Hello to all,

 

I have two uplinks via ethernet,

 

One on Fiber optic converter

Second Adsl

 

How to make One - primary uplink

And if traffic not pass first uplinks - flow trafficevia second uplink.

 

Two different providers which not want to setup any of routing protocols with fault detection.

 

Thanks A lot Yuriy.

Hi Yuriy,

 

Have a look at using qualified next hops with a probe to the default gateway and a script to increase the metric on the 2nd link in the event of a failure.

 

This has been talked about before:

You can even load balance the traffic between these two links, for more efficiency, by using Filter Based Forwarding (FBF).

This Solution not full.

One person advice to delete next-hop

Second advice increase metric.

But no solution for return to default state.

 

I am new in JunOS, where I can find some examples for my case without change Firmware to 11.x

 

Thanks

No, it's not acceptable because we have a huge amount of TCP sessions which we want to save.

If I will use two links simuatiosly -  I increase posibility of disconnection.
