I have a static route that's stuck in 'inactive' state and not being inserted
into the kernel routing table, and I can't figure out why.
Can anyone shed light on this?
FRRouting 10.0 on Linux(5.15.0-112-generic), Ubuntu 22.04.
I have three static routes in my configuration:
- --- cut ---
ip route 10.0.0.0/8 192.168.146.134 vrrp4-1-2
ip route 172.16.0.0/12 192.168.146.134 vrrp4-1-2
ip route 192.168.0.0/16 192.168.146.134 vrrp4-1-2
- --- cut ---
Two of them work but the 192.168.0.0/16 route is stuck "inactive" in the
output of 'show ip route static':
- --- cut ---

Looking at the routes on the machine, I see routes for the 10/8 and 172.16/12,
but not 192.168/16:
- --- cut ---
10.0.0.0/8 nhid 84 via 192.168.146.134 dev vrrp4-1-2 proto static metric 20 onlink
172.16.0.0/12 nhid 84 via 192.168.146.134 dev vrrp4-1-2 proto static metric 20 onlink
- --- cut ---
Thanks.
