Working default config.boot file for Ubiquiti EdgeRouter X SFP router running v1.9.0+ to replace the CenturyLink Fiber modem

Hi there, I wanted to report back here after being switched from CenturyLink to Quantum Fiber. Where I live, everyone is being switched over to Quantum Fiber from CenturyLink Fiber. If this sort of thing applies to you, and you are being moved from PPPoE to IPoE, here's what I did:

  1. Changed my eth5 config from what is described above to DHCP, removing the PPPoE entry:
ethernet eth5 {
    description "CenturyLink WAN"
    duplex auto
    speed auto
    vif 201 {
        address dhcp
        description "CenturyLink WAN VLAN"
        firewall {
            in {
                name WAN_IN
            }
            local {
                name WAN_LOCAL
            }
        }
    }
}
  1. Then, I had several instances of "pppoe5" in my config elsewhere. I replaced all of these with "eth5.201", and things started working.

I discovered this after my internet went down, and in hindsight it looks like my outage was due to my custom EdgeRouter setup. I think Quantum may have been able to auto-switch the customers who used the default CenturyLink routers from PPPoE to IPoE.
