Describe the bug

When activating BFD Strict Mode along with BFD, BFD and BFD Strict Mode removes from the BGP neighbor in FRR. When removing BFD Strict Mode, then bfd and bfd strict mode appears in config, then it vanishes after some time.

Look at screenshots.

To Reproduce

Steps to reproduce the behavior:

1. Go to Routing -> BGP -> Neighbors
2. Click on (Edit) Neighbor
3. Scroll down to BFD Strict Mode.
4. Look at live results in vtysh (via terminal/SSH) using show run and checking neighbor config.

Expected behavior

BFD along with BFD Strict Mode should enable

bfd
bfd strict mode

In BGP neighbor config.

Screenshots

See attachments. When BFD Strict Mode is unselected, it get's activated in the running config, if i enable it both bfd and bfd strict mode vanishes from running config.

Environment

Software version used and hardware type if relevant, e.g.:

OPNsense 26.7.1

Start in Routing → BGP → Neighbors and reproduce the behavior by checking vtysh show run for the neighbor configuration. Trace how the BFD and BFD Strict Mode settings are handled, then verify that enabling both retains bfd and bfd strict mode in the running configuration and that changing the toggle does not make them disappear unexpectedly.
