I have a funny inssue using MPLS VPN (VRF) with Lan (ethernet) in both side of my VRF. look the scene:
CustomerMachines--->Fa0/0.1(Pe1)---MPLS CORE---(Pe2)Fa0/0.2---> CustomerServer
Just one machine each time of lan in Pe1 can ping the server in Pe2, I dont get simultaneous traffic, for example:
If machine 1 in Pe1 is pinging Server in Pe2, just this machine send traffic, if machine2 try to ping I get time out, if I stop machine 1 pinging server, so machine 2 start ping.
Very starnge.. Any idea
