When trying to manage juniper ISG2000 and SSG550 under screenOS 6.2.0r9 we can select default VR and/or management VR on the NSM window. . When we select a VR as management VR , it automatically changes the value of default VR to the onr choosen as management VR on the NSM screen and vice versa. . Is this behavior normal ? It is an NSM bug ?
