I have a lab network with 7 different networks. The current configuration has each network switch (CISCO 3750G) connect to a core switch (CISCO 3750G) which in turn is connected to an Engineering Router, a test router, and a home router. Information currently flows properly over all links.
We use vlans 10 from the networks to the core. From there, the links to the routers are trunked and new vlans are assigned to each network within the trunk. For example, one network uses vlan 10 to get to the switch, then uses vlan 6 to travel to its router interface through the trunk. The router interface is using dot1q 6 on interface fa0/0.6.
My question is, should we, or can we use trunking from the network switch. If so, can we use a native vlan of 7 and achieve the same result?
