Question about Vlan connection in Layer 2 switch

Any expert can explain the vlan routing to me?

Here is topology: PC3 ------ SW1-----PC5. The switch (SW1) is layer 2 switch which connect PC3 and PC5, which are assigned to two vlan, vlan 13 and vlan 15, respectively. At SW1, I created SVI and configured vlan 13 and vlan 15, which are assigned to the SW1 port. The question is that PC3 and PC5 are in different vlan in the Layer 2 switch, why the two PC can ping each other ? Thank you.

Can you better explain this part. You lost me here. If you have each computer is assigned to a different vlan, they should not be able to ping each other.

Can you post the switch config?

interface Vlan50
 ip address 15.0.0.1 255.255.255.0
!



SW1#sh ip int bri

Which model switch is this? Are you sure it's in layer 2 mode only.

Enter sh ip route to confirm.

SW1#sh ip route

Gateway of last resort is not set

     13.0.0.0/24 is subnetted, 1 subnets
C       13.0.0.0 is directly connected, Vlan30
     15.0.0.0/24 is subnetted, 1 subnets
C       15.0.0.0 is directly connected, Vlan50

I think this is a reason


Thank you

You probably already know, but just in case:

no ip routing


to disable layer 3 mode.
