We have a router, f0/0 will be for the Internet connection with bandwidth of 30Mbps.
Its f0/1 will be connected to a switch for internal networks.
This link will be separated to 3 VLANs for 3 internal networks.
Is there is a way to guarantee 10Mbps for each VLAN but allow use up to 30Mbps when another two VLANs are not using any Internet...
