But for the same effort (and some cheap RAM) you can have the full table and do some traffic engineering if you want to. -Aarno -- Aarno Aukia Atrila GmbH Switzerland - To unsubscribe, e-mail: discussion-unsubscr...@pfsense.com For additional commands, e-mail: discussion-h...@pfsense.com Commercial support available - https://portal.pfsense.org

Evgeny There is none, you get away with two default routes from your ISPs if you just want failover. But for the same effort (and some cheap RAM) you can have the full table and do some traffic engineering if you want to. There's generally three options when choosing what kind of feed to receive from an upstream -- full feeds, partial customer-only routes, or default routes only. With full feeds, you'll have full redundancy for outbound traffic also and will be able to (to an extent) detect routing problems further up the path, i.e. in connectivity from ISP A to ISP C, upstream. It will also help protect against failures where layer 2 and 3 is up on the circuit but there are problems with your network provider's routing. Full routes are very important for redundancy but require a considerable amount of memory in router land, which is where partial routes (so you at least know which networks the ISP has) and default-only routes come in. -- William R.

Yes, this is from BGP theory. Returning to pfSense... memory is not an issue nowadays, what about CPU usage? Does anybody have data about CPU load when convergence happens with 'full feeds'?

I am running several pfSense-BGP installations but they are all for redundancy purposes over several links. Does anybody run pfSense with BGP and two Internet providers? My concern is default gateway... if you have to specify default gateway when you configure WAN interface then it should have less metric as the one received via BGP. May be I am missing something here. Thanks. I do. It requires removing the default gateway from the XML and not visiting the WAN page again afterwards. Works fine, has been in use for over a year now since the 2008 hackathon. Scott Thank you. Do you have xml for 1.2.3-RC3 so I could try it?
