The New CCNA Exam v1.0 (200-301) By Hexa CCIE Khawar Butt

Explore ip address classes a, b, c for unicast, and class d for multicast. Learn subnet masks (/8, /16, /24), how networks and hosts are allocated, and the loopback concept.

Explore class B subnetting by borrowing bits to create 30, 40, and 80 subnets, determine increments and masks, and calculate networks, hosts, and broadcast addresses.

Explore the OSI seven-layer reference model and the TCP/IP four-layer implementation, mapping functions, headers, and segmentation to enable interoperable networking between vendors.

Explore the router anatomy and boot sequence, including ROM, RAM, flash, NVRAM, and IOS. Understand startup and running configs, console and VTY access, and interfaces such as Ethernet and serial.

Configure router settings by assigning hostnames and domain names to create fully qualified domain names. Set time zone, date, and clock in privileged mode to ensure accurate timestamps across devices.

Configure the router’s three banners—message of the day, login, and exec—using banner motd, banner login, and banner exec commands, with example messages and a change log reminder.

Understand how the running config resides in RAM and how to save it to the startup-config file using copy running-config startup-config or wr, with verification.

secure router console access by configuring a console password or login local with a local user database, protect privileged mode with enable secret, and enable motd banners and logging synchronous.

Configure and verify a point-to-point HDLC serial link between two routers from scratch, assign IP addresses, verify encapsulation, and test connectivity with ping and show interface commands.

Configure PPP multilink to combine two serial links into a single logical interface for higher bandwidth and redundancy; create the multi-link interface and verify with show commands.

Configure ssh for secure remote management by defining a domain name, generating an rsa 1024 key, enabling vty transport ssh, and enforcing username and password authentication.

Learn routing basics: how routing tables are formed from directly connected networks, static and default routes, and dynamic routing protocols, and how admin distance and metrics choose the best path.

Explore distance vector routing protocols, which limit to the next hop and use hops or bandwidth to set routes, with examples like RIP and HRP.

Explore how the link-state routing protocol provides a topology view by having routers advertise their links and costs, and compare it with distance-vector protocols using OSB and ISIS as examples.

Configure static routes to manually direct traffic between three routers, learning the syntax and implementation. See how static routes offer control and low overhead but lack dynamic failover.

Discover how OSPF uses link-state routing, router IDs, areas, DR/BDR elections on multi-access segments, and LSA types 1 and 2 to build a complete topology.

Explore how ospf uses a backbone area zero, area borders, and lsa types to connect multiple areas, and learn about abrs, route summarization, and redistribution.

Configure a multi-area OSPF network by assigning router IDs, advertising loopback networks, and implementing area zero backbone with area ten and area twenty, using point-to-point links and area border routers.

Learn VRRP, the open standard for router redundancy, featuring master and backup roles, a shared virtual IP and MAC, preemption, and failover.

Explore IPv6 address assignment using SLAAC, deriving the host portion from the MAC address with FF FE insertion and the seven-bit inversion, plus network addressing examples.

Configure IPv6 static routes to connect three routers, enable ipv6 unicast routing, and use IPv6 route commands to define destination networks and next hops, achieving end-to-end reachability.

Learn how to replace static ipv6 routes with a default route (::/0) that forwards unknown destinations to the ISP, simplifying edge router configurations and defining the next hop.

Explore how vlan trunking protocol centralizes vlan creation on a vtp server and propagates it to vtp clients across the network, while ports are still configured locally.

discover how spanning-tree protocol prevents loops by electing a root switch, blocking redundant links, and using bpdu to learn topology, including rapid variants and per-vlan instances.

Explore how STP PortFast lets designated switch ports skip listening and learning to forward immediately, reducing startup delay and preventing loop risk when ports connect to end devices.

Configure a two-switch lab with a trunk, assign VLANs 10 and 20, enable portfast and BPDU guard, and verify immediate loop protection and connectivity.

Configure an etherchannel using lacp with active or passive modes to create dynamic port-channel links, then test layer 2 trunks and layer 3 svis with ip routing.

See how DHCP automates IP allocation with pools, exclusions, and leases, use relay agents for centralized servers, and apply the discover, offer, request, and acknowledge flow for default gateways.

Configure the NDP server and clients on Cisco routers to synchronize time across Dubai, Singapore, and New York, ensuring logs and certificate validity.
