How to use maximum RIB/FIB sizein SRX340/345?

I want to know two things.

 

1. How to confirm current size of RIB/FIB.
2. How to enhance these size to max. (SRX340/345)


According to datasheet (*), It is described as follows.

=====
Route scaling numbers are with enhanced route-scale features turned on
=====

(*)

I searched for the setting method for SRX, but I found only the one for the router as below.

[[Configuring the Junos OS to Allocate More Memory for Routing Tables, Firewall Filters, and Layer 3 VPN Labels]]
http://www.juniper.net/documentation/en_US/junos/topics/task/configuration/junos-software-jtree-memo...

I searched for the command by referring to the above, but it seems that it can not be set with this method with SRX.

 

Best Regards,

GENC

I asked about this to the Japan Pre-sales team and received a response from them.

 

=========================================================================
                  <RIB/FIB> <RIB/FIB>
the feature: Disable -> Enable
SRX340: 600K / 400K --> 1M / 600K
SRX345: 600K / 400K --> 1M / 600K


<Inportant>

If the feature will be change to turn on or to turn off, The device is needed to reboot.

 

If licenses (UTM/IDP) are already installed, this feature can not be turn on (can not commit).

 

After turned on this feature (after commit), these licenses can be installed.
However, UTM/IDP features will not be active.
This is because enhanced-routing-mode feature uses the free memory area by stopping the UTM / IDP daemon.

 

  *This is not documented about UTM/IDP.
    also nothing in datasheet.
    I already feedbacked to doc team.


No method to confirm current size of RIB or FIB and possible to confirm the feature is active or not active only.

 

<how to enable this feature>

 

=====
[edit security]
flow {
enhanced-routing-mode;
}
=====

 

  *this method is not documented.
    japan pre-sales team already asked to create a document about this method to doc team.

 

<confirm the feature status>

 

=====
<root@srx345> show security flow status
Flow forwarding mode:
Inet forwarding mode: flow based
Inet6 forwarding mode: drop
MPLS forwarding mode: drop
ISO forwarding mode: drop
Enhanced route scaling mode: Enabled <------- Disable(default) / Enable
