marking connections and packets

RouterOS General

hi, i want to know when i need to mark only packets since i mark always connection and then packets
and what’s the difference between marking first connection and later packet or packet only


and thanks

A connection mark is a mark that is automatically applied to all packets of a connection. You mark the connection on one packet, and all other packets in the same connection will have the same mark.
Packet marks only are applied to one packet, and do not propagate to other packets in the same connection.

Marking connections first and then packet is much less load for CPU

thanks so in the bridge we need to mark only the packets or we need to mark the connection and the packets ?
