With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?

Show Suggested Answer Hide Answer
Suggested Answer: A

Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network.If you have enabled active gateway, VRRP is not required3. Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches.The switch views the active gateway IP as a self IP address3.Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network3. Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

Wait, are VRIDs really set automatically? That sounds odd.

Definitely, VRIDs should be non-overlapping with VRRP.

I feel like I read that VRID is automatically assigned based on the SVI VLAN ID, but I’m not completely confident about that.

I believe VRRP and Active Gateway can work together, but I need to double-check if they can be on the same VLAN.

I think I practiced a question about VRIDs needing to be unique, but I can't recall if that applies to VRRP as well.

I remember that the Active Gateway feature is important for redundancy in VSX, but I'm not sure how it interacts with VRRP.

Okay, I think I've got this. The key is that Active Gateway is unique to VSX configurations, so it must be something specific to that environment. I'll focus on understanding how it works alongside VRRP.

Hmm, the wording is a bit technical. I'll need to make sure I understand the difference between VRRP and Active Gateway, and how they interact in a VSX setup.

The options mention VRRP and Active Gateway, so I'm guessing this has to do with redundancy and failover features. I'll need to review how those work in a VSX configuration.
