).

Is there any way to do it?

Thanks in advance.

Dan.
