Tracking of an unused prefix received via bgp (next-hop)

Hello!

The task is to find EXOS (X590 and X690) functionality similar to Cisco.

Cisco is track of an unused prefix received via BGP:

track 100 ip route 192.168.1.3/32 reachability
track 110 ip route 192.168.1.4/32 reachability

Route-map on the Cisco Nexus:

route-map TO-NAT deny 10
match ip address TO-NAT-DENY
route-map TO-NAT permit 20
match ip address TO-NAT-PERMIT
set ip next-hop verify-availability 192.168.0.1 track 100
set ip next-hop verify-availability 192.168.0.2 track 110 force-order

Based on tracking availability, it is sent to the desired next-hop
force-order is needed to restore the main node
BGP is only used for signaling - node availability.

Checked EXOS flow-redirect, but it uses ARP, NDP, or PING to make a decision. But we need BGP.

Any ideas?
