Routing problems with Intercluster LIF

Hello,

 

in a small environment i have a 2 node system and a single node system in a remote office connected via vpn. I make daily snapmirror updates through that vpn.

 

I have now a problem:  How to make a every time working Intercluster configuration.

 

When the intercluster is in the same IP subnet as the management interfaces, i got problems, that sometimes services (like Autosupport) can use the intercluster IP as source and not the node management LIF. (Documented in the network management guide)

 

So i configured a own management network, with ONTAP 9.1 all was fine, but after a upgrade to 9.2 i can't reach the SSH and HTTP services on the management interfaces from clients in the same subnet as the Intercluster LIF.

 

Subnet A - NetApp Management interfaces

Subnet B - Intercluster and also some Clients

 

With enabled Intercluster in Subnet B i can ping the Management interfaces in Subnet A from Subnet B from a client, but can't use SSH or HTTP. When i disable the Intercluster i can connect via SSH or HTTP.

 

As a workaround i made now 3 subnets, a own subnet for Intercluster.

 

But can that be correct, that the management isn't useable when a Intercluster is present in the source network?

 

Kind regards

Stefan

I'm having the same issue.  You ever find a fix for this?

The source of the problem is the removal of IP fastpath in 9.2:
