Do F5s continue to advertise virtual server IPs after they have been disabled or deleted?

I've been doing a migration from a pair of 1500s running 10.2.4 to a pair of 5000's running 11.4.1.   After disabling the virtual servers on the old HA pair I enabled them using the same IP addres...

    The LTM should not respond to ARP requests for an IP address assigned to a disabled virtual server. I'm guessing that something is cached within your network, or something is still enabled when it shouldn't be on your 1500s.

Thanks Cory, that was my thinking re the 1500s. I can't see why they would be advertising a disabled virtual server.

 

I would be interested to know what might still have been enabled on them which shouldn't have been. Can you (or anyone else) elaborate?
