I currently have and X440 at one of my sites that I am creating a new VLAN to add in some additional IP's. I successfully did this at another site and it worked like a charm, but this one seems to not be cooperating. I have both rip and ipforwarding enabled on the Default and the new VLAN. The Default VLAN can ping the IP of the new VLAN and the new VLAN can ping the IP of the Default VLAN, but the new VLAN can't ping any devices on the old VLAN and the old VLAN can't ping any devices on the new VLAN.
I find it odd that the same config worked at another site, but doesn't on this one. The only difference from one site to another is the IP addresses used.
