[pve-devel] [PATCH docs] pvecm: redundancy: explicitly mention subnets

[Friedrich Weber]

The section uses addresses 10.10.10.X and 10.20.20.X in examples and
implicitly assumes they are in disjoint subnets, but does not
explicitly state this.

For better clarity, explicitly mention these are /25 subnets (this
subnet mask is also used in the "Separate Cluster Network" section).
