Error not creating ip route for dhcp-interface rules on boot
Needs testing, NormalPublic
Actions

Description

1 scenario as follows:

set interfaces ethernet eth0 address 'dhcp'
set interfaces ethernet eth1 address 'dhcp'
set protocols static table 100 route 0.0.0.0/0 dhcp-interface eth0
set protocols static table 110 route 0.0.0.0/0 dhcp-interface eth1

When I commit:

show ip route table 110
Codes: K - kernel route, C - connected, L - local, S - static,
       R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
       T - Table, v - VNC, V - VNC-Direct, A - Babel, F - PBR,
       f - OpenFabric, t - Table-Direct,
       > - selected route, * - FIB route, q - queued, r - rejected, b - backup
       t - trapped, o - offload failure

VRF default table 110:
S>* 0.0.0.0/0 [1/0] is directly connected, eth1, weight 1, 00:03:07
  *                 via 192.168.1.1, eth1, weight 1, 00:03:07

Then I rebooted (made sure to save)

I used to use VyOS Stream 2025 Q1 version, it worked correctly. Recently I switched to VyOS Rolling and it crashed here

I found the cause. You need to mark which interface will run it.

set policy route <name> interface <iface>

Oh, the problem still persists. I need someone to help, because I only get this error on a few infrastructures.
