BGP neighbor range

[sokacem]

Hi

i want to ask if there is a possibility with the FRR plugin to configure a network range in BGP neighbors

all the Firewalls/Routers will share a same network and have the same AS, so it's very heavy and tedious to enter and configure neighbor per neighbor on each Firewall/Router

this functionality is present on FORTIGATE

i m trying to setup a VPN, HUB to SPOKE architecture, so using a BGP neighbor range will ease a lot such setup

Thanks a lot

Are you about 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?

What do you mean "i think the FRR plugin there not yet having the implementation of BGP network range"?

[sokacem]

well, in OPNsense Firewall, you can add many things as packages or plugins
FRR exist as a plugin and its version is 1.40_1

so when you add the FRR plugin, a menu named (Routing) appears where you can configure the FRR parameters
there is sub menus General, RIP, OSPF, OSPFv3, BGP, BFD, STATIC, Diagnostics

in the BGP section, there is nowhere to configure the BGP listen range, there is just the following sub menus for the BGP section :
General, Neighbors, AS Path Lists, Prefix Lists, Community Lists, Route Maps, Peer Groups

and in Neighbors section, there is only the possibility to add (Peer-IP) not a list range, so the only option is to add neighbor per neighbor

Then OPNsense is missing the features that FRR has.
