What happens when packets are fragmented at MLP level on 7500?
If the packets are fragmented at the MLP level and if the reassembled packets are greater than MRRU, then packets are dropped on multilink. Transmit-side fragmentation is supported on dMLP only with dLFI. Packets are fragmented at the MLP level only if the packet_size is greater than the frag_size and less than the MRRU. If packets more than the MRRU are sent and if it is not fragmented at the IP level, then the other end drops all the packets size they are not fragmented at the MLP level because the packets are more than MRRU.
