I'm doing some pre-setup in anticipation for a new multilink frame relay install. Based on a sample config from my ISP and reference from other sources I was trying to create the multi link inerface by using the following command:
Router(config)# interface mfr0
Unfortunately, it doesn't seem to accept mfr. "Unrecognized command".
I've got a Cisco 2621 running IOS 12.3(19). My WIC card is a Cisco, VWIC 2MFT-T1
