Description

Set up a CARP VIP between two nodes.

Hmm. The old VIP was also not cleared from the interface - CARP INIT state. That is from the prior test in which I changed the VHID from 241 to 242.

Status > CARP shows MASTER/BACKUP

Change the VHID on the primary from 242 to 243. Save. Apply

Status > CARP Shows MASTER/ BLANK
