Details

Yes:

Overlapping subnets are supported only when each overlapping interface/sub-interface is in a separate virtual router.

For example:

Virtual Router1: 192.168.1.1/24

Virtual Router2: 192.168.1.2/24

 

No:

Duplicate host IP addresses are not supported

 

If overlapping subnets are not in separate virtual routers, the following error will be prompted and the commit will fail.
