This course provides a detailed examination of the JUNOS software policy framework. The course begins with a quick review of policy basics and then quickly moves to advanced topics. It provides detailed discussions of load balancing, policy evaluation, and route creation. How routing policies affect the interior gateway protocols as well as multicast routing are examined.
The complexities of implementing and using policies in relation to BGP are explored where the discussion centers on the default behavior of the basic BGP attributes and their response to policy controls. Most course modules provide examples and use policies that are relevant in real-world networks. Students then implement those examples in the accompanying labs.

Specific topics include:

• Routing Policy
• Policy Configuration
• Applying Policies
• Renaming Terms and Policies
• Testing a Routing Policy
• Routing Tables
• Default Route Preference
• Filtering Routes from Forwarding Table
• Policy Between RIB Groups
• Aggregate Routes
• Configuring Aggregate Routes
• Generated Routes
• Route Filters
• When Order Does Count
• JUNOS Software Load Balancing
• Network Flows
• Load-Balancing Policies
• BGP Load Balancing
• Multiple Policies
• Configuration Groups
• Subroutines
• Policy Expressions
• Controlling Policy Order
• Policy Expression Logic
• Forwarding Class Override
• Forwarding Using CoS
• Interior Gateway Protocols (IGP)
• Sourcing Routes in RIP
• Open Shortest Path First Protocol
• Sourcing Routes in OSPF
• Intermediate System-to-Intermediate System Protocol
• Multicast Policies
• Multicast Source Discovery Protocol
• Multicast Forwarding
• Multicast Scoping
• Policy Scoping
• Configuring a Policy Scope
• Border Gateway Protocol (BGP)
• BGP Policy
• BGP Import Policy
• BGP Export Policy
• BGP Origin Attribute
• Multiple Exit Discriminator
• More Complex Use of MED
• AS Paths
• Regular Expressions and BGP Routes
• BGP Attributes: Local Preference

• Students should be able to configure basic RIP, OSPF, IS-IS, and BGP networks without assistance.
• Students should have knowledge of the JUNOS Internet software policy syntax to the extent covered in the Configuring Juniper Networks Routers (CJNR) or the Introduction to JUNOS Software (IJS) courses.
