I think I read somewhere online something similar to what you are
suggesting. My first thought was, that was unusual, but looks like this
is the last option for me.

This does look like an issue with the dual sup configuration :(.
You may need cisco support to sort it out.
One solution may be to remove the second sup while configuring
And then reinserting it once the box is booted with the desired configuration.

Issuing just "reload" should have been fine, no? I've always done it like that
multiple times trying different values.
I suspect, as Mack pointed earlier, the new values are not copied to the
slave-sup after a write mem, but it never gets copied.

On my OP, I mentioned that I have two supervising engine on SSO mode
which
is:
1 5 Route Switch Processor 720 10GE (Activ RSP720-3CXL-10GE
2 5 Route Switch Processor 720 10GE (Hot) RSP720-3CXL-10GE
Though, the second one was added much later. I was running
c7600rsp72043-adventerprisek9-mz.153-1.S1.bin before but now I updated
it to c7600rsp72043-adventerprisek9-mz.153-3.S3.bin.
Running "sh mls cef max", I see:
#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 + MPLS - 512k (default)
IPv6 + IP Multicast - 256k (default)
User configured :-
---------------
IPv4 - 768k
MPLS - 24k
IPv6 + IP Multicast - 112k (default)
Upon reboot :-
-----------
IPv4 - 768k
MPLS - 24k
IPv6 + IP Multicast - 112k (default)
BUT "remote command switch show mls cef max", I see:
FIB TCAM maximum routes :
=======================
Current :-
-------
IPv4 + MPLS - 512k (default)
IPv6 + IP Multicast - 256k (default)
Could this mean that the two sups are not sync? Here is the output of
show redundancy states:
#sh redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 1
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = sso
Maintenance Mode = Disabled
Communications = Up
client count = 169
client_notification_TMR = 30000 milliseconds
keep_alive TMR = 9000 milliseconds
keep_alive count = 1
keep_alive threshold = 18
RF debug mask = 0x0

This is a silly question but do you have dual sups?
That could be causing the issue.
Also what code revision are you running?
Finally, what line cards are installed?
The message you are getting indicates the config is not working For
whatever reason, one of the reasons could be line card incompatibility.
A show module should list the line cards.
Also once you configure the routes on the supervisor and save the
config Execute the following command:
remote command switch show mls cef max
That will determine if the max routes command is getting properly
Pushed to the switch processor.
And a side note multicast and ipv6 both use two entries.
The other poster that said you were 28 short was incorrect.
Those settings should have worked.

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

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,
