It depends on where you configure the "backup interface" command.
If you configure the command in a FR physical interface you have to:
- Pull the cable off
OR
- Change your frame-relay lmi-type
Admin shutdown will not work with a FR physical iterface.
But if you configure the command in a FR subinterface, you can admin
shutdown the physical interface, then the subinterface will go down and the
backup will work.
In this case the "backup interface" command is in a subinterface.
If i'm wrong, please correct me.
