What is filter based forwarding?

Filter-Based Forwarding Overview. Firewall Filters That Handle Fragmented Packets Overview. Stateless Firewall Filters That Reference Policers Overview. Example: Configuring Filter-Based Forwarding on the Source Address. Example: Configuring Filter-Based Forwarding to a Specific Outgoing Interface or Destination IP …

Which routing instance type is used for filter based forwarding applications?

Forwarding. This instance type is used for Filter Based Forwarding (FBF).

What is filtering forwarding Juniper?

Filter-based forwarding enables you to configure packet filters that classify packets based on header information, such as IP source address, IP destination address, IP protocol field, and source and destination TCP/UDP port numbers.

What is VRF Juniper?

Use virtual routing and forwarding (VRF) to divide an EX Series switch into multiple virtual routing instances. VRF allows you to isolate traffic traversing the network without using multiple devices to segment your network. VRF is supported on all Layer 3 interfaces.

What are routing instances?

A routing instance is a collection of routing tables, interfaces, and routing protocol parameters. The set of interfaces belongs to the routing tables, and the routing protocol parameters control the information in the routing tables. Each routing instance has a unique name and a corresponding IP unicast table.

What benefits does policy-based routing provide?

PBR enables network administrators to classify the traffic based on applications and mark them for further analysis to provide greater visibility, enforcement, control, and protection to network security.

What is policy-based IPSec?

A policy-based VPN is a configuration in which an IPsec VPN tunnel created between two end points is specified within the policy itself with a policy action for the transit traffic that meets the policy’s match criteria.

Why VRF is used?

Virtual routing and forwarding (VRF) IP technology allows users to configure multiple routing table instances to simultaneously co-exist within the same router. Overlapping IP addresses can be used without conflicting because the multiple routing instances are independent, and can select different outgoing interfaces.

What is VRF target?

Also “vrf-target” field is used in order to add received routes to VRF (of course if vrf-target matches) and at the same time to advertise VPNv4 addresses to remote PE.
