not communicating DLINK DIR 600 router with Cisco Switch

[najimap]

Dear Support,

last week i borught one  Dlink DIR 600 n 150 Router .through the Dlink router(Back to back connection)internet is working fine and wifi connection also.

my problem is:

my  current network is having 2 cisco switches and it is having defferent VLANs.

here i will i give all the current details with old internet router details.

Vlan 1:192.168.1.100(Default gateway) for DATA

Vlan 2:192.168.2.1(for Data and Avaya IP telephone).

Vlan 3:192.168.3.1(For Wifi Management)

Vlan 244:Router Gateway(192.168.244.1)

these  are configured in Cisco 3560 Switch.(VTP Server)

and the connection from the router (old internet gateway is Netgear dsl router)is directly connected to cisco 2960 Switch(VTP Client).this network is working fine.

now we purchased another isp and GPON Service and they provided (KEMS)Dlink DIR 600 Router.

for this we created one vlan (VLAN 4)and assign gateway as 192.168.4.1.One of the LAN port(LAN 1)is directly connected to switch 2960.but here we cannot get any reply from the clients.but we got reply from the switch 3560,while pinging to 192.168.4.1.

we put ip route 0.0.0.0 0.0.0.0 192.168.4.1 in the switch 3560 also.

still we are unable to get the whole network in service with new internet connection.

please provide  a solution for this problem.

awaiting for your  kind response.

Hi,

If Dlink in on VLAN 4 what ip address it has? Port connected to Dlink needs to configured as access vlan 4. Trunk between 2960 and 3560 need to allow VLAN 4. Clients on VLAN 1,2,3? You need to put reverse route on Dlink to VLAN 1,2,3 subnets.

Dear Abzal,

i have given vlan 4 ip as 192.168.4.252 and gateway ip as 192.168.4.1 in DLink DIR 600 router.i can ping from the switch 3560 to gateway.but when i connect the pc to the network ,no reply from 192.168.4.1.

the connection with 2960 and 3560 is a trunk port.

several forums are saying about reverse routing.

could you please give me a detail on this.

how can i make the connection ?

Note:the connection from the Dlink router is directly connected to cisco 2960.(the port in cisco 2960 is accessed as vlan 4)

Regards,

Najim.

Hi,

could you post a quick sketch of your topology because I don't clearly see how  the 3560 and 2960 fit in, it should be great too to give us the configs of both switches.

Regards.

Hi,

Correct if I'm wrong

Dir600 <-------> 2960 <--------> 3560

                        |

                     Hosts

?

Go DIR-600 configuration by using web browser 192.168.4.252.

Go advanced on menu items. Select routing.

Interface: Select interface that connected to 2960.

Destination: 192.168.1.0

Mask:

Gateway: 192.168.4.1

With other configuration same just change Destination network and mask.

Here is manual of Dir 600.

Hope it will help.

hi,

the diagram is correct,

But 192.168.4.1 is the ip of dlink router(to Browse the DLINK Router).and 192.168.4.252 is the vlan 4 ip configured in cisco 3560 switch.

here i will update the configuration what i'm going to do.

in the router -routing part:

1:Destination:192.168.1.0 mask 255.255.255.0 gateway 192.168.4.252

2:192.168.2.0 mask 255.255.255.0  Gateway 192.168.4.252

then

in the switch i will configure

ip route 0.0.0.0 0.0.0.0 192.168.4.1

is this configuration is correct?

Kindly requesting for your advice.

[Abzal]

Yes, you can configure like this. In this case all Internet trafic wil go through Dlink router. On 3560 it will be default route pointing Dlink and on Dlink it is reverse route to internal subnets.

Hi,

i have done the above configuration in the switch and router.i can able to get internet access only with vlan which is using for internet gateway.But when i browse from defferent vlan like 192.168.1.0 network i'm unable to get internet.

here i can post all the configuration i have done in the switch and router.

DIR Router 600 --------->Cisco 2960(port 6)---------->cisco 3560(Port 8 Trunk)

my vlans are

vlan 1 192.168.1.100 vlan ip for data

vlan 2 :192.168.2.1 vlan ip for data and avaya.

vlan 3 :192.168.3.1 vlan ip for wifi management.

vlan 11:192.168.11.2 vlan ip for New internet gateway.

in the 3560 ,it is the vtp server.

we have different ip dhcp services.

ip dhcp pool data

network 192.168.1.0 255.255.255.0

default router 192.168.1.100

dns server x.x.x.x

ip dhcp pool dataavaya

192.168.2.0 255.255.255.0

default router 192.168.2.1

dns server x.x.x.x

ip dhcp pool kems (vlan 11)

network 192.168.11.0 255.255.255.0

default router 192.168.11.1

dns server x.x.x.x

ip route 0.0.0.0 0.0.0.0 192.168.11.2

from the switch when i use vlan 11 directly i can get internet.

but if i use vlan 1 or vlan 2 i'm unable to get internet.even i cannot ping 192.168.11.1 .but i can ping to 192.168.11.2 gets reply from this vlan ip.

in the Dlink router i use routing part what you have suggest me.

interface      Destiantion     Subnetmask      Gateway  

Public ip     192.168.1.0     255.255.255.0   192.168.11.2

Public ip     192.168.2.0     255.255.255.0   192.168.11.2

Still i cannot get internet.

what could be the reason?

One cisco engineer is saying that ISP has to do some nating from their side for multiple vlans to communicate.

do you have any idea about this.,then i can directly contact with isp if i have some information.

awaiting for your kind reply.

Thanks and regards,

Najim.

Hi Najim,

I see, can you tell me on which VLAN Dlink resides and it's IP address? Also I need to know SVI's IP address of that VLAN on 3560(VLAN connected to Dlink) Then I can help you much better.

Hi Abzal,

here dlink is on vlan 11. and 192.168.11.1 is the ip address of Dlink router.192.168.11.2 is the vlan 11 ip address configured  in the 3560 switch.

Najim.

[Abzal]

Ok, then you need to change ip route on 3560:

ip route 0.0.0.0 0.0.0.0 192.168.11.1

And port connected to Dlink should be on VLAN 11.

Dlink is configured properly. Then try to ping 192.168.11.1 from hosts.
Try this and let me know.

Abzal,

here i already configured the same ip route.,by mistake i typed it wrong in my previous comments.

the port which is connected to dlink is vlan 11.

i can ping to 192.168.11.2 from all hosts,but still i cannot ping to 192.168.11.1

this is happening when i connect with deffrent vlan only.

from the same vlan (vlan 11) internet is working fine.

still issues not resolved.

regards,

Najim.

It seems Dlink 600 does not support static routing over LAN port only WAN port.
Am I right? When you were configuring static routes could you be able select LAN port instead of WAN port?

so here ow i will use ip route?

ip route 0.0.0.0 0.0.0.0 x.x.x.x (here x.x.x.x) is the public ip instead of using 192.168.11.1.

do i try this way??

pls give me breif explanation if i'm wrong?

najim.

[Abzal]

This will not change anything because when traffic goes from 3560 to Dlink, dlink does not know how to route back to 3560. Instead Dlink routes packets to WAN interface. But it should be LAN where 3560 connected.
I found forum one thread and apparently this Dlink is designed for home users or small office with one LAN subnet not anymore. So that's why you are able to access to the Internet from VLAN 11.
