Vol II task 1.6 Cell Mode MPLS

Hi all

Have problems with cell mode mpls between R9<>CellModeATM<>R1.

R9 loop0 is reachable only from R1.

The LFIB on R9 is empty. 

below are output of some show commands on CellModeATM.

I am using dynamips/gns3 with iewb netfiles.

CellModeATM#sh mpls atm-ldp bindings
 Destination: 131.1.1.1/32
    Headend Router ATM1/0.1 (hop count unknown) -/-  BindWait, CoS=available

  • I am sorry to do this - but I cannot understand which lab you are speaking of

    please re-post under correct forum thread (let's say CCIE SP v1.0 Vol II Lab ??)

    or you could re-post under dynamips section if you suspect it's the culprit - but please state which lab you are referring...

    The CellModeATM router should be configured
    for TDP and not LDP. Post its config and the "show mpls forwarding" output
    from R1 and R9.

  • i was doing this lab today.. it should work,but after completing ospf and mpls sections.

    so finally u should use tdp on interfaces and enable mpls..then advertise it in ospf.. all should work fine.
