Good morning
I have here at home two RB750G r3, one serving a DSL line and the other a cable line, both with fixed IP addresses from ISP.
What is the best way to achieve an automatic fail-over when one of the line goes down or starts flapping like during this week?
And what is the best routing protocol in terms of CPU usage for distributing traffic of certain prefixes among the RB750s?
Like IPTV goes preferred over DSL and NNTP over cable…
thanks in advance

You only need one router to ingest the two ISPs??
No…each router is connected to its own ISP…as someone mentioned that RB can’t handle two WAN links…at least the switching fabric in RB750 is limited…
A single RB750r3 should have no problem to cope with both a DSL and cable line and is probably the easiest way to handle automatic failover and other stuff like splitting distribution of transmission types.
Check out: “Advanced Routing Failover without Scripting” and “Failover (WAN Backup)”
As larsa said bullocks!!
My first router was the 750Gr and I used it for dual wan failover just fine. What it couldnt do is handle 1gig throughput when I upgraded my wan connection so moved it over to act as a switch. Who was giving you said advice??
The single WAN is published on several online shops like here:

Have to find an elegant way how to wire the telephone cable from ground floor to first floor where all my network equipment is…
and as both lines deliver more than 0.5GB a more power-full router needs to be ordered then.
But sadly currently not many powerful routers are on stock at the moment here…and those that are have a shared 1GB or 2.5GB switching fabric…
You plan on using load balancing between the two ISP then? If its failover, the 750Gr is fine.
Choices to handle 1 gig for example… Personally the RB5009 is a good investment.
hapac2 (old wifi - )
hapac3 ( old wifi - )
RB450Gx4 (routerboard, needs case and power supply )
RB4011 (wired router a bit aged but still Vgood)
RB5009 (wired router)
If only RB5009 was somewhere to be found …
That’s what I meant (o;
Seen also other switch/router manufacturers face the chip shortage problem…
And yes…sort of load balancing is the idea…like IPTV on one line preferred and NNTP on other to not disturb when my wife is watching telly (o;
Seems only the RB1100AHX4 is available at the moment with 3 * 2.5GB switching fabrics…
though no idea what the 3rd fabric called “bypass group” means in this model…
Im having a similar issue, cannot get a Toyota Rav4Prime to replace my rusting van…
