If you use Strata DU-Annex in Stratacom MGX Frame-Relay Switches (for
example)
, you must use "ansi" LMI at the router. Try to debug with: debug
frame-relay lmi.
Last time i used 2611 with IOS 12.0(7)T connected to MGX but it seems that
LMI autosense doesnt work at all, need to put the frame-relay lmi statement
clearly
in interface configuration.
Cheers,
Carlos
