Virtual IP addresses

Not planned

Hi,

It would be useful to have a special type of IP address, a virtual address that can be allocated to more than one device.

Let's say for example I have a couple of routers running HSRP and have a shared virtual IP.  At the moment I can create a cluster device representing the virtual IP feature of that device, but that isn't ideal for a couple of reasons:

• since it isn't really a cluster as such I need to invent a name and generally represent a device in IPAM that isn't really in my network just so I can have that virtual IP allocated somewhere
• devices are expensive!  These pretend cluster devices really eat up our device entitlement for not much real value

There's probably other situations where virtual IPs would be useful, e.g. anycast deployments?

  Hello Valued Customers-

  We are working on this. We have an internal request open to address this in an upcoming release. I will keep everyone updated on the status, thanks for the input and the patience!

  Hugh,

  I see your point. Although, assigning two devices to an IP will break some logic in d42, we can probably represent this in some other way. We will discuss this internally more and reach out to you as we have more questions.

  Was this issue ever addressed?  We use virtual IPs on our load balancers.  The IP is associated to a service (i.e. web site), but can exist on any of our load balancers.  

  If there's not a way to associate the same IP to multiple devices, perhaps there's a way to define "applications/service" as a device so that an IP address can be assigned to them?  That "application/service" wouldn't take on the same characteristics of a regular device, but it's still assigned an IP address.

  Some of IP addresses can be shared between network devices. For example every first hop redundancy protocol (HSRP, GLBP, VRRP, ..) allow you share IP in such way.

  I would like new type for IP address as 'virtual' and ability to tie such IP address more then to one device (currently you can select only device).

  This is something I have been trying to workaround for the same reasons mentioned above. Just adding my +1 to this topic.

  Same problem here.

  There's not an easy way to create a virtual IP, or an anycast IP, that may be configured in more than 1 device. I'd like to see this being addressed.

  Over 7 years ago this was mentioned...wow. Jason responded two years ago that this was in the works. I would think there should be some kind of update on this by now??

   

  this would be very beneficial to the Commonwealth of PA
