Someone from the maker of BIND company for DNS came here, and he told us that he's using OSPF to load balance the server, I don't know how he did it. Unless he's using the small routers to do it for servers. -----Original Message----- From: tony bourke [mailto:tony@vegan.net] Sent: Friday, July 07, 2000 9:12 AM To: Sutantyo, Danny Cc: lb-l@vegan.net; nanog@merit.edu Subject: RE: LoadBalancing products: Foundry ServerIron Hi Danny, I'm not sure what you mean. Are you talking about load balancing routers? Or load balancing output from load balancers? Tony On Fri, 7 Jul 2000, Sutantyo, Danny wrote:
How about load balancing on the router? Any idea? I heard someone is using ospf method to load balance?

True, thats why I don't particularly like LocalDirectors. Most of the other load balancing solutions do offer GigE, however. I prefer LB over clustering as it gives you more flexibility in what you use as far as your platform. Microsoft's clustering software limits you to microsoft, while I'm not sure if resonate will let you do both UNIX and Windows.
The implementation is alot simpler as well, the LB is bascially acting as a glorified router in most cases, so its a very logical and elegant solutions. Clustering, at least in my experience, tends to be more combersome and complex to setup.
But that is just my humble opinion.
LB vs Clustering sounds like a possible religeous debate ;)

Yeah, so why bother? As long as load balancers don't have GigE ports, I can't use them and have to use something like Resonate. Besides, LBs don't do site-site load balancing. If you want to do distributed load sharing then there really isn't much choice. Personally, I don't see benefits of LBs that proper clustering wont give you. Component clusters work well, much better than simple LB will give you.

you can do EtherChannel for more than 100 Mbps, but we all know how well that works.

The last time I looked at one, I couldn't get it in GigE...100baseTX only. Ergo, I couldn't run it on my

How about Local Director?

Products are also available from Alteon, Cisco (Distributed Director) and Resonate. Last time I looked, none of these products does everything one wants, IMHO, but the set union of features comes pretty close.

There are two servers that provide f.root-servers.net service; each has the f.root-servers.net address configured as an alias on the loopback interface. The servers and the two upstream routers run OSPF; the servers each inject f.root-servers.net/32 into OSPF, and the routers see two "offers" of f.root-servers.net/32 with equal cost. The routers do CEF per-destination load-splitting, which winds up splitting the load roughly 60/40 between the two servers. Stephen
I thought that Cisco was junking the Local Director and planning to migrate all their customers to the newly aquired Arrowpoint technology.
