I have a VLAN routing issue on our network. We have two ProCurve 5406zl's being used as our core switches, each vlan on these switches has an IP address and VRRP is configured on each vlan for redundancy. I have enabled IP routing and Inter VLAN routing is working to some degree but not fully.

Testing with some devices connected to the same core switch I was able to ping a device on vlan 30 from all other vlans. But the device on vlan 30 is unable to ping devices on the other vlans.

Below are my test results.

JW3-CAB02-CORE02# ping 10.10.20.2 10.10.20.2 is alive, time = 14 ms JW3-CAB02-CORE02# ping 10.10.20.2 source 10 Request timed out. JW3-CAB02-CORE02# ping 10.10.20.2 source 20 Request timed out. JW3-CAB02-CORE02# ping 10.10.20.2 source 30 Request timed out. JW3-CAB02-CORE02# ping 10.10.20.2 source 40 10.10.20.2 is alive, time = 1 ms JW3-CAB02-CORE02# ping 10.10.20.2 source 50 Request timed out. JW3-CAB02-CORE02# ping 10.30.33.41 10.30.33.41 is alive, time = 1 ms JW3-CAB02-CORE02# ping 10.30.33.41 source 10 10.30.33.41 is alive, time = 1 ms JW3-CAB02-CORE02# ping 10.30.33.41 source 20 10.30.33.41 is alive, time = 1 ms JW3-CAB02-CORE02# ping 10.30.33.41 source 30 10.30.33.41 is alive, time = 1 ms JW3-CAB02-CORE02# ping 10.30.33.41 source 40 10.30.33.41 is alive, time = 1 ms JW3-CAB02-CORE02# ping 10.30.33.41 source 50 10.30.33.41 is alive, time = 1 ms

Here are the two devices showing in the ARP cache table

Here are the important bits of the switch configuration

So it looks like this is working now, in the end the particular devices I was pinging didn't have the right default gateway and/or subnet mask setup by the equipment installers.

I incorrectly assumed that if the switch could ping them then it was good enough and the device should be able to ping other subnets but it doesn't look like this is the case.
