Thank you for the information. What I'm also interested is what is the typical number of OSPF area in today's large ISP backbone (if they are using OSPF, not IS-IS). Anyone has some input? Thanks, Hansen "Daniel L. Golding" wrote:

The important part is to limit external routes being redistributed into OSPF. External routes are bad mojo.

According to OSPF books, a typical area is consisted of 200 routers. Are those guidelines ever followed in real ISP network deployment? Any input is highly appreciated. Cheers, Hansen
