Hi! I am trying to configure two Cisco routers MC3810 and 1750-4V to do Voice over Frame Relay. Both the router have the latest IOS. As soon as I enable the vofr cisco command, all my data communications stop. I cannot even ping across. BUT the funny bit is that voice can go through!!! The config on the MC 3810 is : ! interface Serial0 bandwidth 64 no ip address encapsulation frame-relay frame-relay traffic-shaping frame-relay lmi-type ansi ! interface Serial0.1 point-to-point bandwidth 48 ip address 10.1.1.5 255.255.255.252 frame-relay interface-dlci 16 class Voice vofr cisco map-class frame-relay Voice frame-relay voice bandwidth 32000 frame-relay fragment 80 no frame-relay adaptive-shaping frame-relay cir 48000 frame-relay bc 1000 frame-relay be 16000 frame-relay mincir 20000 frame-relay fair-queue The config on the 1750 is: ! interface Serial0 bandwidth 64 no ip address encapsulation frame-relay no ip mroute-cache frame-relay traffic-shaping frame-relay lmi-type ansi ! interface Serial0.1 point-to-point bandwidth 48 ip address 10.1.1.6 255.255.255.252 no ip mroute-cache frame-relay interface-dlci 16 class Voice vofr cisco map-class frame-relay Voice frame-relay cir 48000 frame-relay bc 1000 frame-relay be 16000 frame-relay mincir 20000 no frame-relay adaptive-shaping frame-relay fair-queue frame-relay voice bandwidth 32000 frame-relay fragment 80 Can someone please explain what am I doing wrong and how can I make this work?? Any Help will be appreciated.
