Advanced Junos Enterprise Routing (AJER)

( Duration: 3 Days )

The Juniper Advanced Junos Enterprise Routing (AJER) Training course is designed to provide Participants with the tools required for implementing, monitoring, and troubleshooting Layer 3 components in an enterprise network. Detailed coverage of OSPF, BGP, class of service (CoS), and multicast is strongly emphasized.

By attending Juniper Advanced Junos Enterprise Routing (AJER) workshop, Participants will learn to:

  • Describe the various OSPF link-state advertisement (LSA) types
  • Explain the flooding of LSAs in an OSPF network
  • Describe the shortest-path-first (SPF) algorithm
  • Describe OSPF area types and operations
  • Configure various OSPF area types
  • Summarize and restrict routes
  • Identify scenarios that require routing policy or specific configuration options
  • Use routing policy and specific configuration options to implement solutions for various scenarios
  • Describe basic BGP operation and common BGP attributes
  • Explain the route selection process for BGP
  • Describe how to alter the route selection process
  • Configure some advanced options for BGP peers
  • Describe various BGP attributes in detail and explain the operation of those attributes
  • Manipulate BGP attributes using routing policy
  • Describe common routing policies used in the enterprise environment
  • Explain how attribute modifications affect routing decisions
  • Implement a routing policy for inbound and outbound traffic using BGP
  • Identify environments that might require a modified CoS implementation
  • Describe the various CoS components and their respective functions
  • Explain the CoS processing along with CoS defaults on SRX Series Services Gateways
  • Describe situations when some CoS features are used in the enterprise
  • Implement some CoS features in an enterprise environment
  • Describe IP multicast traffic flow
  • Identify the components of IP multicast
  • Explain how IP multicast addressing works
  • Describe the need for reverse path forwarding (RPF) in multicast
  • Explain the role of Internet Group Management Protocol (IGMP) and describe the available IGMP versions
  • Configure and monitor IGMP
  • Identify common multicast routing protocols
  • Describe rendezvous point (RP) discovery options
  • Configure and monitor Protocol Independent Multicast (PIM) sparse modes
  • Configure and monitor RP discovery mechanisms
  • Describe the basic requirements, benefits, and caveats of source-specific multicast (SSM)
  • List the address ranges used for SSM
  • Illustrate the role of Internet Group Management Protocol version 3 (IGMPv3) and PIM sparse mode (PIM-SM) in an SSM implementation
  • Configure and monitor SSM

Participants should have:

The primary audiences for Juniper Advanced Junos Enterprise Routing (AJER) class are those individuals responsible for configuring and monitoring devices running the Junos OS.
