Me and my collegue were wondering about the following on a cisco 3750 x layer 3 switch.
Lets assume we configure the 3750 without vlans so we create several networks on the 3750. For example fa 0/1 has as network 10.10.10.0/24 with 10.10.10.1 as it being the default gateway. Fa 0/2 has as network 10.10.11.0/24 with 10.10.11.1 as it being the default gateway.
The question is if a broadcast storm rages on network 10.10.10.0/24, would 10.10.10.0/24 only be affected by the broadcast storm or will network 10.10.11.0/24 also be affected due the broadcast?
If we assume the same settings but we would utilize vlans then anetwork is definitely not being affected by a broadcast storm happening on an other network right?

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
