  • getting multiple subnets to work together

    hey ppl, I have several vlans configured on our Core 6509E switch. They are listed as example:

    interface Vlan175
    description Room 410
    ip address 172.16.x.x 255.255.252.0
    ip helper-address 172.16.20.5
    ip pim sparse-dense-mode

    They are now creating new ones with a 10.0.0.0/24 scheme. Now my question is can/will this new subnet be able to communicate with the existing network? All our servers/workstations are now using 172.16.x.x. Do I need to create access lists/route tables on the core after the scopes are created in DHCP? BTW, these new vlans were created to work with our new wireless network we setup through out our district. thanks for any feedback

    Yes it's possible.
    However you need a layer 3 device to route between those networks.
