Hmm.. I did try it that way earlier, but I'm getting the same issue: # setfib 2 netstat -rn Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 10.0.3.1 UGS 0 0 vlan3 10.0.4.0/24 link#13 U 0 0 vlan4 10.0.4.13/32 link#13 U 0 0 vlan4 10.0.4.16/32 link#13 U 0 0 vlan4 127.0.0.1 link#10 UH 0 0 lo0 # setfib 2 route delete 10.0.4.0/24 route: writing to routing socket: Address already in use delete net 10.0.4.0 fib 2: gateway uses the same route Is there a way to delete it without deleting the IP from the interface?
