Hi, do you mean Software Redundant Port (SRP)?

config ports redundant {link [on | off]}

The primary and secondary port are local to the switch (or stack), they have the same configuration and no other L2 protocols on them (STP...). The primary port is the active one, the secondary is the backup. The backup comes up only if the primary fails. Link off (default) means the secondary port is not ready (led off) and so failover is a bit longer, while with link on, it's sub-second.

You can also control the behavior if the primary port comes back up, with smart redundancy.

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.

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.

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.

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?
