how to do VLAN on cat3524?

[lordy]

I have a cisco switch 3524,and do VLAN on it.

vlan1:202.1.1.1--202.1.1.6 /255.255.255.248

vlan2:203.1.1.9--203.1.1.14 /255.255.255.248

vlan3:192.168.1.1--192.168.104.254 /255.255.255.0

cat3524 fa 0/1 port uplink to router2511 e0 port

vlan1 \

vlan2--cat3524--router2511

vlan3 /

On router,I have made static route about 203.1.1.8/29 and 192.168.1.0/24. And router E0 have a secondary IP address 203.1.1.14

Now only Vlan1 can access Internet through router,vlan2 and vlan3 can not do.On switch control mode,I enter command ping the IP in vlan2 and vlan3£¬but all the packets are lost.

I try to do trunking on switch fa 0/1 which uplink to router,and encapsulating ISL.Then all VLANs can not access Internet.

How to solve my problem?

thanks first!

sorry,I made a mistake in typing

vlan3:192.168.1.1--192.168.1.254/255.255.255.0

You need to use another router - 2511 doesn't provide ISL trunk feature. Generally, Cisco doesn't support VLAN trunks on 10Mbps router ports.

So use 2600 or some similar router and define trunk (ISL or 802.1q) on Ethernet port and on the switch uplink port. (If 802.1q be careful of native VLAN definition on the router port.) You will also have to define NAT for your VLAN3 (192.168.1.0 is in the private IP address range so it's unreachable from the Internet).

HTH,
