Configuring Multiple VNICs for Roving Edge Infrastructure Devices

When you create multiple virtual network interface cards (VNICs) on your instance using Oracle Cloud Infrastructure, you can use the script secondary_vnic_all_configure.sh to configure them. The script also configures jumbo maximum transfer unit (MTU) on secondary VNICs.

You can use this same script when creating multiple VNICs for an instance created on a Roving Edge Infrastructure device. Download this script to your instance before disconnecting your device from the network. Run this script each time you reboot the instance by adding the script to a service file. Then enable the service to run on boot.

If your instance is configured with multiple VNICs, Oracle recommends that you configure default.rp_filter to either 0 (no reverse path filtering) or 2 (loose mode of reverse path filtering) in their instance so that any of the public IP's assigned to the VNICs can access the instance.
