Anyone looked into how to make MPLS-Linux support "IPv4 Explicit NULL 
Label".  That is having a LER pop all the labels and then route based on 
the IP header.  The requirement is to have a dummy0 interface be the 
source/destination within the LER, ergo a ping packet between the 
connect LERs dummy0 interfaces would be labeled.  I can get the labels 
inserted on the outgoing packets but can't seem the find the correct 
configuration to have all the labels popped at the destination LER.

Typcial configuration is:

Host(ping)<-->LER<------(ping with label)----->LER<---->(ping)Host

Desired configuration:

LER(dummy0)(ping with label)<----------->ping with label)(dummy0)LER

Any idea....thanks
