Hmm I somewhat tried that with these,
sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 + MPLS - 512k (default)
IPv6 + IP Multicast - 256k (default)
User configured :-
---------------
IPv4 - 768k
MPLS - 16k
IPv6 + IP Multicast - 120k (default)
Upon reboot :-
-----------
IPv4 - 768k
MPLS - 16k
IPv6 + IP Multicast - 120k (default)
but still no dice. IOS bug?

Maybe IPv6 and IP Multicast must share the same region of the TCAM.
Just try to remove all the "mls cef maximum-routes" commands then just add
this one:
mls cef maximum-routes ip 768

This is what I tried,
#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 + MPLS - 512k (default)
IPv6 + IP Multicast - 256k (default)
User configured :-
---------------
IPv4 + MPLS - 768k (default)
IPv6 - 100k
IP Multicast - 28k
After a wr mem and reboot this is what I got:
*Aug 6 02:15:46.975 PHT: %MLSCEF-SP-1-MAX_ROUTE_MISMATCH: Maximum routes
config mismatch. Reconfigure the maximum routes values and reload the box.
As you will see the max routes adds to 1024k but still It resets to the
default values.

As already mentioned, the sum should be 1024k, for example, I have
this on a
SUP720-3BXL:

=======================
Current :-
-------
IPv4 - 1007k

1007+1+(2x8) = 1024

I read before the link you sent.
BTW, Here is the output of "sh mls cef max":
#sh mls cef maximum-routes

Subject: [c-nsp] Adjusting TCAM allocation weird behavior on 7600
Hi, I'd like to ask anyone in the group who owns cisco 7600 if they
had experience when they adjusted the allocation to increase the
maximum routes for ipv4 etc. We are near the 512K ipv4 limit (~509K)
for the
7600 (default size) and I tried adjusting the tcam allocation by running:
mls cef maximum-routes ip 750
mls cef maximum-routes ipv6 100
mls cef maximum-routes mpls 10
mls cef maximum-routes ip-multicast 28
But after rebooting the whole box I got an error, "Maximum routes
config mismatch. reconfigure the maximum routes values and reload the
box" (Sorry this is all I copied from the console) and the tcam was
back to the default values.
I have a dual RSP720-3CXL-10GE sups on sso mode and
c7600rsp72043-adventerprisek9-mz.153-1.S1.bin if those info help.
Thanks,
