OSPF area-type nssa translate 'never'

Bugs

Hello,
I probably found a bug when i try to “set translate ‘never’” and no-summary in an nssa area, what i see on vyos it’s different from what is setted on frr…

sh conf commands, show it correctly:
…
set protocols ospf area 0.0.0.10 area-type nssa no-summary
set protocols ospf area 0.0.0.10 area-type nssa translate ‘never’
…

But if i check on frr:

router ospf
ospf router-id X.X.X.X
auto-cost reference-bandwidth 100
timers throttle spf 200 1000 10000
redistribute nhrp
network X.X.X.X/32 area 0
network Y.Y.Y.Y/28 area 0
network Y.Y.Y.Z/28 area 0.0.0.10
area 0.0.0.10 nssa
exit
!

I can set it from vtysh in this way:

area 0.0.0.10 nssa translate-never no-summary

Version: VyOS 2025.05.13-0019-rolling

What do you see in the FRR with this command or incomplete?
If nothing it could indicate there is a default behaviour for FRR

I would like to simulate on GNS3 to create a case… is a GNS3 image available or i need to build a current with QEMU and virtual support? because all support for virtual env was removed from night build----
