There's a route I'm trying to add that seems to be automatically deleted by something in my OS/kernel itself. I can't seem to get the origin of this or the reason. When I add the route, the command returns with success return code, but the route is automatically deleted afterwards. I understood this by running "ip monitor" while adding the route:

[admin@localhost]# ip monitor
10.0.200.0/24 via 172.28.22.77 dev eth0
Deleted 10.0.200.0/24 via 172.28.22.77 dev eth0

ifconfig output

Here's the route I'm trying to add:

ip route add 10.0.200.0/24 via 172.28.22.77

Any idea how to debug this/ find the origin?
