Create an IP Transit HA Instance

This chapter guides you through creating an IP Transit HA instance in zenConsole.

Go to zenConsole → Network → IP Transit, click Buy in the upper-right corner, and follow the steps below.

Procedures

1

Enable HA

In the High Availability (HA) section on the creation page, turn on the Enable HA toggle.

Enable HA toggle

Hover over the ⓘ icon to view the description:

• If the primary port fails, traffic automatically switches to the standby port within seconds.

• An HA instance requires two co-located ports.

2

Select an Operating Mode

Under HA Operating Mode, select one of the following:

• Active-Standby: The primary port carries all traffic and switches to the standby port within seconds on failure. Best for workloads requiring deterministic routing paths.

• Active-Active: Both links forward traffic simultaneously using ECMP, maximizing bandwidth utilization.

Select an operating mode

3

Configure Ports

In the Select Ports section, select ports and configure VLANs:

1. Select the first port. The system automatically designates it as the primary port.

2. Select the second port. The system filters the list to show only ports in the same city as the primary port; ports in other cities are grayed out.

3. Enter a VLAN ID for each port (using the same VLAN ID for both is recommended).

Select ports and configure VLAN IDs

4

Configure IP Transit Parameters

Fill in the following parameters:

• Target region

• IP stack: IPv4 / IPv6 / Dual-stack

• IP type and address block size

• Billing model: Flat Rate or Burstable 95th

• Bandwidth specification: Both links are configured with the same specification

Configure IP Transit parameters

5

Confirm and Place the Order

Review the order summary (the system generates a single unified order covering both port resources) and click Buy Now to complete payment.

Note

If either port fails to provision after the order is submitted, the system automatically rolls back the entire order and reports a creation failure.

What to Do Next

After creation, the HA instance appears in the IP Transit list with an HA badge. Go to the instance details page to view traffic monitoring, port status, and the current operating mode.

See View HA Instance for details.
