Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References

Understanding Advanced Policy-Based Routing (APBR):

APBR: Allows routing decisions based on application-level information and policies.

Objective: Direct specific application traffic through different paths based on policies.

Routing Instances in Junos OS:

Forwarding Instance:

Used for features like filter-based forwarding (FBF) and APBR.

Provides a separate forwarding table but shares the global routing table.

Supports APBR.

Virtual Router:

Provides a separate routing table and forwarding table.

Used for logical separation of routing domains.

Does not support APBR directly.

Virtual Switch:

Operates at Layer 2.

Used for VLAN separation and Layer 2 switching.

Not applicable to routing or APBR.

Non-Forwarding Instance:

Used for management purposes.

Does not forward transit traffic.

Not suitable for APBR.

Option A: forwarding

Correct.

A forwarding routing instance is specifically designed to support advanced policy-based routing.

It allows the SRX device to direct traffic based on policies to different forwarding instances.
