Learning objectives
Explain the fundamentals of MPLS and Layer 3 VPNs, including their architecture, key components (PE, CE, and P routers), and primary use cases for enterprises and service providers.
Configure and verify Virtual Routing and Forwarding (VRF) instances on PE routers to establish an MPLS L3VPN, integrating CE-to-PE routing options like static and dynamic protocols.
Deploy Multiprotocol BGP (MP-BGP) to exchange routes between PE routers, utilizing Route Distinguishers (RDs) and Route Targets (RTs) to manage VPN connectivity.
Troubleshoot common MPLS L3VPN issues using appropriate tools and techniques, such as verifying label switching and connectivity across PE-CE links.
Design an MPLS L3VPN deployment, incorporating common topologies like hub-and-spoke and full mesh, while addressing routing and connectivity requirements.
