7.7 Configuring OSPF

7.6 Open Shortest Path First (OSPF) Basics

• OSPF is an open standard routing protocol
• OSPF works by using the Dijkstra algorithm
• OSPF features:

1. Consists of areas and autonomous systems
2. Minimizes routing update traffic
3. Allow scalability
4. Support VLSM/CIDR
5. Has unlimited hop count
6. Allow multi-vendor deployment (open standard)

7.5 Verifying EIGRP

• EIGRP troubleshooting commands:

7.4 Load Balancing with EIGRP

7.3 Configuring EIGRP

• EIGRP can be configured through two modes:

1. Router Config Mode
2. Interface Config Mode

• Router config mode enables the protocol, determines which networks will run EIGRP, and sets global characteristics
• Interface config mode allows customization of summaries, metrics, timers and bandwidth
