my existing LAN set up have a subnet: 153.117.182.0/24. It is a flat network...no VLAN configured. I want to configure a VLAN, say VLAN 2 with a different subnet: 153.117.183.0/28. VLAN 2 needs to communicate to file servers belonging to the subnet 153.117.182.0/24.
These file servers should be both accessible to the two subnets VLAN1 hosts and VLAN2 hosts. Traffic from VLAN2 is only within VLAN2 and VLAN1..no outside traffic.
I have a core CAT3550 L3switch where I plan to set up as a vtp server. Create VLAN2. At this switch, the file servers are connected.
Another switch, CAT2960, is cascaded and connected via trunk(802.1Q) to CAT3550.
At CAT2960, I have configured 4 ports for VLAN 2 and 1 port for trunking to CAT3550.
-Please help me to verify if my design is feasible.
-Is my assumption correct that native/default VLAN 1
(in my LAN's case my host and server subnet--153.117.182.0/24) can communicate to VLAN 2 subnet--153.117.183.0/28
please refer to the attached text file for my proposed config. Thanks in advance!

Hi ,
Both are directly connected subnets so Vlan 1 and Vlan 2 will communicate with each other.

Hi Emmanuel ,
Configuration is as below according to your requirement :
3550 :
Ip routing
vtp domain cisco
vtp passord cisco
vtp mode server
interface Vlan1
ip address 153.117.182.3 255.255.255.0
!
int vlan 2
ip address 153.117.183.1 255.255.255.240
no shut
end
interface FastEthernet0/48
description ***connecting to 2960 Switch***
switch port trunk encapsulation dot1q
switchport mode trunk
2960 switch:
vtp domain cisco
vtp passord cisco
vtp mode client
int vlan 1
ip address 153.117.182.4 255.255.255.0
no shut
end
int fa0/1
Description**connecting to 3550 ***
switch port trunk encapsulation dot1q
switchport mode trunk
exit
ip deafult-gateway 153.117.182.3
as there is a trunk b/n both the switches you can place few hosts in vlan 1 on 2960 switch if required.
Thanks,

Hi Satish,
Thanks for your reply! Just to clarify, so in these configs, vlan2(153.117.183.0/28) can communicate to servers in vlan1(153.117.182.0/24) and vice versa right?
