Enable OSPF Graceful-Restart on Maestro Security Group (R81.10)

Dear Checkmates,

We have realized, that we obviously lose all sessions, when we add a new interface to our security group and add it into ospf.

set ospf instance default interface bond1.2742 passive on
set ospf instance default interface bond1.2762 area 0.0.0.10 on

Thus I would like to enable OSPF graceful-restart on our securitygroup.

(Although in some comment of C_Atkinson here on the forum it is mentioned, that graceful-restart should not be required, although it refers to Cluster XL?

https://community.checkpoint.com/t5/Security-Gateways/OSPF-drops-on-cluster-failover-since-R81-10-up... 

)

 

 

 

Is there anything I need to consider? We peer with Cisco Switches and I stumbled across:

"graceful-restart feature is an industry standard and Maestro supports it for both OSPF and BGP. That way you don't lose routes. graceful-restart must be supported by the peer and timers need to be in sync. The routes will stay while peering is built up after failover."

Can I assume this matches, since OSPF and graceful-restart helper already work?

Also I saw the following in the GUI:

"OSPF Graceful Restart is incompatible with VRRP preempt" mode. Please disable preempt mode before configuring graceful restart"

Since this is no VRRP Cluster and we already have graceful-restart-helper enabled, I think I can ignore this warning?

 

Do you think it is safe to issue:

set ospf instance default graceful-restart on  ?

 

Thanks in advance and BR,

Thomas

Which Jumbo take is deployed in the environment?

Graceful restart is typically relevant to failover scenarios as different to the symptoms you've described.

Do you see the SMO / DR role change to a different SGM during this process?

Hi Chris, thanks for the quick response:

We run:

HOTFIX_R81_10_JUMBO_HF_MAIN Take: 66

How could I see if the SM0 role changes?

 

We were made aware of this through a team, which mentioned, that they have lost twice all sessions on their machines, and the timestamps matched exactly with the creation of some interfaces and adding them to OSPF.

I also could see, that our loadbalancer lost all connections to servers, sitting behind the firewall, at the same time

To see the current SMO & DR manager (Dynamic routing manager) review the following command output from expert mode:

Thank you:

This is the output - it seems it remained on 1 (though I can't prove that it has been 2 before)
