IP Routing Training | EIGRP | OSPF | IS-IS | BGP

Explore ip routing fundamentals: static and dynamic routing, interior and exterior gateway protocols, such as rip, ospf, eigrp and bgp, and algorithms like distance vector, link state, and path vector.

Static routes provide precise control and use less traffic than dynamic protocols, but they can be hard to manage as networks grow and may lack awareness when routes become invalid.

Configure static routes to a null interface to block traffic without cpu load and prevent routing loops; use a null zero interface with summarized networks.

Demonstrate configuring a static null route on router one to prevent a loop with the ISP when routing 172.16.0.0/20 traffic, using ping and traceroute to verify loop blocking.

Configure ipv6 static routes to reach remote subnets and enable ip version six unicast routing, then verify connectivity with ping and tracert.

Explore EIGRP fundamentals, including the dual algorithm for fast converge and pre-calculated loopless redundant routes, and how autonomous systems share metrics and route information.

Configure and verify an EIGRP lab across four routers, using autonomous system number 10, multiple subnets, passive interfaces, and neighbor adjacencies to learn route selection and topology.

Adjust EIGRP failure detection by configuring hello interval and hold time on routers in classic and named modes. Verify changes with show ip interface detail.

Configure EIGRP route summarization on router three's gigabit 0/2 interface to advertise a single 172.16.0.0/16 route to router four, with router three and a null0 entry.

Demonstrates eigrp distribution list filtering in a lab, blocking 10.1.100.0 subnet at input of router two and 10.3.100.0 subnet at output, using standard and prefix access lists.

Configure IPv6 eigrp with autonomous system 100 in classic mode on router1 and named mode on router2. Advertise 2001:db8:0:12 and publish 2001:db8:11 on router1, set passive interfaces, verify neighbor.

Explore EIGRPv6 route summarization and default route advertisement in a hands-on lab, using classic and named mode configurations to propagate summarized routes between routers and learn default routes.

Set up a four-router OSPF lab with loopbacks, publish networks, manage passive interfaces, and observe DR/BDR election while testing reachability with ping.

Explore how to determine and configure OSPF DR and BDR selection using priority values, including commands like show ip ospf neighbor and interface ospf priority.

Learn how OSPF areas group interfaces into a shared link state database, with area zero as the backbone, and how intra- and inter-area routing, ABRs, and summarization work.

Configure a six-router ospf multi-area topology with area 1234 and backbone area zero, including an abr and specific subnets, then verify neighbors and inter-area routes with show commands.

Perform an ospf inter-area summarization lab on an abr between area 12 and area zero, configuring 172.16.0.0/16 and confirming a single summarized route with auto null route.

Understand OSPFv3 fundamentals, including IPv4 and IPv6 support, new LSA types, and link-based shortest-path calculations. Compare with OSPFv2, manual router IDs, and IPv6 neighbor discovery over link-local addresses.

OSPFv3 lab configuration explores setting router IDs, configuring border routers and area interfaces, and using loopback and link-local addresses to establish per-area OSPF processes.

Learn how the IS-IS link-state routing protocol operates in OSI networks, with level one and level two areas, NSAP addressing, and flexible type-length-value messages for scalable routing.

Explore is-is routing levels from level zero to level three, and how metrics such as default, delay, expense, and error drive independent SPF trees and level-specific adjacencies.

Learn how IS-IS uses hello, link state PDU, complete sequence number PDU, and partial sequence number PDU to detect neighbors, exchange routing data, and synchronize databases.

Configure isis level-1 routing between two routers in area 1 using authority id 49 and distinct system IDs, with a wide matrix and log agency changes.

Configure isis level 2 routing for inter-area communication between area one and area two, using passive interfaces, and verify neighbors and routes.

Configure IS-IS multi-area routing (l1-l2) across seven routers and areas one to three. Implement level one and level two adjacencies, summary addresses, and passive interfaces for efficient inter-area routing.

Enable ipv6 routing with IS-IS across routers three, four, and five, configuring ipv6 on interfaces and summarizing level-1 prefixes for level-2 neighbors.

Explains bgp fundamentals, including autonomous systems, ibgp and ebgp sessions, path attributes and as-path, mp-bgp address families, and the open, keepalive, update, notify messages with loop prevention.

Configure bgp across four routers by setting router IDs, establishing neighbors with as numbers, publishing ipv4 unicast prefixes under the address family, and activating peers; distinguish external from internal bgp.

Configure multiprotocol BGP (mp-bgp) across IPv4 and IPv6, set up neighbors and address families, publish prefixes including loopbacks, activate sessions, and verify with routing and show commands.

Learn to configure BGP route summarization across three autonomous systems (65.100, 65.200, 65.300) by aggregating 172.16.0.0/22 and validating the single summary advertised to neighbors.

Explore how the BGP best path algorithm selects routes by prefix length and tie-breakers, including weight, local preference, origin, med, and shortest AS path, shaping inbound and outbound traffic.
