Number of LSAs is much more important than number of routers, per se. If you
can keep your number of external routes down, and keep the number of network
LSAs down, so that most of your LSAs are Router LSAs, you can squeeze quite
a few routers into your backbone area.

    I seem to remember hearing somewhere that a realistic max was like 50.

      hi, gangs

      there is a questiion puzzled me long time, in reality production
environment, what 's the real max router quantity in single ospf backbone
area? RFC2329 said that the max is 1600 routers in test environment and 350
routers in reality production environment, is that true? does someone use
ospf in ISP environmrnt?

      another question is could MPLS Traffic Engineering span ospf and isis
areas? what's the IOS version.

      any reply is appreciated.
