Hello!
I've attached a patch that allows (selectively) exchanging LOCAL_PREF with eBGP peers.
The BGP RFC (RFC4271) says that you shouldn't send LOCAL_PREF to eBGP peers, but most modern BGP implementations have an override to allow doing this anyway, and it is very useful in some scenarios, for example if you have a network topology a la RFC7938.
This patch enables this functionality by the 'ebgp localpref' clause in a bgp protocol statement, for example:
protocol bgp mypeer { [...]; ebgp localpref rx; }
This option works like 'add paths', in that the possible arguments are "rx" or "tx" or a bool (where "yes" means both rx and tx).
Hello I think it is a useful feature. But rx/tx values seems like a bit overengineering. If for some obscure reason someone wants it just one way, it can easily be done in filters. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
