[c-nsp] Full net table too large for Sup720 already?

[Jeff Fitzwater]

    It depends on how many specific routes your peers are sending you.  
If  one sends you lots of /24 routes then it could fill the table, or if 
2 peers send you a total of >230K (default) with lots of specific routes 
from one then it will also fill the CEF table space.    You could 
increase the V4 space by stealing some from V6 or multicast limits.  We 
up-ed our v4 limit by adding this command ....
mls cef maximum-routes ip 239
Do a "sho mls cef summ" to see where you are at.  

NOTE  This requires a reboot to take effect.  If you are running over 
the max you should see log messages (%MLS-xxxx) indicating you went 
over, and also routing processor cpu being high.   This fixed it for us 
but we are still close.  We have 2 full I1 and 1 full I2  ~230K I1 and 
~10K I2.  I believe the BXL doubles this limit.
