28.1.2 MFR Configuration

The 4 x T1 MFR bundle between the LR1104A and the Black Box connects two Frame Relay switches, therefore it represents an
NNI interface. The sample configuration defines the 4 x T1 bundle to be of Class C; that is, a minimum of 2 T1 links are required to
be up in order to keep the bundle up. Settings for Bcmin on the MFR bundle are set to correspond with the Class C configuration; that
is, the minimum anticipated bandwidth will be 2 x T1.
