If one of the host connected to Sw-AC3 wants to send message to ip 190.0.2.5 (or any ip on a different subnet) what will be the destination MAC address ?

Correct Answer: and Explanation: Because the destination address is on a different subnet from the switch, the packet will be forwarded to its default gateway To verify the default gateway of this switch, use the show running-config command From the output above, we can see that its default-gateway is 1921681254 Which can be said to be a layer 3 device (router); in this case, the VLAN-R1 router You can use the show cdp neighbor detail command verify further From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 1921681254)The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3 To verify the MAC address associated this interface is interface, you use the show mac-address-table command: Looking closely at the table above, you will discorver that the corresponding MAC address is 000ab7e98360 Although there are some entries on port Fa0/3 with different Vlans ,but they have the same MAC address From the output above, you can confirm that the switch's default gateway is VLAN-R1 router (with the IP address of 1921681254)The interface FastEthernet0/3 shows that the switch is directly connected to VLAN-R1 router through the switchport Fa0/3 To verify the MAC address associated this interface is interface, you use the show mac-address-table command
