rageurdreams · ‎12-28-2007

Dear All,

I have WS-C3750G-24T-S L3 switch. I want to know whether i can configure OSPF in this switch or not.

Please provide me the help documents and commands to check this feature.

thanks in advance...

Hi,

First, the IOS should support L3. Use the IOS Feature Navigator to find the IOS that supports L3 and OSPF for the switch http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

Then the routing must be enabled. i.e.

!

ip routing

!

Dear Dandy,

Cisco IOS Software, C3750 Software (C3750-IPSERVICESK9-M), Version 12.2(35)SE2, RELEASE SOFTWARE (fc1<).

Is there any command to know compatability with OSPF.

Thanks.

hi,

please issue the sh version command, to find which ios version you are running and then use the cisco ios navigator tool to find the capabilities

regards,

shri.

Hi,

By default, your switch model WS-C3750G-24T-S does not support OSPF. The "S" in the model stands for "Standard Multilayer Image Software (SMI) " which means only RIP and Static Routing are supported. You need the model with an "E", i.e. WS-C3750G-24T-E, where "E" stands for "Enhanced Multilayer Image Software (EMI)" which supports Full Dynamic IP Routing (includes OSPF, BGP, etc..)

Check this link http://www.cisco.com/en/US/products/hw/switches/ps5023/ps5224/index.html

You can upgrade from SMI to EMI. IF you already upgraded, use the following commands in the global configuration mode.

ip routing

router ospf 1
