thanks neal,
in this scenario:
h1 -- n1 -- n2 -- h2n1,n2: vpp routers.
h1,h2: hosts
1- when we remove gre tunnel [ or other virtual interfaces] 2- then adding new
sub interface [for connecting n1 to n2 ]
we can't ping from h1 to h2.

Please be more specific about what ‘doesn’t work’.
You script on n1 does:
#add gre tunnel
create gre tunnel src 200.1.2.1 dst 200.1.2.2
set interface state gre0 up
set interface ip address gre0 10.10.10.11/32
ip route add 2.1.1.0/24 via gre0
#del gre tunnel
set interface state gre0 down
create gre tunnel src 200.1.2.1 dst 200.1.2.2 del
ip route del 2.1.1.0/24 via 200.1.2.2.
that last route delete was not the route you added, so it won’t remove
anything. What you need is
ip route del 2.1.1.0/24 via gre0
and of course you need to do that before you delete the tunnel.
