Comparing OSPF and EIGRP as IGPs

You need to choose one topic from the following list and carry out a mini-project.

1. Compare and contrast the differences between one specific IGP (for example, OSPF) and one specific BGP (for example iBGP or eBGP).

2. Compare and contrast the different path decision process between one specific IGP (for example, RIP) and iBGP.

3. Compare and contrast the differences between using BGP in the enterprise core (ALL three designs of Enterprise with BGP) and general ISP core.
4. Compare and contrast major differences between public peering and private peering
5. Discuss key reasons of the ISP design rule, “Once a customer, never a peer”.
6. Discuss in details of a challenge of exchanging path between two peers.

It is Strongly recommended but not required that an OpNet simulation is designed and implemented to support the discussions in your mini-project.

This assignment is to be completed individually.  You must submit a PDF file by the deadline.

Expected deliverables from each individual;

A short report: the maximum number of words is 1600 (not including, references and appendices).

To compare and contrast the differences between specific IGPs, let's take a look at OSPF and EIGRP.

1. OSPF (Open Shortest Path First)

• OSPF is a link-state protocol that calculates the shortest path based on the link-state database (LSDB) and the Dijkstra algorithm.
• OSPF allows for load balancing between equal-cost paths, which can increase network performance and resiliency.
• OSPF uses a hierarchical topology design that is more scalable than flat designs.
• OSPF is an open standard and widely implemented, making it easier to integrate with other network devices and vendors.
