I suspect you may need to use multi-service-4 to give cam resources for IPv4 VPN (or whatever profile fits your needs that contains IPv4/6 VPN). The ipv4-ipv6-2 has no IPv4 VPN or IPv6 VPN resources allocated in it. See if that works.

Would a cam profile change affect layer 3 services in a VRF? :-)

I just switched a test router to ipv4-ipv6-2 from default and lost my management access via network. I have a management vrf defined with a gig port member since the management port can't be in a management vrf in the code version I'm running. After the reload, the router still responds to arp requests but won't talk ssh, snmp or ntp, which are the only services I have enabled, or respond to ping. All the normal stuff not in the vrf came up fine (bgp & ospf).

David,

I think ipv4-ipv6 is there really to preserve prior deployments that may justify any adjustments to the cam-profile. I haven't found anyone who uses that for any new deployments, unless its just for testing or just very basic layer3.

In most cases ipv4-ipv6-2 or multi-service-4 (or whatever its called) seem the most attractive in comparison. This is all in reference to XMR/MLXe. MLX itself (with or with out -X cards), is a different story.

Also, I think the cards state that they support 1million routes, but I don't think there is a cam profile for exactly 1million routes for IPv4..the rest of the capabilities get spread across ipv4/mpls/mac address/acl's, etc.

SSH@router#show mod | inc S2
S2: BR-MLX-10Gx4-X 4-port 10GbE Module
CARD_STATE_UP
SSH@router#show cam-partition usage slot 2

CAM partitioning profile: ipv4-ipv6-2

Slot 2 XPP20SP 0:
[IP] 786432(size), 282381(free), 064.09%(used)

Trying to understand when you'd want to use ipv4-ipv6 vs
ipv4-ipv6-2

Thanks,

David

James,

Did you also change the cam-partiion profile you are using?

router#sh cam-part | i profile
CAM partitioning profile: ipv4-ipv6-2

If you're using the default profile, it will still have the tcam carved
for 512k IPv4 routes.

Also, updating the cam profile takes a reload.

Regards,
Mike

Hi All

We are using both 5.3d and 5.4d on different devices and getting
the same errors on different MLXe X platform, which should support 1
million routes.

CAM IP partition warning: total 524288 (reserved 0), free 26214,
slot 3, ppcr 1

However we have increased the ip-route and ip-cache cam to
maximum:

Whilst the error is for 500k routes the maximum is set to 1
million routes, what could be causing these errors ?

Thanks

James
