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 ( and each with subnet mask
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
 ip address secondary
bridge 2 protocol ieee
 bridge 2 route ip

Open in new window

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