Assume
computer A is in subnet A
computer B is in subnet B
two routers are beteen A and B
Computer A send packet to B
the packet must throught a router A then router B then computer B recieve
Computer A must
1.know the router A IP first
2.then use ARP to get the MAC of router A
3.then start to send the packet(router A's MAC and computer B's IP as destination) to B.
4. ............
The problem is how the computer A know the router A's IP(1st step)?
Apart from DHCP/RARP/BOOTP and static routing table?
Thanks!
