[j-nsp] Martini tunnel issue with logical router

[Muhammad Aamir]

Hi,



I am facing L2VPN Martini tunnel issue. In my environment Martini tunnel
shows UP but CEs are not able to communicate end-to-end. I have configured
all PE and P router on logical routers and CE are configured on physical
routers. Following is connectivity



CE1 ==> PE1 ==> P ==> PE2 ==> CE2



Martini works fine if I connect CE2 to P router directly but while
connecting CE2 with PE2, CEs are not communicating end-to-end. I have also
changed MTU size of logical tunnel interface due to dual label appends but
no success. Though same config and topology works fine with physical
routers.



Any one came across same issue L2VPN with logical router. Any hint?

Following is configuartion and output.
