CCNA: ACL Placement – Std Near Dest, Ext Near Source

Dual-router Branch/HQ lab with a branch client and an HQ server. You will apply an extended IPv4 ACL inbound near the source on the Branch LAN to block specific traffic (TCP/80) while permitting others (ICMP), and a standard IPv4 ACL outbound near the destination on the HQ LAN to admit only the approved source. Validate from real hosts, confirm ACL hitcounts, and keep inter-site connectivity via static routes over a /30 transit.

ACL Logging & Order: Correct Permit/Deny Sequencing

Three-router static-routing lab with two Linux endpoints. An extended IPv4 ACL is intentionally misordered inbound near the source, causing Telnet to be permitted unexpectedly. Learners must observe first-match behavior via hit counters, enable buffered logging to see ACL log entries, and then correct the ACL sequence so Telnet is blocked while SSH and ICMP are permitted. All routers include a complete SSH management plane. The final solution forwards end-to-end and is enterprise-clean.

ACL Wildcard Masks: Match Host, Subnet, and Range

Hands-on CCNA ACL practice using standard ACLs and wildcard masks to allow a single host, a contiguous range, and an entire subnet while proving a deny. You will place the ACL near the destination, order statements correctly, verify with end-host pings and ACL counters, and troubleshoot common mistakes.

CCNA Default Routes: Edge-to-Core Gateway of Last Resort

Configure a default route on a branch edge router and a return static route on an upstream core router to enable full bidirectional connectivity between a stub branch LAN and a core server LAN. Verify the S* default route, gateway of last resort, and end-to-end reachability from real hosts. Troubleshoot missing default or return paths.

CCNA Static Routing: Host vs Subnet (/32 vs /24)

Deploy a compact two-site topology with a WAN core and two end hosts to practice IPv4 static host routes (/32) versus subnet routes (/24). You will configure a specific /32 host route to steer one destination host over the direct R1–R3 path while a broader /24 for the same remote LAN is sent via the R1–R2–R3 core. Validate with show commands and traceroute, then troubleshoot longest-prefix match and return-path issues.

CCNA Static Routes: Manual Summarization

Hands-on CCNA static routing and manual summarization lab using a compact HQ–Branch–Remote topology. You will replace three specific static routes to Branch networks with a single /22 summary at HQ, verify end-to-end host reachability, observe the routing table reduction, and prevent over-aggregation loops by adding a Null0 discard route at Branch. A recommended step has you add the same /22 summary at Remote (replacing its default) to practice summarization on both sides.

CCNA Static Routing: Equal-Cost Load Sharing

Build a small HQ–WAN–Branch triangle with two independent WAN paths. Configure equal-cost static routes on both edge routers so traffic to the opposite site’s LAN installs with two next-hops and is load-shared by CEF. Verify end-to-end reachability from real hosts, observe per-flow load sharing on the routers, and compare behavior to a floating static of higher administrative distance.

CCNA Static Routing: 3-Router Full-Mesh

Design and implement a 3-router full-mesh with two edge LANs using static IPv4 routes only. Edges use primary defaults toward the core plus floating (higher AD) backup defaults; the core uses specific routes for the edge LANs. Validate bidirectional reachability, path choice, and failover behaviors from real hosts.

CCNA Static Routing: Floating Static Route as Backup Path

Deploy primary static routes between two branch LANs via a hub router and add a higher-AD floating static for a direct inter-branch backup. Verify end-to-end reachability, simulate a hub outage to trigger automatic failover, then restore the primary path. Includes realistic addressing, unique /30 transits, and host-based verification.

CCNA Static Routing: Troubleshooting Broken Static Routes

Hands-on CCNA static routing troubleshooting in a realistic three-router core/edge topology with two user LANs. Static routing on the network was recently changed and users at SITE-A (10.10.10.10) and SITE-B (10.30.30.10) can no longer reach each other; you will investigate the routers' route tables and next-hop reachability to diagnose and restore full bidirectional connectivity.

CCNA IPv6 Static & Default Routing End-to-End Practice

Hands-on IPv6 static and default routing across a 3-router, 2-LAN topology with end-user hosts. You will enable IPv6 unicast routing, apply IPv6 addressing, configure hub-and-spoke static and default routes, and validate bidirectional host reachability. The guide provides scenario context, step-by-step tasks with the why behind each action, and targeted troubleshooting.

CCNA Static Routing: Bidirectional End-to-End Connectivity

Hands-on CCNA static routing lab: build a small hub-and-spoke with two stub routers and a hub router. Configure default routes on the spokes and specific static routes on the hub so two user LANs reach each other end-to-end. Validate from real hosts and practice first-hop and return-path troubleshooting.

CCNA: OSPF Passive Interfaces & Default Origination

Deploy OSPFv2 across a 3-router, 2-LAN branch/core/edge topology. Mark LAN-facing interfaces as passive so they do not send OSPF hellos or form adjacencies. Originate a default route only from the edge router and verify default propagation end-to-end using real client traffic. Includes realistic troubleshooting around missing adjacencies, non-propagating defaults, and unreachable external destinations.
