Hi all,

I am currently investigating the correlation between TE interface tunnel to
its underlying interfaces.
I would appreciate your input on:

1)Would it be right to say (lets take Cisco tunnel interfaces):
Interface tunnel out-label is determined by the out-label assigned to the
FEC of the destination IP in the tunnel?
2) the actual out-int for traffic going to the tunnel is the physical
int-out assigned to the destination IP FEC of the tunnel?

also, can someone demonstrate in an example?

Thanks,

Yaron
