Hi all, we have a number of MLXe's with MR2-X management and -X line cards. I'm currently running the multi-service-4 cam profile and have ip-cache and ip-route set to 1048576.
It appears IPv6 adoption has finally gotten us to the point where internet BGP routers are seeing enough v6 routes to create a problem:
Aug 31 11:51:10:A:CAM IPv6 partition warning: total 32768 (reserved 0), free 1602, slot 3, ppcr 1
I'm seeing between 30988 and 31101 advertisements from providers I peer with, so we're very close:
[IPV6] 32768(size), 1589(free), 095.15%(used)
I'm curious if, in later software builds, there is any way to increase the IPv6 CAM allocation independent of changing to the ipv4-ipv6-2 profile? I have a management VRF defined on the routers, and, at least in year 2014, ipv4-ipv6-2 breaks that since it allocates zero space to IPv4 VPN which a VRF draws from.

It should be possible to increase the allocation to the items you specifically want to increase, for instance to increase ipv6-route and ipv6-cache (both should be increased)
MLX(config)# system-max ipv6-route 65535
MLX(config)# system-max ipv6-cache 65535
This will require a reload to change values after completing a wr mem
The configured values can be confirmed by using command show default values
hope this helps
