L3 Inter-VLAN Routing
This should be a simple one. I have a 3750 setup as a L3 switch. I have two VLANs.
VLAN 20 and 132.
While logged into the switch I can ping devices on VLAN 20 and VLAN 132. From a computer on VLAN 132, I cannot ping a computer on VLAN 20 and vice versa.
A computer on VLAN 132 can ping the VLAN 20 gateway 192.168.90.254.
A computer on VLAN 20 can ping the VLAN 132 gateway 172.16.132.9.
What am I missing here?
