I would like to ask a question, that is, when a packet to the network card, found that the destination MAC is I, is in it, to the network layer, found that the destination IP is not I, do, throw away the package?

CodePudding user response:

Router, the router first check your routing table is the longest match recursive calls are routing routing no drop

CodePudding user response:

Arrived at the network layer, if it is found that the destination IP is not oneself, will query routing table, if there is the IP routing table entries, also from the corresponding interface forwarded, if not the, are discarded

CodePudding user response:

The router did check their own routing table to the destination IP routing, have package forwarding not discarded,
