Partition default route domain

I'm trying to configure a route domain to be a partition default, and each time I go to the route domain configuration I want to apply, and select the "Make this route domain the partition default route domain" option, the LTM comes back with "0107082e:3: The default route domain cannot be changed for the 'Test' partition." The Test partition contains the newly added route domain, and the VLAN(s) that I created for this route domain. Other than that, there's nothing defined in that Test partition.

 

 

From what I read in the documentation, for this to work the route domain being assigned must not reside in the Common partition. I've got that - the RD exists in the "Test" partition. I'd maybe expect to see this sort of error if anything else was configured in the partition, but these are real bare-bones sorts of things. If I delete the VLANs from the partition, that makes no difference. There are no self-IPs or floating-self-IPs in the partition or on those VLANs, no Nodes, no Pool Members, no virtual servers, etc.

 

 

It just doesn't seem to be working as described. What am I missing?

 

 

Also, and I hope there's a way around this - it appears that a route domain that isn't in the Common partition can only be assigned as the default in the partition it resides in. Is that the case, or can I assign the route domain to multiple partitions as their default route domain?

 

 

Thanks!
