Hi, good morning. My name is David, I'm new to this forum and I'm from Córdoba, Argentina.

I want to know how this router works with these two options simultaneously. I actually have 4 internet connections with Bandwidth Based Balance Routing and Application Optimized Routing enabled. I would like to know if it's necessary to configure the Link Backup feature, and if I do it, how it will work, how it will be the logic. Does one feature depends on the other?

Thanks in advance and sorry for my bad English.
Regards.
