    Hi Mohammad,
    You are trying to configure floating static route incase if one nexthop fails the other must take over.Is this right?
    You can achieve this using Flow redirect feature.
    Example:

    create flow-redirect gilly------------------this is just a name
    configure flow-redirect flow_redirect_name add nexthop 192.168.92.1 priority 100
    configure flow-redirect flow_redirect_name add nexthop 192.168.200.1 priority 200

    if match all {
    destination-address 192.168.37.0/24 ;
    } then {
    permit ;
    redirect-name gilly
    }
    }
    Note:higher priority next hop will take precedence

    regards,
    Parthiban Chinnaya

    If you are just looking for failover normal floating static route.
    then the below config must work.
    configure iproute add 192.168.37.0 255.255.255.0 192.168.92.1
    configure iproute add 192.168.50.0 255.255.255.0 192.168.92.1
    configure iproute add 192.168.50.0 255.255.255.0 192.168.200.1 200
    configure iproute add 192.168.37.0 255.255.255.0 192.168.200.1 200
    configure iproute add default 192.168.92.1

    When one of the nexthop fails do you see that route removed from Fib?

    Hai PARTHIBAN CHINNAYA

    Sorry for delay response. we have two l3 switches between one of our WAN link. So when the link is down on that time the port is not down both end. route also not also not removed.

    In this scenario the link failure is not detetcted thats why the route is not removed from routing table.
    I would recommend configuring BFD for static routes on both ends.
    This is the ideal solution.

    I have BFD routing set up.  I want to be able to manually fail back over to primary route when the link comes back up.  How do I go about doing this?  Meaning BFD routing works fine and removes the route but I want the route to stay removed even when the path comes back.  Then at approved time go into the switch and bring up primary path and make sure BFD routing is enabled again.
