Apply these foundational commands to the , PhoenixSW-1 , BangorRouter , and BorderRouter .
The primary goal of Revision B is to validate your ability to integrate the core technologies introduced in CCNA v7.0 . Key objectives include:
PHX-SW-1(config)# ip domain-name cisco.com PHX-SW-1(config)# crypto key generate rsa The name for the keys will be: PHX-SW-1.cisco.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. How many bits in the modulus [512]: 1024 PHX-SW-1(config)# ip ssh version 2 PHX-SW-1(config)# username guest privilege 15 secret cisco PHX-SW-1(config)# line vty 0 4 PHX-SW-1(config-line)# login local PHX-SW-1(config-line)# transport input ssh PHX-SW-1(config-line)# logging synchronous PHX-SW-1(config-line)# exit Use code with caution. Phase III: Layer 2 Optimization and Trunking

One of the first and most crucial tasks is designing an efficient and scalable IP addressing scheme. The case study typically requires you to use a private IP address range, such as or 192.168.0.0/16 , and to implement Variable Length Subnet Masking (VLSM) to minimize wasted address space.
After successful inter-VLAN configuration, all devices in different VLANs should be able to communicate with one another through the Layer 3 gateway.
Two essential services that almost every modern network relies on are and NAT (Network Address Translation) . The ccna-2v7.0 case study -rev b- almost always includes tasks for configuring both. Apply these foundational commands to the , PhoenixSW-1
For , case studies may require SLAAC with Stateless DHCPv6 , combining router-advertised prefixes with DHCPv6 for additional parameters like DNS server addresses.
With the subnets defined, you must configure the switching fabric to segment traffic using 802.1Q encapsulation. 1. VLAN Creation and Port Assignment Configure all access switches to host the end devices.

Revision B places heavy emphasis on securing infrastructure devices from unauthorized access. 1. Basic Switch and Router Hardening
The project is divided into phases that require the configuration of routers, Layer-3 switches, and end devices across the following domains: IP Addressing & VLANs:
