[c-nsp] exceeding the hardware maximum routes in a 720BXL

[Gordon Bezzina]

Hi,

Just a quick question what will happen if you exceed the maximum routes
That the FIB TCAM can store.

c7600#sh mls cef maximum-routes 
FIB TCAM maximum routes :
=======================
Current :-
-------
 IPv4 + MPLS         - 512k (default)
 IPv6 + IP Multicast - 256k (default)


c7600#


Will switch completely to software routing, or just switch the
Excess routes to software routing? Or will it drop routes or worst
Still crash!?


Also is there a best practice on changing the default maximum routes
Allocations?


Thanks
Gordon
