Scenario : Few pc on a LAN subnet and few others on a different LAN subnet
All are tepmorarily connected to a single ethernet switch (no VLAN capable) waiting for a second dedicated switch to arrive.
Two ports of this single switch are connected to eth1 and eth2 of a routerboard, these ports have different ip class and are configured as default gateway for each of two lan subnet,
Running torch on each RB ports I see all broadcast and multicast packet coming from both the subnets (also the unwanted one)
Could this bring to particular problems (traffic issue, etc.)??
Can I avoid unwanted subnet packets to be processed by each of RB ethernet ?
