Failed to remove all static OIFs, after add more OIFs by ip mroute command.

[fangyuan1004]

• frr version: 614d787 (lastest)
• kernel: 4.14.76

Problem:
When I configure static mroute, by next steps. Delete mroute is error.

1. vtysh
2. configure
3. interface vlan1
4. ip mroute vlan2 239.1.1.1
5. ip mroute vlan3 239.1.1.1

I had add 2 OIFs(vlan2 and vlan3) to the IIF(vlan1) group 239.1.1.1, then I want to delete OIF vlan2. I do :
6. no ip mroute vlan2 239.1.1.1

But OIF vlan3 had been delete.
7. no ip mroute vlan2 239.1.1.1
Do nothing, because pim still want to delete OIF vlan3, and vlan3 had been delete, do pim do nothing.

Question:
How can I delete static OIF vlan2, When OIF more then one.

Can FRR PIM support removing multiple OIFs from the same route entry?
