I'm relatively new to the Adtran world so bare with me if I ask stupid questions.
My client wants to set up WAN failover on their Netvanta 3430. I noticed that this model only have Eth 0/1 and Eth 0/2. Eth 0/1 to for LAN and Eth 0/2 is for the primary WAN. They used to use PRI for their PBX but not anymore.
I'm wondering if we can set up the primary WAN and secondary WAN on the same interface - Eth 0/2.
If this is possible, please let me know and show me how to configure it. Thanks in advance!
