Cisco 300-101 - ROUTE - Implementing Cisco IP Routing

Explore the fundamentals of routing protocols, compare interior and exterior routing, and examine interior routing types such as distance-vector and link-state.

Compare routing protocols across the Cisco enterprise network infrastructure, distinguishing campus, edge, and remote sections, and evaluate static routing and interior gateway protocols like OSPF for scalable, multi-vendor networks.

Contrast interior and exterior routing protocols, including RIP, OSPF, ISIS, EIGRP, and BGP, and note static routes, convergence time, and path attributes.

Explore route summarization and how it improves routing protocol scalability by shrinking routing tables and using OSPF areas to confine issues to smaller sections.

Explore how different network topology types influence the choice of a routing protocol and the model used to run the protocol.

Explore IPv6 address types, including global unicast and link-local addresses, prefixes, 64-bit interface identifiers, multicast, and unique local, loopback, and unspecified addresses.

explore network types, including broadcast ethernet, point-to-point serial, and non-broadcast multi-access frame relay, and address split-horizon, hello packet challenges, plus subinterfaces to create multiple point-to-point virtual circuits.

Learn how routing information travels across the internet, address challenges from multi-hop routers and direct routing protocol adjacencies, and mitigate these issues with VPN connections and NAT considerations.

Identify the challenges technicians face when linking branch offices to the main office. Explore options for connecting sites, including GRV tunnels and the MVP in setups.

Explore options for connecting remote sites to headquarters with MPLS-based VPNs and tunneling, including layer 2 and layer 3 MPLS, GRE, IPsec, DMVPN, and hybrid VPNs.

Explore GRE tunneling and dynamic multipoint VPN for secure, scalable hub-and-spoke routing. Learn how DMVPN uses NHRP to automatically discover spoke addresses and create spoke-to-spoke tunnels with optional IPsec.

Explains how nhrp enables hub-and-spoke dmvpn to dynamically learn spoke addresses, register on boot, and establish tunnels with mapping and adjacency tables, secured by IPsec.

Discover the updated RIP for IPv6, called RIPng, including how to configure it and how it differs from the IPv4 version.

RIP overview explains RIP and RIPng as hop-count protocols, which can yield suboptimal paths. It contrasts IPv4 RIP v2 with RIPng, UDP ports 520 and 521, and IPv6 multicast updates.

Enable ipv6 routing globally, create a named ripng process, and enable it on interfaces using interface commands; optionally announce default routes with default information originate.

Investigate the RIP database with show ip rip on ethernet 2 to view installed and expired routes, while noting 30-second updates and 180-second expiry with next-hop link-local address.

Configure ipv6 routing and set up ripng across three routers, enabling rip on interfaces and verifying with show ipv6 route and a ping test.

Explore the basics of GOP, a Cisco proprietary protocol with the fastest convergence among routing protocols in this module, and preview its advanced features for upcoming lessons.

Explore eigrp features: fast convergence, partial updates, and bandwidth- and delay-based metrics. Configure eigrp by enabling it with a router id, network commands, and optional passive-interface to suppress hellos.

Adjust EIGRP hello and hold timers to improve convergence using ip hello-interval and ip hold-time, verify with show ip EIGRP interfaces detail, and understand frame relay non-broadcast multi-access effects.

Establish eigrp over layer 2 mpls vpn topologies by linking the last customer router to the provider edge, using point-to-point or multipoint-to-multipoint setups with a single broadcast domain.

Demonstrates configuring EIGRP for IPv4 across three routers using AS 100, with network statements for 192.168.6.0 and 192.168.5.0, verifying learned routes with show ip route and successful pings.

Explore how Elijah Arpey builds a typology database by aggregating information from other routers and placing it into the typology database to enhance GOP understanding.

Explore the topology table, neighbor table, and routing table in the dual algorithm for best path selection. Assess advertised distance, feasible distance, feasibility condition, and feasible successor for fast convergence.

Learn how EIGRP exchanges routing information, advertises prefixes from direct, static, and redistributed routes, and calculates a composite metric using bandwidth and delay with optional K values.

Apply the feasibility condition to identify a feasible successor by ensuring the feasible distance is lower than the advertised distance of the current successful route, as shown with two paths.

Explore fast routing convergence by selecting a feasible successful route or second best route for the typology table, and examine how GOP features enable convergence when no feasible successor exists.

Examine how EIGRP queries find alternate routes when no feasible successor exists and how stub routers reduce query overhead with connected, summary, static, redistribute, and receive only options.

Explore why stuck in active states disrupt Cisco routing, how the query process leads to cascading neighbor resets, and how extra verification messages prevent failures.

Use summary routes to reduce query scope and improve convergence, stopping queries across routers; learn about automatic summarization on older IOS versions and how to disable it with no auto-summary.

Configure EIGRP load balancing across equal-metric paths, automatically using up to four routes (sixteen with maximum routes). Use variance to balance across unequal metrics while ensuring a feasible successor.

Shrink the routing table by applying route summarization on router b, then verify the single summary with show ip route and demonstrate the EIGRP stub feature.

Explore how routing protocol RIP evolved to support IPv6 and compare its IPv6 configuration with IPv4 setup, noting key differences.

Explore EIGRP for IPv6 overview, showing how routers use link-local addresses to form neighbor adjacencies, with multicast, router IDs, metrics, successors, and feasible successors.

Enable ipv6 unicast routing and start an ipv6 eigrp process with autonomous system number, set router-id, and enable interfaces. View neighbors and topology, and review routes with link-local addresses.

Identify matching bits across IPv6 prefixes and convert the first nonmatching field into binary to form a manual summary with a /61 prefix, following the IPv4 approach.

Explore the complexity of configuring AIG R.P. to support both protocols, and learn how Cisco's named AIG GOP enables dual-protocol configuration.

Learn how named configuration for EIGRP unifies IPv4 and IPv6 routing in one place using address families for IPv4 unicast, IPv4 multicast, IPv6 unicast, and IPv6 multicast.

Configure a named virtual instance, enter IPv4 and IPv6 address families, enable interfaces, apply manual summarization, and set up passive interfaces to control neighbor advertisements.

Master the named EIGRP configuration modes, including global, address family, and address family topology configuration, using network statements, summary addresses, passive interfaces, hello and hold time, and redistribution commands.
