Consolidating 3 VLAN's into 1
Hello,
I currently have 3 VLAN's that I am managing for the same building. I want to change this to be one VLAN and one scope. I currently have these networks:
VLAN1 192.168.0.0 /24
VLAN2 192.168.1.0 /24
VLAN3 192.168.2.0 /24
I want to remove VLAN2 and VLAN3 and make VLAN1 a /22 to accompany all of the VLAN2 and 3 addresses.
My hope is that the static IP's in VLAN2 and VLAN3 would still communicate through VLAN1 with the new scope. I would need to re-tag all of the switches in VLAN2 and VLAN3.
Would this work? Has anyone done anything like this before? I am wondering the best order to do this in.
1. Disable Scope for vlan 2 & 3
2. Re-configure VLAN1 to /22
3. Switch tags from 2 & 3 to VLAN1
4. Test connectivity

But all your static IP's on systems have to have the new netmask /22 they need the new netmask in order to calculate the new broadcast address 192.168.3.255

Re: Consolidating 3 VLAN's into 1
You are right. I was hoping I didnt have to do that because of our old novar controllers. I will have to figure out how to switch their subnet mask.
Thanks for the reply!
