Routing 2 different ip segments

By sujeet ·
Hello !

We have CISCO 5500 switches at our location and 2 different ip segement with different subnets. like e.g. 130.123.186.xxx/24 and 130.152.178.xxx/25.
The subnets now communicate via router which takes more time than the switch to communicate.
What configuration changes should be done in the switch so that the routing is done from the switch itself. One switch has the route module also.

Thanks
Sujeet

Since you have the Router Module for InterVlan routing. I would recommand creating VLANS. A good place to look to see if this is a configuration for you is:

Good Luck.

I don't know which Supervisor card and Routing module do you have on your C5500, but try to look Cisco.com for MLS and CEF (Multi Layer Switching and Cisco Express Forwarding). This is "route once - switch many" features. What it does in general - it looks for traffic flow on L3 (router), creates "traffic flow pattern", and puts it down to L2 (switch). Theoretically, first packet from VLAN1 to VLAN2 will go through router, and all next packets will be just switched to correct port. Again, keywords "cef" and "mls".

Good luck.

Hi !
Thanks for your responses but the VLAN option is tricky as we have DHCP implemented and in case of VLAN ports on switch need to be fixed with one machine.
Now the solution found was to configure the primary and secondary in the router module of the switch itself and let this router talk to the external router.
This was done and it worked BUT still the problem of performance is there.
The throughput before implementing the solution was 3 Mbps and after implementing it is 20 Mbps but actual throughtput with the machines on the same ip segment is > 80 Mbps !!!
Any idea / solution what could be causing this problem in throughput ?

Thanks
Sujeet
