Juniper JN0-664 認定試験の出題範囲：

トピック	出題範囲
トピック 1	IP Multicast: Aspiring Juniper networking professionals explore the concepts and operations of IP multicast, including IGMP, PIM dense mode, and PIM sparse mode (including SSM). The topic focuses on configuration and monitoring techniques, enabling efficient delivery of multicast traffic across the network while optimizing resource utilization.
トピック 2	Layer 2 VPNs: Juniper networking professionals gain comprehensive knowledge of Layer 2 VPNs, including BGP Layer 2 VPNs, LDP Layer 2 circuits, VPLS, and EVPN. This topic focuses on configuring, monitoring, and troubleshooting Layer 2 VPNs, ensuring expertise in providing efficient and seamless layer 2 connectivity across service provider networks.
トピック 3	BGP: The concepts, operation, and functionality of Border Gateway Protocol (BGP) form the crux of this topic. Juniper networking professionals gain insights into BGP scaling mechanisms and develop expertise in configuring and monitoring BGP in complex scenarios. Mastery of BGP is vital for optimizing route distribution and achieving efficient inter-domain routing.
トピック 4	OSPF: In this topic, Juniper networking professionals delve into the core concepts and operations of OSPFv2 and OSPFv3. The focus is on configuring and monitoring single-area and multi-area OSPF scenarios. This ensures proficiency in managing link-state routing protocols and enhancing network efficiency. Understanding OSPF prepares the audience to address challenges in service provider environments effectively.
