Cisco 3550 InterVlan Routing Problem 1

[jacob200]

I need some help!! I've got a 3550-24 EMI switch. I have two vlans on it and they are configured as 192.168.1.50 (vlan 10) and 192.168.20.50 (vlan 3). I also have a laptop hanging off each end. I cannot get the laptops to ping each other. I do have the "ip routing" command enabled on the switch. Also each laptop can ping the vlan interface which is their default gateway. Also, the "sh ip route" command looks good too. Any suggestions on how to solve this problem would be highly appreciated.
Thank you,

Could you post the config?

Here is the config for the switch.

Post a "show ip route" to see if it is showing the routes in tis database. You may also need to enable RIP so that the routes are shared.

 

[BuckWeet]

You don't need RIP to distribute routes when the interfaces are local to the box..

 

[lui3]

have you added the vlans in the vlan database

command is

vlan database
vlan 10
vlan 30

then exit
exit
show vlan

 

[BuckWeet]

vlans automatically get created once they're assigned, unless its in vtp client mode.. and the fact that he said he could ping the L3 vlan interface from the laptop that is sitting on that VLAN, that rules out the fact that the VLANs are created.

 

[lui3]

check the default gateways and subnet masks on the laptops. what does a trace route from the pc tell you. how about debug icmp on the router. what does it say?

 

[Parcival21]

well I'm a total newbie. But don't you need to declare the routes between the different vlan's? I didn't see it in the config. Or enable a routing protocol as rburke said?

 

[BuckWeet]

No, this is a layer 3 switch, just like a router.. It sees those subnets as being directly connected, therefore no need to have routes or routing protocols running..

See this link.

Just for laughs can you try adding the vlan database information as stated above.

It can't hurt.

Hello
I need some help...
I have to configure 3 Vlan (3 class C IP on each) ( Vlan 1 Management) on 2 6509 and 4 3550 catalyst, I need to route this classes on one PIX right now configured.
Anyone has a draft on how make this vlans ( I have right now the VTP on one 6509) and configure an InterVlan for the pix (??)

THanks a lot !!
