Internet Courses for ISPs

Understanding Internet Routing

and Network Administration

Course Description

This course prepares students to implement Internet backbone routing, as well as the necessary components for network administration and support services. It covers BGP ISP backbone design and cover BGP routing details and filtering techniques that use AS-path, route maps and other BGP 4 attributes.


Course Duration

5 Days


Who Needs to Attend

Network administrators, Network Managers, Technical support personnel Internet product. Course will benefit those who need design and implement Internet routing policies.



Understanding TCP/IP Addressing course (TRN-UTCPIP) or its equivalent, plus a working knowledge of routed networks.
