Hi, i m getting the below error while i am not getting the ldp session established for the particular device to their peers..


Jan 31 2013 20:29:29-05:13 BAP1 %%01LDP/4/SSNHOLDTMREXP(l)[22]:Sessions were deleted because the session hold timer expired and the notification of the expiry was sent to the peer 3.3.3.3.

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

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


Thanks

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.
