Thoughts and Query
I was tring to understand Inter-vlan routing and realised, that each exsisting vlan in the switch is configured with a different subnet.
Is this is a good practice or is there any specific reasons,like what are the advantages of doing this(as each vlan is in itself a separate subnet...just an analogy)
Any thoughts would be helpful.
Vlans are layer two constructs. Subnets are layer three constructs. In all but a very few exceptions, you have one subnet per VLAN and vice versa.
Most probably you have Router on a stick situation when single router is doing the routing for all these vlans.
Here you are a link to get the idea:
Basically you can't have overlapping IP addressing on a single router (ignoring VRFs)
