Virtual Chassis Fabric - best practice configuration?

‎01-09-2015 12:19 AM

Hi all,

 

I'm trying to confirm the best practice configuration for QFX5100 Virtual Chassis Fabric.

 

I understand the following commands are required:

 

set system commit synchronize
set chassis redundancy graceful-switchover
set routing-options nonstop-routing
set protocols layer2-control nonstop-bridging

 

But what about these? Do they add any value?

 

set chassis redundancy failover on-loss-of-keepalives
set chassis redundancy failover on-disk-failure

 

Many thanks

Are you looking for an explanation on what these two commands do?

 

If yes, you can check the link below:

 

http://www.juniper.net/documentation/en_US/junos12.3/topics/task/configuration/routing-engine-redund...

 

The first one in combination with GRES, can trigger a failover in 2 seconds in case the RE doesn't send keepalives.

 

I'm not sure about the second one in terms of failover timing improvement.

Since QFX5100 has no internal disk-drive not applicable.
