How would the ifMTU be used in gmpls-routing-01.txt

[Ling Li <lli@axiowave.com>]

The draft mentioned the following:
  For Packet-Switch Capable interfaces the additional information
  includes Maximum LSP Bandwidth, Minimum LSP Bandwidth, and interface
  MTU
It explained how the Maximum LSP Bandwidth and Minimum LSP Bandwidth are 
expected to use when setting up an LSP. However it says only the following 
on MTU:
   The Interface MTU is the maximum size of a packet that can be
   transmitted on this interface without being fragmented

My question is how the if mtu is expected to use. Would it be used as a 
constraint during LSP setup just like the bandwidth constraint? If this is
the case, would the application/customer ask for a LSP MTU constraint larger
than a specific value or smaller than a value or both? 

Thanks,
