Solved: Frame Relay switching - DCE LMI down

Randyx · ‎02-18-2014

Hi Guys,

I'm trying to setup frame-relay switching. I was having trouble with the connection. I have 2 2691 and 1 2621 router. I set up 1 2691 as the Frame-Relay swith and to other 2 as remote devices. I was practicing the multi-point frame relay. I was able to make the 2 2691 routers communicate but not able to make the 2621 communicate with the remote device. see logs below:

I think I already checked everthing but the connection from 2691 to 2621 doesn't seems to work. I already tried interchaning the router connection but the 2621 is always the one that does not work. Please assist. Thanks in advance.

Hi,

Did you set the LMI type on the interface ? It seems it is different from the switch.

Hi,

Could you post sh run int on the 2621 as well as sh frame map and sh frame pvc | in DLCI

Hi Alain,

Below is the result of sh int and the sh frame map..there was no output though for sh frame pvc | in dlci
