About interface routing

Deploying Core : About interface routing

You configure interface routing by choosing Configure > Networking: Management Interfaces from the Core Management Console. If all the interfaces have different IP addresses, or have separate subnet IP address, you do not need additional routes.

This table shows a sample configuration in which each interface has an IP address on a separate subnet.

Interface	Example	Description
Auxiliary (AUX)	192.168.10.2/24	Management (and default) interface.
Primary (PRI)	192.168.20.2/24	Interface to WAN traffic.
eth0_0	10.12.5.12/16	Interface for storage array traffic.
eth0_1		Optional, additional interface for storage array traffic.
eth0_2	192.168.30.2/24	HA failover peer interface, number 1.
eth0_3	192.168.40.2/24	HA failover peer interface, number 2.

If all interfaces are in the same subnet, only the primary interface has a route added by default. You must configure routing for the additional interfaces. This table shows a sample configuration.

Interface	Example	Description
Auxiliary (AUX)	192.168.10.1/24	Management (and default) interface.
Primary (PRI)	192.168.10.2/24	Interface to WAN traffic.
eth0_0	192.168.10.3/24	Interface for storage array traffic.

If a subset of interfaces, excluding primary, are in the same subnet, you must configure additional routes for those interfaces. This table shows a sample configuration.

Interface	Example	Description
Auxiliary (AUX)	10.10.10.1/24	Management (and default) interface.
Primary (PRI)	10.10.20.2/24	Interface to WAN traffic.
eth0_0	192.168.10.3/24	Interface for storage array traffic.
eth0_1	192.168.10.4/24	Optional, additional interface for storage array traffic.

If some but not all interfaces, including primary, are in the same subnet, you must configure additional routes for those interfaces. This table shows a sample configuration.

Interfaces	Example	Description
Auxiliary (AUX)	10.10.10.2/24	Management (and default) interface.
Primary (PRI)	192.168.10.2/24	Interface to WAN traffic.
eth0_0	192.168.10.3/24	Interface for storage array traffic.
eth0_1	192.168.10.4/24	Optional, additional interface for storage array traffic.
eth0_2	20.20.20.2/24	HA failover peer interface, number 1.
eth0_3	30.30.30.2/24	HA failover peer interface, number 2.
