Your requirements are not clearly defined.
You can setup more than 1 RADIUS server and it WILL use the 2nd server when the first times out.
However, it will NOT try the second server when the first replies with “invalid user”.
This is true for almost any product on the market.
When you have special requirements like “try server 1 and when user not available there try server 2”
you need to setup a RADIUS proxy server that is configured to do that.

Also it is possible to use multiple Radius servers at the same time, but then, for example, one must be used for hotspot service and other for ppp (services must differ).

Thanks For reply

1- I want use For only PPPOE Auth users

Explain My Router Auth user From Radius 1 If failed Or invalid username Or timeout Next Request send to Radius Number 2

I already explained: this is not possible.
Make a RADIUS proxy or make 1 of the RADIUS servers proxy for the other.

Freeradius.
But first you will have to introduce “realms” (@domainname) for your usernames to know where the request has to be handled.
Start that migration first.
