Just want the advise, can multiple vlans belongs to one large subnet. For example Vlan 2 to Vlan 30, network 172.16.0.0/16 ( All hosts on vlan 2 to vlan 30 will have the IP addresses from that range).
Vlans hosts only need DHCP assigned addressess and internet access. No inter-vlan routing is required but hosts within a vlan should be able to talk to each other.
Is that a better design to have a DHCP Pool created for each Vlan (so 30 DHCP Pools) on Cisco 3550 switches or just a one DHCP pool would do the job. I have around 300 hosts on network divided on 30 vlans which spread over on four Cisco 3550 switches.
Would there be a network performance issuess such as large amount to broadcast and slow response time ?. According to my understanding there will be a broadcast domain for each vlan so network performace should not be effected ?
Thanks for the help.
