Master vtp configurations by setting up a lab domain, server and client modes, and verifying revisions with http status, while understanding transparent mode resets and vlan propagation.
Learn how spanning tree elects the root bridge via bridge IDs and VLANs, and how root ports and designated ports are chosen by cost, priority, and port IDs.
Learn pvst and rapid spanning tree modes, including per VLAN topologies and distinct port states, compare convergence times and timers, and examine edge port behavior in rapid spanning tree.
Create ether channels that bundle interfaces into one port channel for dual uplinks with no blocking. Use on, lacp, or pagp modes and ensure consistent member configurations.
Stack switches to form a single logical switch with port channels and a single management IP, while a master switch handles control plane and seamless failover.
Configure dhcp snooping to ensure clients only receive dhcp server messages from trusted sources, preventing man-in-the-middle outages. Define trusted ports and vlans; monitor bindings to reject untrusted traffic.
Explore how IPv4 networks use EIGRP to form adjacencies, exchange updates, and compute metrics from bandwidth and delay for decisions. Learn about feasible distance, reported distance, successors, and route redistribution.
Configure EGP autonomous system one across the lab routers, enable and verify peering, advertise networks, and redistribute a default route; then tune delay and use variance for unequal-cost load balancing.
Learn to troubleshoot eigrp for ipv4 by verifying matching autonomous system numbers, common subnets, and k values, using logs and debugs to diagnose adjacency issues.
Restrictions for Implementing EIGRP for IPv6
Explore configuring a PPPoE client and server, including dynamic IP assignment via IPCP, virtual dialer and template interfaces, CHAP authentication, and IP address negotiation on dialer interfaces.
discover how quality of service prioritizes voice traffic through markings like dhcp and cos, classifications such as nbar, and prioritized queuing using cbwfq and llq to prevent tail drop.
Configure an ipv6 access list on a router to permit icmp to r2’s loopback and deny all other traffic inbound on r1’s f10 interface, noting syntax differs from ipv4.
Troubleshoot layer 3 end-to-end connectivity between host A and host B by pinging, checking gateway reachability, interface status, subnet alignment, and static routes with trace route.

Student Feedback
-"I think this course is great, I've been studying for the ICND2 using skillsoft but this course explains some thing different which has been easier for me to grasp"
-"So far I find this to be well explained and cuts down a lot from the book into what you really need to know for the exam and is saving me time. He really knows his stuff for this course and would recommend his to anyone"
