Sorry - I was trying to clean the configuration of that interface but
he's the full config:
nterface Serial1/0
bandwidth 45000
ip vrf forwarding 54
ip address 54.1.1.6 255.255.255.0
encapsulation frame-relay
serial restart-delay 0
clockrate 252000
no dce-terminal-timing-enable
no fair-queue
frame-relay traffic-shaping
frame-relay map ip 54.1.1.254 101 broadcast
frame-relay interface-dlci 101
class SE10
no frame-relay inverse-arp
end
