What I met problem to understand is, 1) Is that required to route traffic from a specific BRAS to exact one server if DB behind radius server is syncronized periodically 2) There is two Farm, each has several servers. As number of paths supported by cisco/Juniper router is limited ( <= 8 or 16), we could not mix those server into one farm. is there any way to balance load between two or more farms automatically? > > Load balancing is trickier when RADIUS servers and > NASes live on the > same network segment.

I think even NASes and radius live on the same ethernet, OSPF/IS-IS could establish equal cost paths. thanks Joe __________________________________ Do you Yahoo!? Yahoo!
