Cisco VLAN routing
Posted on 2014-08-09
Attached is a quick diagram of the network. Currently everything works fine, except the connection from the HP Switch in the 192.168.43.xx network to the 192.168.41.xx network. It doesn't work because the Cisco 3750 did not have the correct license to configure routing across vlans. We have installed the correct license now, but as soon as we enable IP routing on the 3750, the existing route (to the 192.168.1.xx) breaks.
the 3750 switch's gateway is the 192.168.41.1 firewall. workstations plugged into the switch can still access 192.168.1.x resources. however the switch itself cannot ping or be access from the 192.168.1.x network.
I can't see the problem enabling IP Routing would cause, but it's immediate. Remove IP Routing, and everything goes back to normal. I'm pretty sure enabling IP routing is the first step to configure a second vlan and routing to the HP (192.168.43.x) network.
