5406zl strange inter-VLAN routing problem.

[Eby]

I'm having trouble with the 5406zl, i have created a new VLAN 50.

Now none of the hosts inside VLAN 50 will ping to hosts in VLAN 20 even with "IP Routing" enabled, but all can access Internet, which is VLAN 10 !!!!. Any idea what could be the problem ?.

Any help is appreciated.

Your networks are overlapping. You can't have 192.168/16 in vlan50 and 192.168.0/24 in vlan20 in the same time. I'm surprised it even let you configure it that way.

Sorry, It is a mistake I made while typing in the forum. The subnet mask is /24 for "LAB" VLAN, so there is no overlapping.

10.10.10.10 is the Firewall and there are no ACL anywhere in the switch.

Try taking out the ip default-gateway.

I remember this from somewhere else.  If you were not routing, then you would use the default-gateway command, but since you have IP routing and an ip route, you should not need the gateway command.
