We have a few locations that have switches passing 802.1q trunks between them via radio links. These radios will also allow VLAN tagging of data on it’s Ethernet port, and has an internal serial port that acts as a terminal server that can be programmed to a specific VLAN.
This is useful if you have one end node that needs to be on a specific VLAN, or if you have serial data that needs to placed on a particular VLAN. The radio has a management IP that can be set to the native VLAN, and you can assign an IP that resides upon another VLAN (for access to the serial ports).
My question resides around routing data to the radio when there are two IP addresses from different subnets assigned.
For example, the management IP address of the radio would be 10.0.1.99 and reside on the native VLAN. The other IP address would be10.0.2.99, and resides on the terminal server VLAN (VLAN-2).
We seem to be getting some conflicts when we try to communicate to the radios management IP address, when passing data to the terminal server IP address on the second VLAN. We looked at the router and the ARP table shows the two IP address with the same MAC address (same device, two IP addresses).
We are an OSPF network. I come from an EIGRP world and barely qualify for CCNA.
Could this be causing the conflict?
Is there an easy way to resolve this with a statement in the router that will not conflict with other operations?
