i would like to configure intervlan. i thought for good understanding i would go for router on stick model.
i have few questions:
1. if i configure 4 vlans on different subnet. then is it necessary to configure routing on router as they on different networks.
2. trunk port carrys all vlan information, so then all vlans will be able to communication, then how would i restrict them. (i mean vlan2 will communicate with vlan3 and not with vlan 4,5..)
