How-to-enable-2-Million-routes-on-MLX-platform

Hello,

I have noticed that 

https://extremeportal.force.com/ExtrArticleDetail?an=000086063

is not 100% complete and it is missing some crucial example information at the end.

To use the X2 scalability for the DFZ with double density you need to do the following things (besides having X2 cards and X-Management cards):

1.) Set algorithmic mode for the X2 cards:

 (config)# cam-mode amod slot 4
 (config)# cam-mode amod slot 6

2.) Set one of the valid cam-profiles:

# cam-partition profile ipv4-ipv6-2
# cam-partition profile multiservice-6
# cam-partition profile default

3.) Missing in the knowledge base article: Set the IPv4 and IPv6 system-max values to increased values, else it will always boot in  decreased -X defaults, for example.

system-max ipv6-cache 1884160
system-max ipv6-route 1884160
system-max ip-cache 2621440
system-max ip-route 2506752

4.) Reload the chassis (remove all -X / -M cards before):

reload

5.) After boot up, validate :

show ip cache
show ipv6 cache
show cam-partition slot 4
show cam-partition slot 6

Hope this is helpful and saves somebody time (not like me :D).
