Hello,
We recently implemented a cat 4003 with 3 vlan config (Vlan 1, Vlan 2 and Vlan 3) with L3 configuration. The routing of these 3 vlan is via L3 software of Cat. 4003 L3 module. We used RIP as a routing protocol. Vlan 3 can not communicate through a Wide Area network but if u see on the routing table it is there" directly connected" but how come vlan can't communicate trhough a wide area network only vlan1 and vlan are able to see the WAN? What do you is the problem? Do i need to configure an static ip route for vlan 3 address? Hope to hear a word from u Asap...

Is there a network statement that would cover Vlan3 configured under ROUTER RIP? If not, it will not be advertised even if it is directly connected.
Also does Vlan3 have the same subnet mask as the interfcae over which it would be using to access the WAN? If it is not, this will cause a problem since RIP is a classfull protocol, meaning it does not send the subnet mask in routing updates but uses the subnet mask of the interface over which it learns the route.

Yes, there is. The 3 vlan's are configured under ROUTER RIP and vlan 3 is the same subnet mask /24 as with the WAN. I enter the console of cat 4003 and traceroute from vlan 3 to the DNS address which on the WAN, im having a problem on passing thru the router on WAN (next hop). What do you think would be a problem?

Could you go ahead and post the config of both the equipment. That could help a ton.
