From 6cace2df99c700dfaafe0d414257e4c3a9061771 Mon Sep 17 00:00:00 2001 From: Viacheslav Hletenko Date: Mon, 15 Apr 2024 15:17:14 +0000 Subject: T5722: Failover route add option onlink onlink pretend that the nexthop is directly attached to this link, even if it does not match any interface prefix. Useful when gateway not in the same interface network set interfaces ethernet eth0 vif 10 address '10.20.30.1/32' set protocols static route 10.20.30.0/32 interface eth0.10 set protocols failover route 192.0.2.11/32 next-hop 10.20.30.0 onlink ``` vyos@r4# sudo ip route add 192.0.2.111/32 via 10.20.30.0 dev eth0.10 metric 1 proto failover Error: Nexthop has invalid gateway.
