Overview
This workshop provides hands-on experience on advanced topics in networking. It will focus on the Border Gateway Protocol (BGP) and Multi-protocol Label Switching (MPLS). BGP is the de facto standard inter-AS routing protocol in today’s Internet. As such, it is a critical protocol for the Internet—in essence, it is the protocol that glues the whole thing together. MPLS s a link-layer protocol that allows routers to forward packets based on fixed-length labels rather than the destination IP addresses. Today, many enterprise and ISP networks use MPLS to implement services such as Virtual Private Networks (VPNs) and Segment Routing.
Outcomes
By the end of this workshop, attendees will:
Border Gateway Protocol (BGP):
- Describe the operation of EBGP and IBGP sessions
- Analyze BGP authentication
- Configure and understand different BGP attributes
- Configure and verify Full Mesh IBGP
- Enable BGP route reflectors
MPLS and Advanced BGP Topics (BGP):
- Use MP-BGP functionality with IPv4 and IPv6 addresses
- Understand BGP Hijacking and mitigation technique
- Enable and verify MPLS implementation
- Use MP-BGP to exchange VPN routing updates
- Configure segment routing over IPv6
Intended Audience
The workshop is targeted to IT educators and professionals such as system administrators, network engineers, practitioners. The content is suitable for instructors who want to incorporate advanced material into their networking classes. The content is available for NETLAB systems.
Award Information
This activity is supported by NSF award 1829698. Link to official webpage: NSF-1829698
Pre-requisites
The laboratory environment consists of routers, switches, and hosts deployed in IPv4 networks. Attendees are expected to know basic networking (IPv4, local area networks, OSI model). Training activities will be conducted using NetLab. Attendees will be provided with a username and a password.
