Howdy Charles, Perhaps I can help with your BGP question.
[snip] Has anyone tried anything similar with BGP (or similar routing protocols)? It seems reasonable to expect a router that's not too many hops away (ie the ISP, or the ISP's upstream provider) would be running BGP, and while it's hopefully not possible to alter the route list, it might be possible to import route information. [...] Charles Steinkuehler [/snip] BGP will not talk to just anybody. It will only send and receive information with 'peers' and 'peers' are statically configured when you set up BGP. This can be slightly confusing since BGP is a dynamic routing protocol. The peering sessions are static, although the routing tables and routing information that passes between the peers is dynamic. The best reference for load balancing is Jack Coates site. He does a great job of summing up the major concerns with load balancing and offering suggestions on how to make it work. There is some great information there and it is a quick read. Here is the link... http://www.leaf-project.org/pub/doc/howto/LRP-Load-Balancing-HOWTO.html Hope this helps.

At the moment, I have a work-related SDSL connection (sadly, it's only 384K, rather than the 1.1 MBit I used to have...I moved farther away from the CO :< ), as well as the personal cable-modem link (dynamic IP from cox.net) I had at home prior to moving my office. I'm eventually going to get rid of the cable-modem connection to save money, but before I do, it's the first time I've had a real-world environment for testing multiple uplink configurations. Anyone got any ideas they'd like to see tested? I can't devote a lot of time to this (I still haven't even managed to get an updated Dachstein-CD out with the new ssh packages), but I can probably spend a couple evenings trying out a few things. Also...I recently got a nifty trick from the local linux users group regarding time-servers: <quote> > Does someone knows of a time server that I can use to > synchronize my linux box at boot time? There are a bunch listed at www.ntp.org, a.k.a. www.eecis.udel.edu/~ntp. A possibly better alternative is to use your provider - most ISPs enable NTP on their routers. This is convenient for them, since they can correlate router log messages accurately. It's convenient for you, since you have a low-latency time source just a few milliseconds away. Tru running "ntpdate -q" against a traceroute output, e.g. traceroute -n www.cnn.com | head -5 | awk '{print $2}' | \ xargs -n 1 ntpdate -q You'll usually find an NTP server close by. </quote> Has anyone tried anything similar with BGP (or similar routing protocols)? It seems reasonable to expect a router that's not too many hops away (ie the ISP, or the ISP's upstream provider) would be running BGP, and while it's hopefully not possible to alter the route list, it might be possible to import route information. If you could do this on both links, and run BGP on the LEAF box, you could do *REAL* load-balancing (or am I missing something major here? I don't do much backbone type setup/config, so I could be completely off-base).
