sorry
I meant "it is NOT possible to include frame-relay
intf-dce WITHOUT the frame-relay switching command on
the interface". the interface won't take the dce
command until you enable frame-relay switching.
you will get an error if you try to input the dce
command.i have included the output below:
-------------------------------------------------------
R5(config)#int s2
R5(config-if)#encapsulation frame
R5(config-if)#frame-relay intf-type dce
Must enable frame-relay switching to configure DCE/NNI
R5(config-if)#
------------------------------------------------------
Yes it is possible to include frame-relay
interface-dlci on the interface with frame-relay
switching in the global config.
And you don't need to enable frame-relay switching for
back-to-back frame relay to work.
the no-keepalive command under the interface is
sufficient alongwith other commands i mentioned below.
