Interface configuration

Platform discussions

Dear Support,
in the interface configuration there is as expected a field for each network parameter needed to set up a NIC: IP address of the card, mask and gateway. Is it good practice to assign the gw information on all NICs? Is there a way to set up the gw on one interface only (I am thinking at the MGMT network) and set up static routes for the other NICs (with the gw information and the eth port to use as well).
Kind regards
Mauro

Dear @Mauro_Zambrano , It is generally not recommended to assign the gateway information on all NICs. Instead, it is a common practice to set the gateway on one interface, typically the management network, and use static routes for other NICs. This approach helps in managing traffic more efficiently and avoids potential conflicts that can arise from having multiple gateways.
To set up the gateway on one interface only and use static routes for other NICs, you can follow these steps:

  1. Assign the Gateway to the Management NIC: Configure the default gateway on the management NIC. This will be the primary route for outbound traffic.
  2. Configure Static Routes for Other NICs: For other NICs, you can define static routes that specify the gateway and the interface to use for specific network destinations. This involves adding route entries that direct traffic for certain IP ranges through the desired NIC and gateway.
  3. Verify Routing Table: After configuration, ensure that the routing table reflects the desired routes and that traffic is being directed correctly.

This setup allows you to control the flow of traffic and ensures that each NIC handles the appropriate network segments without interference from multiple default gateways

Hi Ori.
Where can I assign static routes? Do I need to SSH to the unit or through IDRAC access?
Kind regards

Dear @Mauro_Zambrano the currently there is no option to add static route to the MCM but we are improving our software to work better with multiple default gateways

Our recommendation is - if you can avoid having multi gateways - please do
if not you can configure gateway on any interface

Thanks Ori.
Have a nice day.
