L3 switch routing question

Hi all,

I have a Catalyst 3550-SMI and I want to use it to perform Layer 3 routing to separate two private networks 192.168.1.x/24 and 192.168.2.x/24.

Router f0/1(192.168.1.1/24)<-> catalyst3550 f0/1(192.168.1.254/24)

catalyst3550 f0/2 (192.168.2.1/24) <-> client (192.168.2.2./24)

I have enabled ip routing so show ip route will display both network in its ports, and enabled L3 switch function. I am able to ping both router ip addr eth0 (192.168.1.1/24) and client pc (192.168.2.2/24) only from this switch.

But the client and the router are not able to ping each other.

I want to use 192.168.1.1 is the only way out from both of networks to the internet. Any helps and suggestions will be greatly appreciated.

Thank you very much.

Just to check, did you try setting the default gateway of the client to 192.168.2.1? Also, the router (192.168.1.1) should see a route to 192.168.2.0/24 with a next hop of 192.168.1.254.

Hi all, thank you for the advices. Sorry after a week long (sick leave).

I think I forgot to add static route for 192.168.2.x through the same interface as 192.168.1.x. Now it's working properly, thanks a lot.

Best regards,

Hi,

I think you made a typo, but you do have 3550 -EMI, not 3550-SMI?
