Classful vs Classless Routing v1.10 – Aaron Balchunas 1 - Classful vs. Classless Routing Classful vs Classless routing protocols Classful routing protocols do not send subnet mask information with their routing updates. A router running a classful routing protocol will react in one of two ways when receiving a route: • If the router has a directly connected interface belonging to the same major network‚ it will apply the same subnet mask as that interface. • If the router does not have any

NT1330 Unit 2 homework. Assignment 1: DHCP Troubleshooting. Check the workstations using ipconfig /all and find out if the ip range is within the address range you assigned‚ if it is a different address then the workstation failed to contact the DHCP server and has gone into apipa mode. The Network Interface Card might be assigned an incorrect driver. Another possible cause of the problem is that the patch cable is not plugged into the Network Interface Card‚ or is not connected to a switch on
