Removal of ip route command

         Hi all,

Need to confirm Network config below

We  have client where they are using layer 3 switch with no ip routing enabled.

It has default-gateway  command configured.

Need to confirm that ip route command is used for layer 3 switch only and it switch is used as layer 2 only it is ok to be removed?

Thanks

Mahesh

Hi Mahesh,

Yes, if the switch is layer-2 only, you don't need the IP routing command, you just need the ip default-gateway command.

Mahesh,

Running default-gateway is OK.

Example

!

no ip routing

!

interface vlan 555

description *** Management Vlan **

ip address 10.5.5.5 255.255.255.0

no shut

!

ip default-gateway 10.5.5.254

!

So basically the ip address 10.5.5.5 is just for managing the swtch.

The switch is only carrying out layer 2 functions
