cannot route between 2 HP v1910 switches

Hi people
I really need your help here, I am trying to route traffic between 3 sites, this is a simple config, but it has got me beat. I am trying to route traffic between 3 sites, site A is the hub and site B and C are satellite offices.
Site B and C never need to see each other so I just need site A to be able to see both B and C and the  satellite sites see site A.
I am using 3 HP V1910 Switches to do the routing and on each switch, I have created port 1 to 8 as VLAN 1 on the 10.x.x.x network and port 9 to 16 on VLAN 2 on the 172.1.1.x network. I have two VLAN interfaces configured on all switches so for example site A is 10.11.11.1 and 172.1.1.1
I have added a static route on each router with the next hop as the 172.1.1.x address but when I try to ping the device at the other end, I do not get a reply. I then added my laptop to the 172.1.1.x network (which is 24bit by the way) I cannot ping any of the 172.1.1.x addresses however if I ping a 172.1.1.x address from the DMZ side of 10.11.11.x I can ping the local router address but not the next hop, this is urgent as I have to get this working for a customer by lunchtime Wednesday and I am new to routing using HP switches, so any help even a script would be really helpful.

Post the configs of the switches please.

how do I do that as as I have done all the configs using the gui?

I think from the GUI:

Device -> Configuration -> Backup

Then save it as a ".cfg" file.

That should be a readable text file. Upload that.

Did you enable inter vlan routing on HP switches.  It's been a while for me, so my question is how does traffic go from VLAN1 to VLAN2?  Etherflow VLAN appears to be the same subnet 172.1.1.x, so what's the default gateway for VLAN1 (If any)?  I would first start to get get 172.1.1.x to work.  Site B and C can't both be going into port 15 of A.  Did you setup HP's in a lab before deployment?  How are you communicating to HP switches if you can't ping?  Also, is Etherflow just a long-distance Ethernet solution?

Hi donjohnston, I will upload the config in the morning when I am back in the office.
Fizicist, the traffic works between vlan 1 and vlan2 works  no problem. From my laptop, I can ping both interfaces from the 10.11.11.0 network. Vlan1 is the default gateway and the address is 10.11.11.1 (site A) the diagram doesnt really show the setup clearly but the etherflow is is as you stated a long distant ethernet so all three switches are connected together via port 15. this is the first time that I am setting up HP switches and currently the switches are in our lab.

How are you connecting 2 cat5 ethernet cables to 1 port?
This is what your describing...
Site B Port 15 < ---- > Site A Port 15
Site C Port 15 < ---- > Site A Port 15
I'll take a guess and say Site A is using 15 & 16.
If I was going to debug, I'd place my laptop on Site B and give it an address.
Lets say 172.1.1.4 since 1 - 3 are switches.
My laptop now needs a default gateway address, lets say 172.1.1.1  Gateway has to be on the same subnet, else the system has no way of knowing how to get to it.
I should be able to ping any switch if static routes don't get int the way.
That should take care of 172.1.1.x network.  How does my machine now know how to get to 10.x.x.x networks? Also, what is the default gateway for 10.x.x.x.  I'd guess it's the VLAN1 IP of the HP's.
Site A needs a static route for Site B.  You'd have to tell the HP (Site A) that 10.12.12.x is reachable via 172.1.1.2.  Site B should by default be pointing to 172.1.1.1.
I think of a relay race when mapping out routes.  Each machine needs to know who to hand the packet off too.  A computer on 10.12.12.x (Site B)  needs to use 10.12.12.1 as it's default gateway.
Site B HP has it's default route which should be 172.1.1.1  So a computer in VLAN1 says I need to talk to 10.11.11.x, I first had off packet to HP on 10.12.12.1, it says 10.11.11.x doesn't belong to me, so I'm going to give it to default at 172.1.1.1.  172.1.1.1 says, I know who 10.11.11.x is, it's on my other interface and sends it to the user computer.  The return gets tricky. 10.11.11.x is using 10.11.11.1 as it's default gateway.  Site A HP needs to know where 10.12.12.x and 10.13.13.x or it sends the traffic out Site A default gateway (which let's say is the internet and then gets lost).
So Site A needs to know how to reach the other 10 networks.  So you say, if it's 10.12.12.x, then go to 172.1.1.2 first, if it's 10.13.13.x, then go to 172.1.1.3 first.

I wrote it out so you get into the idea of how packets traverse a network.  Remember that each device will have a default gateway that will receive all packets for any network it doesn't have a record for.  It could be that A is using B as a default and B is using C as default and C is using A as default.  I doubt this would work at all.
If you can add default gateway info, maybe I can find where you're getting stuck.

Hi Fizicist
using site A as an example, the switch is split into 2 vlan's, port 1 to 8 is vlan1 with a subnet of 10.11.11.0, the vlan interface which s also my gateway for my laptop is 10.11.11.1 and i have a cable connected to port 1.
vlan 2 is port 9 to 16 and port 15 is where the cable plugs into the etherflow. the address on the vlan interface is 172.1.1.1 the routing you described above is essentially what I have. i have a route that states 10.12.12.0 mask 255.255.255.0 next hop 172.1.1.2 via interface vlan2. which doesnt work, when I plugged my laptop into the 172 subnet and as you stated above give myself 172.1.1.5 address and use site a as my gateway, I cannot ping any of the 172.1.1.x interfaces which I dont understand, but when i give my laptop a 10.11.11.5 address and a gateway of 10.11.11.1, not only can I ping the 10.11.11.1 gateway I can also ping the 172.1.1.1 address as well. which is what I would expect so why can I not ping any of the 172.1.1.x addresses when I am sitting on the same subnet?

I just quickly went through the HP manual for the switch.  The manual seems to indicate that the VLAN's need to be tagged in order to go through the trunk ports.
Look at
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c02965327/c02965327.pdf
Start at page 143.  It'll give you an example via the GUI how to setup trunk ports on the HP.  I don't have experience with HP 1910's, so I can't help further.

I actually did this today but still no joy, the problem seems to be on the 172.1.1.x side of the network, once i can ping that side, I think the routing will kick in

Craig BeckCommented:
You don't need to trunk anything on the EtherFlow links as they are effectively routed links.

Pinging the 172.1.1.x IP addresses will be a problem unless you add a default gateway to the switches (NOT a default route)



Configure the following on Switch A...

ip route-static 10.12.12.0 255.255.255.0 Vlan-interface2 172.1.1.2
ip route-static 10.13.13.0 255.255.255.0 Vlan-interface2 172.1.1.3



Configure the following on Switch B...

ip route-static 0.0.0.0 0.0.0.0 Vlan-interface2 172.1.1.1


Configure the following on Switch C...

ip route-static 0.0.0.0 0.0.0.0 Vlan-interface2 172.1.1.1




You should ensure that:

Clients on the 10.11.11.0/24 network use 10.11.11.1 as their default gateway.
Clients on the 10.12.12.0/24 network use 10.12.12.1 as their default gateway.
Clients on the 10.13.13.0/24 network use 10.13.13.1 as their default gateway.

How do I add a default gateway to the 172.1.1.x interface? and can this be done in the GUI or does it need to be via CLI?
0
Craig BeckCommented:
You add a default gateway to the switch itself - it is different to adding a route.
The default gateway directs traffic from the switch itself, whilst the static or default route directs traffic from clients.

is there a proceedure on how to do this? sorry I am new to these switches and the manual isnt very clear

I have now resolved this issue, the problem was caused by a switch other than the ones I was trying to configure, once I removed the ofending switch the HP's came to life
