ONFIGURATION

As a prerequisite to perform this command, the current physical interface must be 
configured as a MFR bundle link, using the

 command.

After the above configuration, execute the 

 command in all views to 

display the running of the MFR configuration, and to verify the effect of the 
configuration.

Execute the 

 command in user view for the debugging of MFR.

Router A and Router B are directly connected via Serial4/0/0 and Serial4/0/1. The 
frame relay protocol is used to bundle the two serial ports for broader bandwidth.
