I have a limited understanding of layer 2 technologies but wanted to know the following.
I want to use a layer 3 loopback as a management port but I am unsure how that loopback can be used to communicate to upstream devices.
my initial thought was to put the loopback intoa vlan and some physical interfaces in the same vlan, but my understanding is that in order for that vlan to communicate to the next device that vlan would need to be passed through a trunk. is that accurate?
could I simply assign both physical interfaces into for example vlan 10 and expect it to work or do I need a trunk that passes that data through either side allowing the loopbacks to communicate.
