VLAN-Groups Self IP Assignment vs. Supernet
Hello all. I am struggling to understand two things regarding VLAN groups. The documentation provides two possible use cases:
Grouping multiple VLANs into a container so the servers within member vlans see themselves rather within one VLAN
Allow client and server to communicate when they are on the same IP range
So I've got a issues regarding each of the scenarios above:
Q1: If one VLAN 10 uses 10.1.2.0 /24 and VLAN 20 uses 10.12.3.0 /24, what would the VLAN-Group self IP would be? My understanding is that the IP address & mask should include both VLANs above! Does this then mean I need to super net the two? This could be tricky in some scenarios where discontiguous networks are being used?
Q2: What would be a realistic use case of the second scenario??
thank you so much.
