Hello all,
During a static routing practice lab, a student defined his workstation's Default Gateway to the router's Serial Interface and not to the usual Ethernet Interface.
His workstation was physically connected to the R3 LAN and was logically part of network 129.16.0.0
R1---------R2---------R3 | LAN
The link between R3 and R2 was configured using network 1.0.0.0
Instead of defining his workstation's Default Gateway to 129.16.0.1 (R3's FA0/0), he used 1.255.255.254 (R3's S0/0) and everything worked correctly. Is this because of his station's ARP request? The request surely reached FA0/0 because directly connected and seems to have been switched by the router to the Serial Port but I would have imagined that the Gateway had to be defined as a member of the same logical network.
Many thanks
