I have two gateways in a PCC balancing environment.

One is an ethernet router and it is checked with check-gateway=ping
The other one is a dsl modem and MT device provides PPPoE call (thus, getting the IP address from ISP)

What's the method to check if PPPoE connection is available , for failover purpose ?

Thank you

Note if the gateway the PPPoE connection is adding is always the same. Check if it responds to pings.

If so, you can untick Add Default Route on the PPPoE client Dial Out tab, and set the route statically, enabling Check Gateway: ping for that route.

The gateway ip is the one at the remote end of your point to point PPPoE connection, so won't be available if the PPPoE connection is stuck or down.

You're right, but I don't know my ISP gateway IP address.

The public IP address released by ISP PPPoE server is what they call a /32 address ip , over an "unnumbered" ip interface (don't ask me if it is true or what do they mean.....)
I can know the ISP first hop but i'm not sure if IT is the gateway , and if it is always the same gateway either

Just realized that , however, that failover is intrinsic in pppoe connection.
In fact, if I disconnect dsl line or provider drops the connection, that route becomes inactive (gateway unreachable) as soon as MT is aware of, without the need of ping to anything....

Thank you anyway

Hello, I would like to refresh this topic.
I have main connection VDSL PPPoE (with IP/32, no GW IP) and backup connection LTE.
Router is RB 3011.
Is there any possibility to set gateway_check in route setting to create failover?
Thank you for any advice
