Router is ignoring dhcp-options no-default-route

Aloha,

Im on version 1.5
I have different uplink provider.
For that I like to use the failover feature, to track a host and switch default route.
https://docs.vyos.io/en/latest/configuration/protocols/failover.html

For 2 uplink provider I have to use DHCP.
Unfortunately vyos is ignoring the "dhcp-options no-default-route
knob

set interfaces bonding bond1 vif 66 address 'dhcp'
set interfaces bonding bond1 vif 66 dhcp-options no-default-route

sh ip route 0.0.0.0/0
Routing entry for 0.0.0.0/0
  Known via "static", ***distance 210***, metric 0, tag 210
  Last update 00:09:15 ago
    100.64.0.1, via bond1.66, weight 1

set protocols failover route 0.0.0.0/0 next-hop 100.64.0.1 check target '9.9.9.9'
set protocols failover route 0.0.0.0/0 next-hop 100.64.0.1 check timeout '5'
set protocols failover route 0.0.0.0/0 next-hop 100.64.0.1 check type 'icmp'
set protocols failover route 0.0.0.0/0 next-hop 100.64.0.1 interface 'bond1.66'
set protocols failover route 0.0.0.0/0 next-hop 100.64.0.1 metric '20'

The failover route should work:

traceroute 9.9.9.9 interface bond1.66 bypass 
traceroute to 9.9.9.9 (9.9.9.9), 30 hops max, 60 byte packets

I encountered this myself a while ago. Please add any details you can to this ticket. I do find the comment by giuavo interesting, I need to check that.

I am my ISP, so it shouldn’t be too hard to test, I just haven’t got around to testing it.
