: Disable all unused ports with the shutdown command and move them to a "Black Hole" VLAN (e.g., VLAN 999). 4. Configure DHCP and Wireless Enable automatic addressing and wireless connectivity.
: Restricts access on edge interfaces by pinning authorized MAC structures down to an exact, sticky count.
All required objectives were met: ✅ VLANs configured and trunking operational ✅ Inter-VLAN routing verified ✅ OSPF and static routes functional ✅ DHCP providing IPs to end devices ✅ NAT overload working for internet-bound traffic ✅ SSH secured with ACL ccna-2v7.0 case study -rev b-

static routing until a permanent dynamic routing solution is decided. Core Phases of the Revision B Case Study R1(config)# ip route 0
Virtual LANs (VLANs) are used to segment a physical network into smaller, isolated broadcast domains. You will be tasked with creating multiple VLANs, assigning switch ports to them, and configuring between switches to carry traffic from multiple VLANs across a single link.
: 172.25.64.0 /23 yielding 512 total addresses.
A core component of Rev B is optimizing a given IPv4 block (such as 192.168.10.0 /24 or a private Class B block) using Variable Length Subnet Masking (VLSM). You must allocate subnets based on host requirements, typically arranged from largest to smallest: Subnet/VLAN Name Host Requirement Subnet Mask (CIDR) /26 General corporate users VLAN 20 - Engineering /27 High-bandwidth users VLAN 30 - Management /28 Network administrators VLAN 99 - Native /28 or /29 Untagged trunk traffic Point-to-Point WAN /30 Router-to-Router links 2. Switching & Layer 2 Infrastructure : Restricts access on edge interfaces by pinning
: Configured on all access ports to allow rapid client transitions while preventing rogue switches from introducing spanning-tree loops.
Maybe the user is referring to a specific case study that might be available on GitHub. I'll search for "ccna-2v7.0-case-study" on GitHub. 8 might be relevant. Let's open it. is a student project, not a case study.
One of the most time-consuming parts of the Rev B case study is configuring DHCP for all VLANs. The case study usually prohibits using a separate server; R1 or R2 must act as the DHCP server.
It’s a critical exercise for anyone preparing for the new CCNA 200-301 exam. It moves beyond individual chapter labs and forces you to integrate skills like: 🔹 Subnetting and Addressing Schemes. 🔹 VLAN & Trunk configuration. 🔹 Inter-VLAN Routing (Router-on-a-Stick or L3 Switching). 🔹 DHCP & DNS services. 🔹 Security (Port Security, SSH, ACLs).
