Subnet Routing within one Vlan with Cisco 4908

Hallo everyone,
I have a little problem with our Cisco 4908!
We have oen VLAN (ID = 2) and within this VLAN we want to have some IP Ranges (192.168.2.0 and 192.168.3.0) each with subnet mask 255.255.255.0.
Is there any way that the 4908 takes over the routing between these IP Ranges?

Thanks a lot!

Two networks in one VLAN?

That's a straight layer three switch, so you'll have to use IRB (Integrated Routing & Bridging) with BVI's (Bridged Virtual Interfaces).



interface GigabitEthernet1
 no ip address
 bridge-group 2
 
interface GigabitEthernet2
 no ip address
 bridge-group 2
 
interface GigabitEthernet3
 no ip address
 bridge-group 2
 
interface BVI2
 ip address 192.168.2.1 255.255.255.0
 ip address 192.168.3.1 255.255.255.0 secondary
 
bridge 2 protocol ieee
 bridge 2 route ip

Each subnet should be in it's own VLAN.
Then you can configure inter-VLAN routing and ACLs.
