RIB size for MLXe8 and cam-partition profile

Hi guys,

I'm looking for an information about the RIB size in Brocade equipment, but I didn't find anything.

 

Could you please help me? Is there any doc about it?

 

My equipment:

2 x BR-MLX-MR2-X

1 x BR-MLX-10Gx20

 

And also, I would like to know if it's possible do edit the cam-partition profile to customize the values, the documentation is not clear about this issue.

 

Current I'm using the profile ipv4-ipv6-2, because we're going to have 3 full bgps. But we're not sure to enable the BGP before get those information.

 

I really appreciate your help.

You do have the right management card to accept full routes for bgp. I have X card and have like 40 bgp sessions up 

with 552925 bgp routes installed.

 

which model is the 10gx20?

-m or -x2?

-m only supports 512k routes

-x2 supports 2million routes

 

You may need to modify the cam space

 

type show default values

 

that'll show you how the cams are separated.

to modify the cams you can change by using 'system-max' command.

look for the info in the docs.

 

system-max vlan 4095
system-max ip-arp 65536
system-max ip-cache 1048576
system-max ip-route 1048576
system-max ip-subnet-port 128
system-max virtual-interface 4095
system-max session-limit 163840
system-max lsp-out-acl-cam 8192
system-max ifl-cam 40960

 

also enable 'enable-acl-cam-sharing'

 

Any modification to the cam-partition profile or system-max requires a reboot for the changes to take place.

Re: RIB size for MLXe8 and cam-partition profile

Hello,

Thanks for helping me.

 

Our interface card is a -X2.

For now I've configured with profile ipv4-ipv6-2

And seems to enough:

 

IP: Raw Size 786432, User Size 786432(0 reserved)
IPv6: Raw Size 131072, User Size 65536(0 reserved)

 

system-max ip-cache 786432
system-max ip-route 786432
system-max ipv6-cache 131072
system-max ipv6-route 131072

 

It looks like the best option for me right?

Re: RIB size for MLXe8 and cam-partition profile

ya that'll work for now. I would just set it to the max value so I won't have to worry about rebooting it in the future.
