in a LAN environment that has many vlans from Access switches trunked to L3 switch, then from L3 switch the uplink port is connected to the router interface in order to route vlans to a different network.
how is the IP interface of the router facing those vlans going to be configured?
I have done similar configuration in the lab using router on a stick. But I have been told in the real world router on a stick is not used because of the performance sensitivity.
Any idea ?
