a simple question i guess..but need confirmation..we have configured vlans on my l3 switch and this is connected to a router. l3 switch is configured for ip routing.
Here are the below configurations.
For switch this is configured..
description TRANSIT VLAN
switchport access vlan 70
switchport mode access
ip address 10.191.28.8 255.255.255.240
This is fa0/3 port is connected to router with below config
ip address 10.191.28.2 255.255.255.240
no cdp enable
my question is, Is the transit vlan really required?shouldn't it be just like a normal "no switchport" in the switch fa0/3 with ip address configured??does the current config have any advantages..
The only real good reason I would use a transit VLAN would be for synamic routing - but I guess you could use it for anything you want.
If your situation - it does not really enhance your network. I would turn fa0/3 into a normal switch port - and let the router talk to the l3 interface in the switch.
