5406zl strange inter-VLAN routing problem.
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 ?.
J8697A Configuration Editor; Created on release #K.14.41 hostname "Core Switch" time timezone 5 module 1 type J8706A module 2 type J9154A module 3 type J8706A ip default-gateway 10.10.10.10 ip ttl 32 ip routing vlan 1 name "DEFAULT_VLAN" untagged A8-A24,C1-C24 ip address 192.168.100.100 255.255.255.0 no untagged A1-A7,B1-B2 exit vlan 10 name "Internet" untagged A1,B1 ip address 10.10.10.1 255.255.255.0 exit vlan 20 name "LAN" untagged A2-A6,B2 ip address 192.168.0.1 255.255.255.0 ip igmp exit vlan 50 name "LAB" untagged A7 ip address 192.168.10.1 255.255.0.0 ip igmp exit ip route 0.0.0.0 0.0.0.0 10.10.10.10 snmp-server community "public" unrestricted spanning-tree no autorun password manager
Note. Default VLAN is not used.
Any help is appreciated.

Re: 5406zl strange inter-VLAN routing problem.
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.

Re: 5406zl strange inter-VLAN routing problem.
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.

Re: 5406zl strange inter-VLAN routing problem.
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.
