hi list! i'm trying to find a convenient way to build a redundant filtering bridge under linux i looked at carp project, but carp doesn't support bridge now i thing the most appropriate way is using stp or rstp it seems that 2.6 kernel supports stp but what about rstp? I read some docs about stp, but they are rather outdated (2001 and kernel 2.2) there are several problems indeed: * rstp support * fw state sync * fw rules sync did some of you resolve these problems? any help appreciated, i'm rather confused between rstp, stp, ct_sync, conntrackd ... ps: next step will be trafic shaping / load balancing implementation within this setup, again, any help appreciated!
