Cirrus
CirrusCha, it really helped:-) I dont understand the idea why I had to set static route for subnet when next hop is the same as default route...but, it works and I don't care more:-)
Thank you
AltocumulusReplying to this comment decades later but I thought if someone will refer this solution will find this helpful. It prefers the tmm route as they have the lowest metric compared to the mgmt route and to give mgmt route preference we need specific route. So that the least specific route gets selected first and dont have to go on to metric to decide.
