SWITCH_L3 › CONSOLE LOGS ● IP ROUTING OFF
System ready. SW1 is a multilayer switch with two SVIs acting as default gateways for VLAN 10 and VLAN 20. IP routing is off, so the SVIs exist but SW1 does not forward IP traffic between VLANs.
Routing Table (FIB) SW1 RAM 
SW1# show ip route
IP routing is disabled.
SVIs can still be used for local management,
but SW1 is not L3-forwarding between VLANs.
