Unreachable next-hop route remaining in routing table

Hello! I'm checking out about this issue almost one week but didn't find anything.

 

We have a NX9K and two EBGP peers which we are receiving routes from the respective ISPs. However, one of them (unfortunately, the main) is advertising some routes which we suddenly become unable to reach the next-hop (always the same). However, even next-hop is unreachable the route still remains in the routing table. I'm looking for some way  don't let the routes remain there once the next-hop become unreachable.

Some one could help with that?

Hello

Just to confirm your receiving ebgp prefixes from you ISP even though your ISP next-hop is not reachable?
Can you post the following:

Sh ip route bgp
sh ip bgp | B N
sh ip bgp x.x.x.x  <---bgp route that is unreachable
sh run | sec router
