Usage guidelines
FTN entries are FIB entries that contain outgoing labels. When an LSR receives an unlabeled packet, it
searches the corresponding FTN entry based on the destination IP address. If a match is found, the LSR
adds the outgoing label in the FTN entry to the packet and forwards the labeled packet.
You can use the mpls-forwarding statistics prefix-list command to enable FTN forwarding statistics only
after the ftn enable command is executed. Otherwise, the device does not collect statistics on FTN
forwarding.
