ASR1K 5xE1 MFR Frame relay traffic not forwarding in one direction

 

 Dear Techies, 

 Hope all is well !

Im doing this inter-op testing with Alcatel device for frame-relay and MFRs and got stuck at this situation which is actually mind boggling and I think i might be missing something "silly" :-(

Its a simple setup of

 

1. My ASR 1002-X with a LAN (Gig0/0/0) port is connected to a traffic generator.(ixia).

2. ASR WAN port is a 5xE1 bundled into a MFR circuit.

3. WAN link goes to a Alcatel box giving me my FR-DCE with E1s over MFR.

Issue is , I can send traffic to max throughput with  flow initiated from  LAN to WAN bit NOT the reverse flow initiated  from WAN side to LAN port. I see traffic coming into my 5xE1s (1.8 mbps each) but the traffic just wont go to the LAN side , somewhere it gets "stuck" or "dropped".

PING works fine from both sides.......but sending traffic is not possible !!
