Cannot access from vlan switch to non vlan switch

[Edward999]

Hi I have 2 5324 dell switch with a core switch.

The first Dell switch have no vlan meaning only vlan 1 (Default vlan).I have a email server and DHCP server connected to this Dell switch. My email server having 10.0.1.1 and my DHCP server ip address is 192.168.1.33 This two server having a static ip address.

The second dell server have 10 vlan. My PC connected to this vlan 110 having an ip address 10.0.2.1 from DHCP.

I have a core switch 3550 connected to two 5324 Dell switch.
The first Dell switch have no "trunking with 802.1q" on 3550 port.
The second Dell switch have "trunking with 802.1q" on 3550 port.

So how to access my email server from my PC?. Actually i need to be able to access my email server for all of my vlan on second Dell server. I try to ping to email server which is 10.0.1.1 and my DHCP 192.168.1.33 and i'm getting request time out.

Please help....

Thanks in advance

First, make sure you turn on IP routing by the command "ip routing".

Create all the VLANs in 3550, then create all the VLAN interfaces with corresponding IP addresses which will be the gateway of that VLAN.

e.g. VLAN 110 subnet is 10.0.2.0/24, then config the interface VLAN 110 with an IP address say 10.0.2.254/24. Also use "ip helper-address [DHCP server IP]" on every VLAN interface that doesn't have a DHCP server on that subnet. Then in your DHCP scope define the default gateway of this scope to 10.0.2.254.

Sample config:

!
ip routing
!
vlan 110
!
interface vlan 110
ip address 10.0.2.254 255.255.255.0
ip helper-address 192.168.1.33
!

or in older IOS:

!
ip routing
!
vlan data
vlan 110
apply
exit
!
interface vlan 110
ip address 10.0.2.254 255.255.255.0
ip helper-address 192.168.1.33
!

Hi Thanks for your reply. I can ping to my DHCP server already after i turn on the IP routing.

I still cannot ping to my email server static ip 10.0.1.1 and the ping result i'm getting is "destination unreachble"

I ping from my PC with ip address 10.0.2.1 connected to vlan 110 dell switch.

I already created all the vlan interface in cisco 3550 and i manage to get ip address from the DHCP server.

I really have no idea?

Thanks again

how about the VLAN for 10.0.1.0?

I can see that you have email server and DHCP server which belong to different subnets/VLANs but all connected to the same switch with only VLAN 1.

Maybe you should create 2 VLANs on the Dell switch, one for email subnet, one for DHCP subnet. Set 802.1q trunking between this Dell switch and the 3550 switch. Then create the 2 new VLANs on 3550 with VLAN interfaces and IP addresses as the default gateway for these servers.

Yes you are right Thanks lambent. You save me a lot of work.

I appreciate you help. Thanks again.
