svi on 2960S

I am working on a Catalyst 2960S and I see 3 SVIs being assigned to the switch. I can also ping to those SVI. I am confused as the 2960S does not do layer3. How will this all work? Thanks

They support static routing but not routing protocols.

So does it mean that the 2960S can do inter-vlan routing then?

This is a partial configuration:

interface vlan1
ip address 10.10.1.15 255.255.255.0
!
interface vlan10
ip address 10.10.10.1 255.255.255.0
!
interface vlan20
ip address 10.10.20.1 255.255.255.0
!
ip default gateway 192.168.1.1

Yes, you can do intervlan routing on that switch. Make sure you do:

conf t

ip routing (enables routing)

ip route 0.0.0.0 0.0.0.0 192.168.1.1
no default gateway 192.168.1.1

Assign specific ports to the desire vlans and point the hosts connected to the said port to the vlan interface as its gateway and ip address on the same subnet.

Soulja is correct.
They do intervlan routing with static addressing.  VLANs are automatically known and shown as directly connected.  The ip route 0.0.0.0 0.0.0.0 192.168.1.1 should show up as S.
You could route traffic somewhere else too, so long as you use ip route.

The gateway for the clients is different than the 0.0.0.0 route for the switch.
The ip address for a client in your vlan10 example might be:
ip:  10.10.10.100
snm:  255.255.255.0
gateway:  10.10.10.1

I am so confused. I thought that the 2960 cannot do layer3.

The 2960s supports very limited layer 3 functions.  Static routing, and very limited number of static routes at that.  No one would buy one thinking they were getting a layer 3 switch.
The 2960-XR has even more layer 3 features, but still less than IP LAN Base software.

Cisco added limited L3 function with IOS 12.2(55)SE.  I think up to 8 SVI's and static routing only.

Where can I find documentation that says it supports SVIs. I checked the Cisco website but could not find it. Thx

Also remember to change the SDM template to lanbase-routing (or whatever it calls it in your version of IOS).
