By default and based on your config below you should be
using A-Class MFR which means if any link is up then the
MFR interface should be up.
I dont have time this morning to lab it up , but just in case
the class can be negoiated without the other end to a class
other than the default issue the following command to
check:
Router# show frame-relay multilink
Bundle: MFR0, state down, class C (threshold 3), no fragmentation
ID: Bundle-Dallas
Serial5/1, state up/up, ID: BL-Dallas-1
Serial5/3, state up/add-sent, ID: BL-Dallas-3
If the class is other than A then this could be your issue. Have a look
at the URL below for details of the different available classes:
