Description

There is a bug when deleting a VRF that is the target in a next-hop-vrf.

Steps to reproduce

1: Create VRF

set vrf name Red table 10000
set vrf name Blue table 10001

2: Add interfaces

set interfaces dummy dum10000 address 2001:470:dd54:F0A::1/64
set interfaces dummy dum10000 vrf Red
set interfaces dummy dum10001 address 2001:470:dd54:F0B::1/64
set interfaces dummy dum10001 vrf Blue

3: Add Inter-VRF route from Red to Blue

set protocols vrf Red static route6 ::/0 next-hop 2001:470:dd54:F0A::2 interface dum10001

4: Delete interfaces

delete interfaces dummy dum10000
delete interfaces dummy dum10001

5: Delete VRF Blue

delete vrf name Blue

6: Create VRF Blue again

set vrf name Blue table 10001

returns

[ vrf ]

That should actually not be possible with the verify() step - looks like a bug in the code
