1. check physical interfaces - should be up

2. check if  undo mpls, undo mpls ldp, or undo mpls ldp remote peer commands are running under interface/system view

3. check the routing table/connectivity

4. check the timers, maybe use default values

5. check the version of the switch if support mpls or not

yes, even after enabling; i am not able to find isis route build up which leads to ldp peer formation,

[sw1]display ip routing-table

Route Flags: R - relay, D - download to fib
Routing Tables: Public
         Destinations : 7        Routes : 7

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface  Direct  0    0           D       LoopBack0   Direct  0    0           D       InLoopBack0  Direct  0    0           D       InLoopBack0  Direct  0    0           D    Vlanif10  Direct  0    0           D       Vlanif10  Direct  0    0           D    Vlanif11  Direct  0    0           D       Vlanif11

hi please check isis configuration, looks like there are no isis routes in routing table - no connectivity

I've configured in eNSP exactly your scenario, like in word file, whitout  isis ldp-sync and ldp sessions established.

Yeah, thats fine..its working

want to clarify a thing , is there a way that we hard code the os of 5700 in ensp& make it work for all the supported cmd's in

for !Software Version V200R002C00

i.e by modifying the flash.dat file in C:\Program Files\eNSP\simserver\Devices\LSW\s5700

Maybe eNSP developers can answer to your last question; but you should open a new thread for eNSP :)

I'm glad we clarified with LDP.
