Ports are manually configured to be in the forwarding state. *** Ports listen and learn before going into the forwarding state. Ports must be blocked before they can be placed in the disabled state. It takes 15 seconds for a port to go from blocking to forwarding Which sequence of commands is used to configure a loopback address on a router?

Two routers have been configured to use EIGRP. Packets are not being forwarded between the two routers. What could be the problem? EIGRP does not support VLSM.

The number of usable addresses assigned to a company is divided into smaller manageable groups. A pool of IP addresses are mapped to one or more MAC addresses.
