BGP neighbor range (request)

[skacem]

hello

instead of having to configure bgp neighbor per neighbor, it is more interesting to configure a bgp neighbor range
FRRouting has already this functionality

https://docs.frrouting.org/en/stable-10.0/bgp.html#clicmd-bgp-listen-range-A.B.C.D-M-X-X-X-X-M-peer-group-PGNAME

the syntax is
bgp listen range <A.B.C.D/M|X:X::X:X/M> peer-group PGNAME

but it seems the FRR plugin for OPNsense doest include it yet
there is nowhere to enter the (listen range) in the Routing--BGP menu

Thanks

Thanks for this post! Exactly what I was looking for! I want to essentially accept any peers on a given internal interface, maybe limit the AS number but that can be done with filtering or whatnot. I might poke about the back end and see if it's configurable at system level, though ideally, yes have it in the plugin/GUI, if for no other reason than it doesn't get wiped on updates/reconfigurations

Hi - did you find a way to safely and consistently set `listen range` in `frr.conf` to get this to work?

[arichtman]

Sooo looks like the front-end/plugin don't support listen range but if you jam your config into FRR it works fine.
I'm working out which autorun to place a script in that just overwrites the generated `frr.conf`

Why arent you just opening a feature request instead? They do get worked on and implemented.

There was one, https://github.com/opnsense/plugins/issues/4015

Shall I request it reopened?

[Monviech (Cedrik)]

I took the issue.
