  • 1.  SRX 5800 - RG0 Failover

    Posted 06-27-2020 00:24

    Hi,

     

    We have a pair of SRX5800 running in an High-availability cluster. We did a manual failover from node0 to node1 and all the BGP peers flapped. Is this the expected behavior and was forwarding of packets afftected during the RG0 failover ?

     

    Is there any feature or configuration that would allow the cluster to failover the RG0 without affecting its dynamic routing protocols?

     

    Regards,

    John

    You will need to configure graceful restart to avoid the bouncing of routing peers.

    Thanks Steve for the response. I see that graceful restart is configured under each routing-instance on our firewall.

     

    If Im understanding it right the BGP peers will still need to re-establish but forwarding will not be affected in any way.

    Sorry, you are right did some tests and while routing state is maintained the peers do still bounce.
