HP 5406 L3 VLAN Routing

[ITGURU]

Hi,

Looking for some help on HP Switches and Core switch 5406 inter-vlan routing.

 

On D-Link switches, i added a new VLAN (40) to a core switch, added an IP interface to the VLAN. On a client I can set a static IP using the core switch as the default gateway IP address and I can ping from the client to both the VLAN 1 and other VLAN (40) on a different IP range and also access the internet using it as the gateway.

 

On the HP 5406 I have added a new VLAN (40), and assigned an IP to it

When i add static ip address to client and use the HP as default gateway I cannot ping the newly added VLAN IP address interface or gain internet access using it as a gateway.

 

What am i missing on the HP?

 

Thanks.

I have half resolved this - Routing was not enabled on the switch so i can now ping the second VLAN's interface IP address, however i cannot access the internet.

The PC is configured on VLAN 1 , same as the lightspeed box - if i specify the proxy IP on vlan 1 in IE then it works, but normally i just have to open IE and with auto detect selected i can gain access.

 

On the HP core switch it's default gateway address is that of the site's internet router, same as any DHCP assigned address.

 

Any advice why it won't auto detect the proxy when using the core switch as the gateway ?

Once you've enabled routing you'll need to add a 0.0.0.0 route to your lightspeed box for the internet. The default gateway setting no longer takes affect once routing is enabled.

 

ip route 0.0.0.0 0.0.0.0 x.x.x.x (where x.x.x.x is the IP of your lightspeed box) should be what you need. For neatness though (in terms of making the config look tidier) turn off routing, remove the default gateway, turn routing back on otherwise it remains in the config doing nothing.

Thanks - this is the route to add to the HP Core switch? Even though specifying the proxy address works, but auto config doesn't?
