[j-nsp] Graceful restart & Graceful switchover

[William Phang]

I think you may need to delete the "failover on-loss-of-keepalives".

The following config which I have tested with zero packet loss:

chassis {
    redundancy {
        routing-engine 0 master;
        routing-engine 1 backup;
        graceful-switchover {
            enable;
        }
    }

To enable the Graceful-Restart for all protocols use the following config:

routing-options {
    graceful-restart;
   }

We need to configure Grateful-Restart for all protocols which running on the
router. 


Regards,

William

hi,

I am having M40e router with dual RE.

I am facing problem with Graceful swithover. When I do configuration as
follows:

RE1

chassis {
    redundancy {
        routing-engine 0 master;
        routing-engine 1 backup;
        sfm 0 preferred;
        failover on-loss-of-keepalives;
        graceful-switchover {
            enable;
        }

RE0

chassis {
    redundancy {
        routing-engine 0 master;
        routing-engine 1 backup;
        sfm 0 preferred;
        failover on-loss-of-keepalives;
        graceful-switchover {
            enable;

Is this a right configuration for graceful switchover? If yes, then traffic 
should forward through router without interupting.

I am running OSPF,BGP & MPLS on my M40e. Is it necssary to configure 
Graceful-restart for those protocol so that graceful switchover between 
RE's work ?
