HPE7-A01 practice question 4 of 25

You need to have different routing-table requirements with Aruba CX 6300 VSF configuration Assuming the correct layer-2 VLAN already exists how would you create a new OSPF configuration for a separate routing table?

Full set: 117 questions
Answer options
A: Create a new OSPF area, and attach VRF name.
B: Create a new OSPF process ID with vrf name. Correct answer
C: Attach a new OSFP process ID with a custom routing table
D: Attach OSPF process ID in the VRF configuration.
Correct Answer:
B. Create a new OSPF process ID with vrf name.
Explanation

To achieve separate routing tables on Aruba CX switches, Virtual Routing and Forwarding (VRF) instances are used. Each VRF maintains an independent routing table. To enable OSPF for a specific VRF, a new OSPF process must be created and explicitly associated with that VRF. The command router ospf vrf instantiates a new OSPF process that operates exclusively within the context of the named VRF, populating its unique routing table. This isolates its routing information from the default routing table and other VRFs.

Why Incorrect

A. OSPF areas are used for hierarchical segmentation within a single OSPF domain to improve scalability; they do not create separate routing tables.
C. The standard feature for creating separate, isolated routing tables is VRF, not a generic "custom routing table." This option lacks the required technical precision.
D. The configuration is performed by creating an OSPF process and assigning it to a VRF, not by attaching a process from within the VRF configuration context.

1. ArubaOS-CX 10.12 Virtual Routing and Forwarding (VRF) Guide

"Configuring OSPFv2 for a VRF" section. The guide explicitly shows the command sequence for enabling OSPF on a non-default VRF

which starts with router ospf vrf . This directly supports creating a process ID with a VRF name.

2. ArubaOS-CX 10.12 IP Routing Guide

Chapter "OSPFv2"

Command Syntax section. The syntax for initiating an OSPF process is documented as router ospf [vrf ]. This confirms that the VRF is specified at the time of process creation to link it to a non-default routing table.
