HI all

I have one question ?

LAN ---R1 - - R2 - - R3 - - R4 - - R5 ---> R6

On , R1 , R2 , R3 , R4 , R5 are enabled mpls
configured loopback interface with /32 ip , ospf running without problems , mpls also configured using loopback ip .
l2mtu configured where needed , mpls configured on 2000 .

So problem is that from LAN i can ping any ip address expect ips on R6
Ip on R6 that belong for link between R5 and R6 can be pinged but ips from R6 to other routers for customers can not be pinged.
Let say that on R6 is connected R7 and R8 without mpls , so just ip lookup is performed , and those ip can not be pinged ,as if i put
ip's on lan port R7 and R8 , those ips also can not be pinged.

When i turn off mpls on last mpls router R5 , ping go without problem .
So R5 is last mpls router , R6 performing just ip lookup in routing table .

Please help , becuse this is not happening on cisco .

Regards
