Access a device connected in another switch.

[lautrec]

Hello everybody. How are you? 

Im little bit confused about one thing...i have theses two switches, 3 Com 4500 and 3 Com 2928, the printer is connected on the "2928". Each one working in your own subnet, 3Com 4500(20.20.0.X) and 3Com 2928(192.168.1.X).

I already tried to do a trunk and create a VLAN on the Switch 4500, configure a interface for the vlan and do the same on the switch 2928 except for the interface. But i dont know if the IP Routing is enabled or not.

I tried to make the trunk and do routes like:

3Com 4500: 20.20.0.0 255.255.240.0 192.168.100.1

3Com 2928: 192.168.100.0 255.255.255.0 20.20.0.1

But nothing of this resolve the problem. Someone can help me? Thanks in advance.

I dont know if this is good practice or not, but i did this way...

I create 2 Vlans in each switche

Switch A:

Vlan 255 - 10.5.0.1; 255.255.255.0

Vlan 100 - 192.168.100.2; 255.255.255.0

Swtich B:

Vlan 255 - 10.5.0.2; 255.255.255.0

Vlan 200 - 172.168.200.2; 255.255.255.0

So i create this routes:

Switch A:

10.5.0.1          -   255.255.255.     -    10.5.0.2

172.16.200.2   -   255.255.255.0   -   10.5.0.2

Switch B :

10.5.0.2          -   255.255.255.     -    10.5.0.1

192.168.100.2   -   255.255.255.0   -   10.5.0.1

Now the Switch A can ping i the switch and the vlans of the "B" and "vice versa". But i can't ping from Vlan 1 in any other vlan.

Hi,

Every subnet/VLAN needs a default gateway, since local clients can only ARP for local addresses.

If you have no default gateway on a host, it has no idea how to get to another subnet.

The switch's default gateway will be the address to which it forwards all packets with a destination it is unaware of (just like a host).

ARP if local, forward to gateway if not.

Command "ip default-gateway" on the access switches pointing to the core switch. Try this
