2024-04-16T5722: Failover route add option onlinkViacheslav Hletenko
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. [edit] vyos@r4# [edit] vyos@r4# sudo ip route add 192.0.2.111/32 via 10.20.30.0 dev eth0.10 onlink metric 1 proto failover [edit] vyos@r4# ``` (cherry picked from commit bb832acb97881d747a57da2728eab3ad138b8129)

2023-04-21T1237: Failover route add policy for targets checkingViacheslav Hletenko
Add policy (any-available|all-available) for target checking for failover route set protocols failover route 192.0.2.55/32 next-hop 192.168.122.1 check policy 'any-available' set protocols failover route 192.0.2.55/32 next-hop 192.168.122.1 check target '192.168.122.1' set protocols failover route 192.0.2.55/32 next-hop 192.168.122.1 check target '192.168.122.11' It depends if we need that all targets must be alive on just one target.
2023-04-07T1237: Failover route add checks for multiple targetsViacheslav Hletenko
There is only one target for checking ICMP/ARP Extend it for checking multiple targets set protocols failover route 192.0.2.55/32 next-hop 192.168.122.1 check target '203.0.113.1' set protocols failover route 192.0.2.55/32 next-hop 192.168.122.1 check target '203.0.113.11' The route will be installed only if all targets are 'alive'
2023-01-04T1237: Fix failover route install route with diff metricsViacheslav Hletenko
If there is no route in the routing table (requires install route) it checks routing table and returns best route None But if we have 2 routes to the same dest ip but with different metrics it doesn't get None (not first route install) It cause that bast metric route cannot be installed (wrong logic) Add func "is_route_exists" and check route/gateway/metric for the required route
2022-12-14routing: T1237: Add new feature failover routeViacheslav Hletenko
Failover route allows to install static routes to the kernel routing table only if required target or gateway is alive When target or gateway doesn't respond for ICMP/ARP checks this route deleted from the routing table Routes are marked as protocol 'failover' (rt_protos) cat /etc/iproute2/rt_protos.d/failover.conf 111 failover ip route add 203.0.113.1 metric 2 via 192.0.2.1 dev eth0 proto failover $ sudo ip route show proto failover 203.0.113.1 via 192.0.2.1 dev eth0 metric 1 So we can safely flush such routes
