You might want to better define "scalable". I don't know your background or network so I can't guess. I can say I've seen the inner workings of some large ISP networks with a lot of hosts in iBGP that work fine, and then people with 5 routers try and tell me they have a scaling problem. What is your actual problem? Memory usage? Convergence time? Configuring the sessions? Staff understanding of how it works? > I am wondering if people can point me in the direction to some good resource > material on how to select a good BGP route reflector design. Should I just > dust off some 7206VXR routers to act as route reflectors? This is a red flag to me, relative to the questions above. The 7206VXR, even with an NPE-G2, is a 1.5Ghz Power PC with a paltry 2GB of DRAM. It was not speedy when new, being roughly equivilent to the PowerPC G4 processors in Apple Laptops at the time. It is approximately 8 times slower than a current iPhone. Seriously. If convergence time is anything you care about, a 7206VXR is a very bad choice. It may also run out of memory if you have a lot of edges with full tables. So what's the actual "scaling" problem? -- Leo Bicknell - bickn...@ufp.org PGP keys at http://www.ufp.org/~bicknell/
