General System Features




The first section of the JNCIE SP preparation workbook covers the general system features that are tested in the exam. These features include initial system settings, SNMP configuration, firewall filters, interface configuration, and scripting. You will learn how to perform basic system administration tasks, such as setting the hostname, domain name, root password, and time zone. You will also learn how to configure SNMP agents and traps, firewall filters for control plane protection and packet filtering, interface parameters and options, and scripts for automation and customization.


The general system features section of the workbook contains several configuration tasks and troubleshooting scenarios that will help you master these topics. For example, you will have to configure SNMPv3 with authentication and encryption, apply firewall filters to protect the routing engine and the loopback interface, configure interface descriptions and MTU values, and write a script to monitor interface status and send an email notification. You will also have to troubleshoot issues such as incorrect system settings, missing firewall filters, mismatched interface parameters, and faulty scripts.


The general system features section of the workbook will help you understand the basic concepts and commands that are essential for any network engineer working with Juniper Networks devices. You will also gain confidence in configuring and troubleshooting these features in a service provider network environment.


IGP Configuration and Troubleshooting




The second section of the JNCIE SP preparation workbook covers the IGP configuration and troubleshooting topics that are tested in the exam. IGP stands for Interior Gateway Protocol, which is a type of routing protocol that is used to exchange routing information within an autonomous system (AS). The exam focuses on two IGPs: OSPF and IS-IS. OSPF stands for Open Shortest Path First, which is a link-state routing protocol that uses the Dijkstra algorithm to calculate the shortest path to each destination. IS-IS stands for Intermediate System to Intermediate System, which is also a link-state routing protocol that uses the Dijkstra algorithm, but with a different packet format and hierarchy structure.


The IGP configuration and troubleshooting section of the workbook teaches you how to configure and troubleshoot OSPF and IS-IS protocols on Juniper Networks devices. You will learn how to enable OSPF and IS-IS on interfaces, configure areas and levels, adjust metrics and timers, enable authentication and graceful restart, and optimize routing performance and scalability. You will also learn how to implement IGP rollout, which is a technique that allows you to migrate from one IGP to another without disrupting traffic.


The IGP configuration and troubleshooting section of the workbook contains several configuration tasks and troubleshooting scenarios that will help you master these topics. For example, you will have to configure OSPF in a multi-area network with stub areas, virtual links, route summarization, and external routes. You will also have to configure IS-IS in a multi-level network with discontinuous areas, route leaking, route summarization, and wide metrics. You will also have to troubleshoot issues such as adjacency failures, routing loops, suboptimal paths, and route flapping.


The IGP configuration and troubleshooting section of the workbook will help you understand the similarities and differences between OSPF and IS-IS protocols, as well as their advantages and disadvantages in service provider networks. You will also gain confidence in configuring and troubleshooting these protocols in complex network scenarios.


BGP and Routing Policy




The third section of the JNCIE SP preparation workbook covers the BGP and routing policy topics that are tested in the exam. BGP stands for Border Gateway Protocol, which is a type of routing protocol that is used to exchange routing information between different autonomous systems (ASes). BGP can be classified into two types: IBGP and EBGP. IBGP stands for Internal BGP, which is used to exchange routing information within an AS. EBGP stands for External BGP, which is used to exchange routing information between different ASes.


The BGP and routing policy section of the workbook teaches you how to configure and troubleshoot IBGP and EBGP on Juniper Networks devices. You will learn how to establish BGP sessions with peers using TCP port 179, exchange network reachability information using BGP messages, apply routing policies to control route advertisement and acceptance using terms and actions, configure confederation to reduce IBGP mesh complexity using sub-ASes, and configure route reflection to reduce IBGP mesh complexity using route reflectors.


The BGP and routing policy section of the workbook contains several configuration tasks and troubleshooting scenarios that will help you master these topics. For example, you will have to configure IBGP sessions with confederation using sub-AS numbers, route reflection using clusters, route damping using penalties and thresholds, multipath load balancing using weights and preferences, MED-based outbound traffic engineering using AS-paths with route aggregation using communities and AS-sets, route filtering using prefix lists and AS-paths, local preference-based inbound traffic engineering using communities and actions, and multihop EBGP using loopback addresses and next-hop resolution. You will also have to troubleshoot issues such as session failures, route advertisement and acceptance failures, routing loops, suboptimal paths, and traffic imbalance.


The BGP and routing policy section of the workbook will help you understand the fundamental concepts and operations of BGP, as well as its role and importance in service provider networks. You will also gain confidence in configuring and troubleshooting BGP and routing policies in various network scenarios.


MPLS Configuration




The fourth section of the JNCIE SP preparation workbook covers the MPLS configuration topics that are tested in the exam. MPLS stands for Multiprotocol Label Switching, which is a technique that uses labels to forward packets across a network. MPLS can be used to implement various services, such as traffic engineering, fast reroute, VPNs, and QoS. MPLS relies on two protocols to establish label-switched paths (LSPs) across a network: LDP and RSVP. LDP stands for Label Distribution Protocol, which is a protocol that distributes labels based on the IGP routing information. RSVP stands for Resource Reservation Protocol, which is a protocol that reserves resources and distributes labels based on the traffic engineering requirements.


The MPLS configuration section of the workbook teaches you how to configure and troubleshoot LDP and RSVP on Juniper Networks devices. You will learn how to enable MPLS on interfaces, configure LDP parameters and options, verify LDP operation and label bindings, configure RSVP parameters and options, verify RSVP operation and label reservations, configure RSVP protection mechanisms such as link protection and node protection, and configure IPv6 tunneling with 6PE.


The MPLS configuration section of the workbook contains several configuration tasks and troubleshooting scenarios that will help you master these topics. For example, you will have to configure LDP in a multi-area network with route summarization, LDP over RSVP tunnels, LDP over GRE tunnels, LDP over IPv6 tunnels, and LDP over BGP-LU tunnels. You will also have to configure RSVP in a mul
