I need to deploy a new network (the subnet will used will be the same as the existing subnet). At this stage I cannot change the existing network in place. It is currently using VLAN 1. The new core switches I will be deploying will use multiple VLANs, however the main VLAN for management, for example will be VLAN 100.
I have current equipment which is not cisco and are unmanaged. I do NOT at this stage want to rebuild the "now legacy network" with the new network management VLAN. The Legacy network will be designed and built at a later date.
Both VLAN 1 and VLAN 100 say for example will use network address 192.168.50.1 as the gateway address with network range 192.168.50.0/24
Is there a way to define VLAN 1 and VLAN 100 with the same ip address ?
or would it be better to do the following
IP address 192.168.50.1/24
IP address 192.168.50.2/24
IP address 192.168.50.1/24 secondary ?
Is this type of configuration supported on cisco ?. Inclusive of having the same subnet in VLAN 1 and VLAN 100 ?
Remove the IP address on VLAN 1 and make a new loopback interface. Give the IP of VLAN 1 to that new loopback interface and then on both VLAN 1 and VLAN 100, you can use the same IP address, as ip unnumbered loopback X.
