This course by PTT describes in detail the methods employed to dynamically choose routes for traffic over IP networks.
This course begins by describing the role of routing protocols and comparing distance vector and link state routing. The operation, advantages, limitations and applications of various routing protocols are then described including those used in autonomous systems (AS) and between AS. The traffic management facilities of the BGP inter AS protocol are explained. The course also discusses methods of increasing the efficiency of the routing process and IP address allocation with reference to subnet masking. The need for and advantages of IPv6 addressing are also discussed.
- Describe the use, operation and limitations of the distance vector routing protocol, RIP
- Describe the use and operation of the link state routing protocol, OSPF
- Describe the hierarchical routing and traffic engineering facilities offered by the link state routing protocol, OSPF
- Explain the concept, role and use of subnet masking
- Describe the role, advantages and principles of variable length subnet masking (VLSM)
- Describe the principles and advantages of route summarisation with reference to OSPF areas
- Describe the principles of Classless Inter-Domain Routing (CIDR) and its role in improving the efficiency of IP address allocation
- Explain the advantages of IPv6 addressing compared with IPv4
- Describe and compare protocols that advertise routing information between autonomous systems
- Describe the traffic management facilities of the routing protocol BGP with reference to load balancing and peering
- Explain the relationship between interior and exterior routing protocols with reference to redistribution and filtering
- Describe methods of protecting routing updates from malicious or fraudulent misuse with reference to MD5 authentication, IPsec and BGPsec
