Change the VSX internal communication network

[Mattia_Varone]

Hi guys,

I have to setup 4 VSX cluster in HA mode, and I would like to modify the internal dedicated communication network for each one VSX cluster. The default network is 192.168.196.0/255.255.252.0, and is a very large subnet. Could be ok dedicate a /26 network for each cluster, or is it advisable configure networks with the same dimensions of the default internal communication network?

Thanks in advance.

Refer to Changing the VSX Cluster Internal Communication Network.

Kinda misread the question 😬

I think you probably want to keep the network size the same. Since it should be only routable within a given cluster, this begs the question why you want to make it unique on each cluster.

Hi,

customer has the subnet 192.168.196.0/22 in his network, and I prefere to change from the defaul network to a new one. But following this discussion I'm going to choice a new /22 subnet, that I'll configure on all my VSX cluster, and not a dedicated subnet to each one VSX cluster.

Thanks for the suggestion

You can change it only to a larger subnet mask.

Hi,

thanks for your suggestion, so is better reserve a network at least a /22 mask.
