[c-nsp] IOS-XR - ICMP inside MPLS between LOOPBACKs int

[Michal Grzybczyk ( GMAIL )]

Hi,

I have interesting behavior when I test my MPLS configuration
on ASR 9000.
Cisco IOS XR Software, Version 4.2.0[Default]

I tried to ping between ASRs inside VRF, creating some Loopback interfaces
simulating CE side and it failed. I was workng on it some days, 
configurations
looks good and nothing.
Some inspiration push me to create it on physical interface and it works !


Do you know any trick to solve or it is bug in software or it is normal 
on ASR
and this will never change ?


Best Ragards,
