Description
Important notices
Before you add a new report, we ask you kindly to acknowledge the following:
- I have read the contributing guide lines at https://github.com/opnsense/plugins/blob/master/CONTRIBUTING.md
- I have searched the existing issues, open and closed, and I'm convinced that mine is new.
- When the request is meant for an existing plugin, I've added its name to the title.
Is your feature request related to a problem? Please describe.
BFD neighbor configuration currently lacks local-address and interface options, which are required for:
- IPv6 peers (local-address is mandatory)
- Specifying which interface to use for BFD sessions (sometimes BFD can't trigger BGP without interface)
Describe the solution you'd like
Add two optional fields to BFD neighbor dialog:
- Local Address: IP address to bind and send packets from
- Interface: Dropdown to select which interface to use
Describe alternatives you've considered
No alternatives considered. This is a standard FRR feature documented at https://docs.frrouting.org/en/latest/bfd.html#bfdd-commands that complements the existing BFD support in the plugin.
