If packet is too large and DF bit is not set, the router will fragment the packet if needed. If DF bit is set, the router must not fragment and therefore will notify with ICMP fragmentation needed because it cannot be forwarded without fragmentation or reducement in size. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
