Failover Route using DHCP provided gateway
Closed, ResolvedPublicFEATURE REQUEST
Actions

Description

It would be extremely useful to be able to use failover routes using DHCP provided gateway, instead of having to specify the next-hop.

For example something like:

set protocols failover route 1.2.3.4/32 dhcp-interface 'eth0' check target '1.1.1.1'
set protocols failover route 1.2.3.4/32 dhcp-interface 'eth0' check timeout '5'
set protocols failover route 1.2.3.4/32 dhcp-interface 'eth0' check type 'icmp'
set protocols failover route 1.2.3.4/32 dhcp-interface 'eth0' interface 'wg2'
set protocols failover route 1.2.3.4/32 dhcp-interface 'eth0' metric '10'

100% agree. I have submitted a similar feature request here:

Do static addresses/gateways work stable enough?

Oops, I didn't see T5647! Sorry! I guess this one can be closed as a duplicate.

Static next-hop addresses with failover routes work fine for me.

Can confirm, short term testing worked.

I couldn't test long term as I had to statically assign my DHCP assigned IPs for testing.

Forum thread with a nice workaround by giuppo77: https://forum.vyos.io/t/wan-failover-with-dhcp/
Not a generic solution but maybe an inspiration for implementation.

That is awesome. Do you have any plans on adding PPPoE interface support?
