You will configure routers, switches, and PCs to support IPv4 connectivity, switch security, and inter VLAN routing. You will then configure the devices with OSPFv2, DHCP, and dynamic and static NAT. Access control lists (ACLs) will be applied for added security. You will test and document the network using common CLI commands throughout the assessment.

There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface. © 2013 Cisco and/or its affiliates. All rights reserved.
