Configure rip version 2 with no auto-summary on all routers and set passive interfaces on router 3, then review show ip routes and cef concepts.

Configure and compare OSPF with RIP in a Cisco Packet Tracer lab, using area 0, wildcard masks, and network commands to establish adjacencies and verify routing with show ip route.

Learn how OSPF uses areas and a backbone area 0, with ABRs, to share topology and compute path costs from interface costs.

Learn how EIGRP, a Cisco proprietary distance vector protocol, uses dual algorithm to select the best path by bandwidth and latency. Understand neighborship, topology, and routing tables for route management.

Explore the basic concepts of frame relay and how to configure a point-to-point frame relay network in Cisco Packet Tracer, including PVCs, DLCIs, and CSU/DSU connections to a provider cloud.

Explore multipoint frame relay, compare it with point-to-point setups, create a single multipoint sub interface in the same broadcast, and configure RIP for two networks with DLCIs.

Configure multipoint and point-to-point frame-relay links with DLCIs and subinterfaces, set 10.1.0.1/29 and 10.4.0.2/30, then verify routing with rip version 2.

Explore configuring multiple-area OSPF across three areas, including area 0 backbone, area border routers, and inter-area routes, by advertising networks and validating neighborship with show ip route and ping.

Learn to configure OSPF authentication between routers in a multiple-area network, first with clear-text passwords and then with MD5 hashing, and verify with show running-config.

Configure loopback interfaces on multiple routers in Cisco Packet Tracer, assign /32 IPs for each router, verify the loopback addresses, and save the lab for the next exercise.

Learn how to create a precise OSPF summary for a LAN by extracting the common bits of its subnets with binary math and applying a single, exact mask.

Calculate the summary address for area 0 using the common bits, configure ospf area 0 range 10.0.96.0 255.255.248.0, advertise the summary ip, and verify with show ip route and ping.

Learn to configure BGP as the exterior gateway protocol, exchange routes between autonomous systems, advertise networks with mask, and establish neighbor relationships to propagate the global BGP table.

Practice basic BGP configuration in a Packet Tracer lab by setting static routes, configuring BGP on multiple routers, and advertising internal networks with neighbors.

Configure RIP version 2 and OSPF with area 0, then redistribute between RIP and OSPF, using subnets and a metric to translate routes across protocols.

Implement standard access lists in Cisco Packet Tracer to deny host 10.0.0.5, block 12.0.0.0/24 to 14.0.0.0/24 traffic, and restrict telnet on line vty 0-15.

Learn to configure extended access lists in Cisco Packet Tracer, ban specific hosts and networks, apply ACLs to interfaces, and insert rules to block telnet traffic.

Explore NAT and PAT concepts with practical examples, using private to public IP translation, static and dynamic NAT, and port address translation to conserve public addresses.

Configure dynamic NAT (PAT) and static NAT to translate private 192.168.0.0/24 and 192.168.100.0/24 to public addresses, using inside and outside interfaces.

Configure ip addresses on all router interfaces and PCs, set up dhcp servers and pools for hfc and dsl networks, implement static nat for servers, and configure dhcp clients.

Configure dynamic and static NAT on HFC and DSL homes, set up inside and outside interfaces, and implement OSPF, EIGRP, and BGP routing with default routes and route propagation.

Configure BGP across multiple autonomous systems, redistribute OSPF and EIGRP into BGP, fix missing EIGRP config, and validate routes with ping in a Packet Tracer lab.

Configure standard and extended ACLs in Cisco Packet Tracer to permit only 13.0.81.0 and 183.2.0.0 for telnet, and block http traffic from 33.0.0.0, applying to the telnet line and interface.

Learn to configure OSPF and HSRP across routers in Cisco Packet Tracer, set a virtual gateway IP of 192.168.1.1, and test failover with track and preempt features.
