Routing between Subnets on HP Procurve 2650
Hi, i am trying to add another subnet to our network.
the existing network is 192.168.16.0/24 and i am trying to have 192.168.16.246 to "point" towards the 15subnet (i am running out of 16 subnet ip addresses.
trying to add a subnet of 192.168.15.0/24 using a vlan on a HP Procurve 2650.
i have setup a vlan for the 15 and 16 subnets and switched ip routing on.
on the 2650 switch i have port 1 15.0/24 DHCP device, i want to introduce the 16 subnet on port 2 with the rest of the switch being the 15 subnet.
i can ping devices in each subnet when i have an ip of the specific subnet but i cannot ping/view devices in the other subnet.
what do i need to do to be able to see/ping devices in both subnets?
config i have so far:
hostname "15SUBNET SWITCH"
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
no ip address
no untagged 1-50
exit
vlan 15
name "15SUBNET"
untagged 1,3-50
ip address 192.168.15.3 255.255.255.0
ip helper-address 192.168.15.1
ip igmp
exit
vlan 16
name "16SUBNET"
untagged 2
ip address 192.168.16.246 255.255.255.0
ip igmp
exit
thanks in advance!

Now Clients should have IP of vlan as dgw : 192.168.15.3 in vlan15 and 192.168.16.246 in vlan16.
Next you will need ip helper-address 192.168.15.1 in vlan16, if that is to act as DHCP-server for 192.168.16.0-network.
If clients are to go to internet you wil need a dgw on this switch like: 0.0.0.0 0.0.0.0 192.168.0.1 (or whatever) and some routes back on the 192.168.0.1 to 192.168.15.0 and 192.168.16.0.

ok - the 16 subnet already exists and they get their IP from existing dhcp routers/servers.
what i am trying to do is add the 15 subnet to it and have the 15 and 16 subnet communicating on all 15 and 16 ip's.
i have set the dgw on the 15subnet to be the ip address of the vlan, and this can now see the ip address of the 16 subnet, but cannot see any devices on the 16 subnet.

what i think i'd need to do in as far as the 16subnet side is put a static route of:
192.168.15.0/24 192.168.16.246
so that the traffic in 16 knows where to send the traffic if it needs to communicate with the 15subnet but still doesn't let me ping anything in the 15 to the 16 or the 16 to the 15 subnet.
192.168.15.0/24 192.168.16.246

If you have
Ip routing
then 192.168.15.0/24 192.168.16.246 is added automatically
show ip route
should display

if i actually try to add the route "192.168.15.0/24 192.168.16.246" it says "192.168.16.246 can not be switch IP address and route gateway at the same time."

my IP settings:
IP Routing : Enabled
Default TTL : 64
Arp Age : 20
VLAN | IP Config IP Address Subnet Mask Proxy ARP
------------ + ---------- --------------- --------------- ---------
DEFAULT_VLAN | Disabled
15SUBNET | Manual 192.168.15.246 255.255.255.0 No
16SUBNET | Manual 192.168.16.246 255.255.255.0 No
( since first posting i have changed the ip of 15 sub to match the 246 of the 16 subnet and cascaded these changes from 15.3 to 15.246 where required.

weirdly i can ping using the switch console to devices on either subnet:
15SUBNET SWITCH# ping 192.168.16.2
192.168.16.2 is alive, time = 1 ms
15SUBNET SWITCH# ping 192.168.15.52
192.168.15.52 is alive, time = 1 ms
15SUBNET SWITCH# ping 192.168.16.2
192.168.16.2 is alive, time = 1 ms
15SUBNET SWITCH# ping 192.168.15.52
192.168.15.52 is alive, time = 1 ms
did you try add a dummy IP to vlan1 , like 192.168.168.1 255.255.255.0

ok so i have 2 laptops
one as: 192.168.15.52/24
one as: 192.168.16.2/24
i cannot ping one laptop from the other.. is this what you are wondering?

and they reply ping in own range?
ASKER
yes if in own range they ping each other ok - i had previously tested this to make sure the windows firewalls were letting ping through :)

thanks - i went into advanced firewall and set the icmp on ip4 (in and out) to "all" networks, not just "work" and i can now access the devices!
awesome help jburgaard, many thanks!
