HI All,

May i know Could fortiGate support configure redundant interface with LACP for full mesh HA?

Thanks

Hi,

Could you please advise if you are looking for Aggregate interface (LACP) or redundant interface. Both of these are two different methods and have different outcomes. Both can be used in a Full Mesh HA.

Hi 

Would like to know could both feature combine together in full mesh HA

Hi,

You can have separate Physical interfaces in Aggregate interface and Redundant interface and use them as part of your setup but you cannot combine them (Ex: Using redundant interface as a member of Aggregate interface) because of below reasons.

An interface is available to be an aggregate interface if:

• It is a physical interface and not a VLAN interface or subinterface.
• It is not already part of an aggregate or redundant interface.

An interface is available to be in a redundant interface if:

• It is a physical interface and not a VLAN interface.
• It is not already part of an aggregated or redundant interface.

Correct me if my understanding of your requirement is wrong.

HI,

Understood Aggregate interface and Redundant interface both feature not allow combine in a same group of physical interface. Must separate configure the feature with different physical interface.

Please correct me if 'm wrong understanding.

Hi,

Your understanding is right.
