Exam JN0-104 topic 1 question 28 discussion

forwarding: Used to Implement filter-based forwarding for common Access Layer applications: • l2vpn: Used In Layer 2 VPN implementations; • no-forwarding: Used to separate large networks Into smaller administrative entities: • virtual-router: Used for non-VPN-related applications such as system virtualization: • vpls: Used for point-to-multipoint LAN Implementations between a set or sites In a VPN: and • vrf: Used in Layer 3 VPN Implementations. -------------------------------

The Junos OS routing instance type used for non-VPN-related applications such as system virtualization is called the "Virtual Router" routing instance. The Virtual Router routing instance is specifically designed for system virtualization and allows for the creation of independent virtual routing instances within a single physical router. Each virtual routing instance operates as a separate routing entity with its own routing tables, routing protocols, and forwarding tables. By utilizing Virtual Router instances, different virtual environments or tenants can be hosted on the same physical router while maintaining separation and isolation of their routing information and policies. This makes it an ideal choice for non-VPN-related applications such as system virtualization.

Ref: Routing Instances Overview | Junos OS | Juniper Networks "Routing Instances Overview ... You can configure 13 types of routing instances: ... Virtual router—Similar to a VPN routing and forwarding instance type, but used for non-VPN-related applications. There are no virtual routing and forwarding (VRF) import, VRF export, VRF target, or route distinguisher requirements for this instance type. ..."
