Hi,
The problem was stuck kernel route. This route was added with ip route command and later on added in zebra. When the port got down the route remained in fib of zebra with unknown interface. There was no way to remove. Through ip route del > no process.  No way to delete kernel route in zebra. Restarted frr and it resolved the problem.

HI,
I added a static route in zebra through vtysh. 
ip route x.x.x.x./y  a.a.a.a
the route is there when you do show ip route static
but it doesnt work until you add with ip route command in linux shell
ip route add x.x.x.x/y via a.a.a.a
the interface is ppppoeXXX and the name keeps on changing. 
Kindly help to make static route working.
