Vlan on Another Switch

[chueymtz]

I have a host switch that has vlans configured on it, Vlan100 10.76.x.x, Vlan200 172.16.x.x, and Vlan300 192.x.x.x. My question is since I had to tie an ip address to the vlans of .x.1, if i need to use the same Vlans on different switches at other sites how do i go about them picking up those ip address from vlans? Ex: i have to setup a switch at the same location but from a fiber connection from a different building on the same site, do i have to apply a new ip address to those vlans of

if the SW is L2 and you have Core SW that do inter-vlan then 
config SVI for VLAN in Core only 
config SVI for one VLAN in other SW for management.

VLANs are unique per switch unless you connect a VLAN to another VLAN on another switch, using a L2 connection.

Network address assignments are assigned to VLANs.  They apply to that VLAN to wherever that particular VLAN is extended.

To be clear, a VLAN, on different switches is NOT the same VLAN unless, again, it's connected to other switches using the same VLAN (usually/almost-always switches would use the same VLAN number on different switches when VLANs between switches are interconnected).

E.g. SW 1 (VLANs 5 and 10) <port 20, VLAN 5 <> port 30 VLAN 5 > SW 2 (VLANs 5 and 10) - As VLAN 5 is interconnected on the two switches, its the same VLAN on both switches, while VLAN 10 is not, as it is not interconnected.

You could have: SW 1 (VLANs 5 and 10) <port 20, VLAN 5 <> port 30 VLAN 10 > SW 2 (VLANs 5 and 10) and now VLAN 5, on switch 1 and VLAN 10 on switch 2 are the SAME VLAN, BUT THIS IS HIGHLY UNUSUAL AND NOT RECOMMENDED.
