Powerconnect 62xx Routing capability

I apologize for the subject not being very descriptive.  I can't find a place to edit this.

Yes, the PowerConnect has several Routing Protocols built into it, which makes it capable of routing between subnets.

We have set up 2 vlans on seperate networks at this point and they are not talking.  I was under the impression that these should be talking without setting up any special routes at this point.  Is this incorrect?

You have to configure the switch to route between the VLANs.  It doesn't do it automatically.  Many administrators wouldn't want that to happen automatically.  Here's an example of how I configured my PC6248 to route between two VLANs.  I've got it configured to route between VLAN 2 and 3.

Thank you!

 

Subnets are talking now thanks to you, but our gateway is on vlan2 and this is fine for vlan2 computers (they can access the internet fine).   However vlan3 PC's can only ping Vlan2 PC's, but not the gateway on vlan2.

 

gateway is 75.40.196.6

Any thoughts on what we may be missing?

 

Here is the config if this helps

What do you have as the default gaeway for the clients in VLAN3?

 

 

The Vlan interface IP.  Those machines can ping across the VLAN they just can not get out of the gateway.

From a system on VLAN2, can you ping the VLAN3 IP interface (VLAN3 gateway)?

 

That is correct.  We can ping across subnets at this point. 

 

Vlan 2 can ping the gateway and get out to the internet.

Vlan 2 can also ping PC's on Vlan 3

 

Vlan 3 can not ping the gateway and can not access the internet.

However Vlan 3 can ping Vlan2 interface and PC's on Vlan2.

This is the output of show ip route

S      0.0.0.0/0 [1/0] via 75.40.196.6,   vlan 2
C      75.40.187.0/24 [0/0] directly connected,   vlan 3
C      75.40.196.0/29 [0/0] directly connected,   vlan 2

And your gateway to get to the internet is 75.40.196.6?

Yes that is correct.

 

Can you give me the output for "show ip route" at the EXEC level on your switch?  I want to see if the switch is recognizing "ip route 0.0.0.0 0.0.0.0 75.40.196.6".

On the clients that are connected to VLAN2, what do you have set as the default gateway?

 

On the clients that are connected to VLAN3, what do you have set as the default gateway?

 

Right now I think that the solution will be to set the default gateway on the VLAN3 client to 75.40.196.6.  Communications to VLAN2 clients from VLAN3 clients should still be picked up because ARP requests will be forwarded by the switch to VLAN2 (since routing is enabled on the switch).  Try changing the default gateway on one of the VLAN3 clients.  Then on that same client, try to access the internet, then try to ping a system on VLAN2.

I appreciate your help - thank you again.

I'm missing something rather simple I'm sure.

 

S      0.0.0.0/0 [1/0] via 75.40.196.6,   vlan 2
C      75.40.187.0/24 [0/0] directly connected,   vlan 3
C      75.40.196.0/29 [0/0] directly connected,   vlan 2

 

Clients on Vlan2 use .6 for the gateway

Clients on Vlan3 use the interface IP as the gateway.

 

I have changed the vlan3 client to use the .6 gateway with no luck.  I could still ping across the subnets but still could not get a ping reply from the gateway to those pc's.
