# Redundancy w/o aggregation and AstraMUX
{% hint style="danger" %}
**CAUTION**
Configurations from the scenarios below are examples that demonstrate the potential capabilities of the Astra Wireless devices. The configurations may vary depending on the model and firmware version. We do not recommend copying this solutions to the hardware without checking.
{% endhint %}
### Description
It is easy to fully reserve a connection by combining two radio channels into one MINT domain. The traffic path will be automatically selected based on the quality of each radio link in this case.
### Configuration Example
A management is VLAN 100 in switch group #100. A transport of user data is in switch group #1.
#### Configure Master 1 and Slave 1 as the main link.

#### Create united MINT domain.
**Master 1**
```
ifc prf0 up
prf 0 parent eth0
mint prf0 -name "Master 1 prf"
mint prf0 -nodeid 00050
mint prf0 -type master
mint prf0 -mode fixed
mint prf0 -key "123456789"
mint prf0 -authmode public
mint prf0 start
mint join rf6.0 prf0
```
**Slave 1**
```
ifc prf0 up
prf 0 parent eth0
mint prf0 -name "Slave 1 prf"
mint prf0 -nodeid 00060
mint prf0 -type master
mint prf0 -mode fixed
mint prf0 -key "123456789"
mint prf0 -authmode public
mint prf0 start

```
**Master 2**
```
ifc prf0 up
prf 0 parent eth0
mint prf0 -name "Master 2 prf"
mint prf0 -nodeid 00070
mint prf0 -type master
mint prf0 -mode fixed
mint prf0 -key "123456789"
mint prf0 -authmode public
mint prf0 start
mint join rf6.0 prf0
```
**Slave 2**
```
ifc prf0 up
prf 0 parent eth0
mint prf0 -name "Slave 2 prf"
mint prf0 -nodeid 00080
mint prf0 -type master
mint prf0 -mode fixed
mint prf0 -key "123456789"
mint prf0 -authmode public
mint prf0 start
mint join rf6.0 prf0
```
#### Configure switch groups.
{% hint style="danger" %}
**CAUTION**
If you do not exclude the interface eth0 on one of the devices or do not enable STP, then there will be a loop.
{% endhint %}
The STP protocol is used to eliminate the loop In the example below.
**Master 1**
```
switch group 1 add eth0 prf0
sw group 1 stp on
switch group 1 start
```
**Master 2**
switch group 1 add eth0 prf0
sw group 1 stp on
switch group 1 start
**Slave 1**
```
switch group 1 add eth0 prf0
sw group 1 stp on
switch group 1 start
```
**Slave 2**
```
switch group 1 add eth0 prf0
sw group 1 stp on
switch group 1 start
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://wiki.astrawireless.net/astra-wireless-documentation/white-papers/link-aggregation-balancing-and-redundancy/astra-evolution/redundancy-w-o-aggregation-and-astramux.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
