2 layer 3 switch configs

[jclj]

Hi, we have two layer 3 switches in our environment. One of them does all of our routing and hosts all our vlans. The other is "suppose" to be used as a connected switch layer 2. When issuing the "sho ip route" command I see the following:

C       10.40.0.0 is directly connected, Vlan1

S*   0.0.0.0/0 [1/0] via 10.40.1.1

My understanding is this is another network. We have the same network on our switch that is used for routing. Would I need to issue the "no ip route" on the non routing switch?

Thanks

Hi Chris,

is the show ip route issued on "L2" switch?

C       10.40.0.0 is directly connected, Vlan1
S*   0.0.0.0/0 [1/0] via 10.40.1.1

Most likely, you have vlan1 configured with an IP address from that range. In addition, if you have an output like this, it means that you have ip routing enabled.

Therefore, I suggest to use the command :

Switch(config)#no ip routing

This will effectively turn your switch into "L2 mode".

Best regards,

Jan
