    Re: How to configure 2 HP 4108GL for IP routing with VLAN?

    After going through the issue of yours I am suspecting that default gateway is for the host of yours. because the host is able to see the Layer 2 and they are supposed to send L3 packets to gateway. If you have managed to change the default gateway to IP address on Switch A then the issue which you have mentioned over here would be resolved.

    Can you tell me switch which you are having the IP address assigned to VLAN? I think you will need to configure the static route which is outside of world through cli. That could be the reason you are getting the issue. as far as I know there would not be any need of configure the routes on the switch until and unless the default route on the non network traffic. The client computer will need switches IP for vlan for their gateway. Or other thing that you will require to add the route entry to send the traffic through the switch.

    You have to set up all the uplink ports and set to tagged for all the Vlans which you wanted to carry. After that every port should be assigned to vlan as that of untagged.
