Can someone please advised me on the most suitable method for inter vlan routing with the following setup:
---- [External IP 1841 Internal IP] ----- [Vlan 10 on a port of a Catalyst3750 (AKA Core)]
The Cisco 1841 router has 2 interfaces internal and external. The internal is connected to a port on the switch that is configured on VLAN 10, the management vlan for the switches is running on VLAN1. there is no trunking currently between the router and switch, only between the 3750 and the rest of the Cisco switches connected to it.
Should I trunk from the router to the switch create sub interfaces on the router or create vlans on the switch turn on ip routing and run a routing protocol between the switch and router. I guess I'd have to turn the switch port connected to the router into a routed switch port?
