Explore RIP's versions, v1 and v2, as a distance-vector protocol using hop count up to 15, updates every 30 seconds, and mitigations including split horizon, route poisoning, and hold-down timers.

Explore how EIGRP uses the diffusing update algorithm (dual) to provide fast convergence, equal and unequal load balancing, and route summarization, with IPv4 and IPv6 configuration and verification commands.

Learn to optimize EIGRP by limiting query traffic with stub routers, SIA queries, and manual and automatic route summarization, and improve convergence with versatile load balancing.

Explore how EIGRP named mode configures IPv4 and IPv6 under a single router IP instance, using address-family blocks, per-interface settings via AF interface mode, topology-based routing, and verification commands.

Configure eigrp with autonomous system 50, disable auto-summarization, and advertise interfaces and loopbacks 172.30.0.0. Use passive interfaces, summarize 0.0.0.0 to 7.255 as single route, and apply variance 2 toward 10.120.0.0/24.

Explore how OSPF, a link-state IGP, uses Dijkstra and cost metrics for fast convergence, DR/BDR elections, ABRs, and single- or multi-area designs.

Explore multi-area OSPF design, linking areas to backbone via ABR and ASBR to reduce routing overhead, with LSA types, inter-area and external summarization, and v2/v3 configuration.

Explore OSPF optimization through route summarization by ABRs and ASBRs to reduce routing tables, extend the backbone with virtual links, and implement stub, stubby, not-so-stubby areas, and default route origination.

Configures an OSPF network across area zero, area ten, and area twenty, redistributing static routes into OSPF with an E2 metric of 200 and creating router IDs matching device names.

Configure advanced OSPF: redistribute static routes as E1, enable passive interfaces, apply MD5 and clear text authentication, stub areas, and use a virtual link with a default route.

Explore OSPFv3 for IPv6 networks, including multi-area topologies with ABR, IPv6 neighbor verification, and LSA types 8 and 9, plus inter-area prefix and router LSAs, and stop-area configurations.

Learn to use multiple routing protocols for different network needs, with OSPF for internal routing and BGP for external, and understand administrative distance and common values.

Enable seamless connectivity between OSPF and EGP domains by redistributing routes, importing and converting protocols, and assigning a seed metric to external routes (E1 and E2) for proper routing decisions.

Configure igp and ospf with no auto and redistribution, prevent external ospf metric increases, and apply distribute list filter for odd router1 loopbacks plus route-map for /24 routes in igp.

Perform advanced redistribution between IGP and OSPF using route maps and access lists, with seed metrics, to ensure mutual redistribution and prevent unwanted networks entering the OSPF domain.

Activate route filtering using distribute lists, prefix lists, and route maps to control routing updates, then redistribute between IGP, OSPF, and BGP with access lists and route tagging.

Explore Cisco Express Forwarding methods: process switching, fast switching, and topology-based switching with FIB and adjacency tables. Understand performance, scalability, and trade-offs for large networks.

Learn how path control uses policy based routing to steer traffic by source, destination, protocol, and application, enabling load balancing with ip sla driven path selection.

Configure policy-based routing with access lists and route maps to steer PC one to ISP two, and PC two's telnet and https to ISP one, with traffic to ISP two.

Plan enterprise internet connectivity by selecting an ISP and provisioning a physical link. Configure routing and IP addressing, implement edge, link, and ISP redundancy, and understand IANA and regional registries.

Learn how to configure a single home IPv4 internet connection using either a static IP provided by the ISP with a default route, or dynamic IP via DHCP.

Learn how NAT maps private IP space to public addresses—static, dynamic, and PAT—covering inside local, inside global, outside local, and outside global concepts.

Explore IPv6 address assignment using slaac and dhcpv6, including router advertisement options, dns and domain name provisioning, and configuring stateful and relay dhcpv6 on Cisco routers.

Learn the basics of BGP, how it routes between autonomous systems using AS path and next hop, and manage routing tables with open, keepalive, update, and notification messages.

Explore basic BGP configuration, including eBGP and iBGP concepts, direct and loopback peering, multihop, update source, and methods to advertise networks via network or redistribution.

Configure and verify BGP neighbors across different and same autonomous systems by using loopback-based peering, update source loopback, ebgp multihop, and static routes after establishing IGP reachability.

Learn how BGP determines the best path using as-path, next-hop, and origin, then apply optional attributes like local preference, med, and weight to influence route selection.

Control BGP routing updates with prefix lists, as-path filters, and route maps, including locally sourced routes, while using BGP peer groups to simplify configuration.

Configure multiprotocol BGP for IPv6 internet connections, enabling IPv4/IPv6 unicast and multicast routes, with practical router configurations for IPv6 adjacency and network advertisements.

Master advanced BGP configuration with route summarization using aggregate addresses and summary-only. Control route propagation through BGP communities, no export, no advertise, and default originate.

Learn how BGP route reflectors reduce full-mesh sprawl by reflecting best routes to clients while preserving next-hop attributes, and how originator-id and cluster-list prevent routing loops.

Master DMVPN fundamentals, a scalable Cisco VPN with IPsec overlays and on-demand spoke-to-spoke tunnels. See how phases 1–3 optimize hub-and-spoke connectivity with NTP redirects and shortcuts.
