Re: control link/fabric link failure

Hi Robbie,

The following statement answers your query :-

In the event of a legitimate control link failure, redundancy group 0 remains primary on the node on which it is currently primary, inactive redundancy groups x on the primary node become active, and the secondary node enters a disabled state.

Redundancy group 0 remains primary on the node on which it is presently primary (and thus its Routing Engine remains active), and all redundancy groups x on the node become primary.

This can be found in the following link :-

http://www.juniper.net/documentation/en_US/junos12.1x44/topics/concept/chassis-cluster-control-link-failure-recovery-understanding.html

This essentially means that when there is a control link failure, the RG0 would remain primary on the same node 0 in your case, and all the other RGs would also become primary on the node 0 itself. The node 1 would go into the disabled state to prevent a split brain situation in the network.

Hope this helps.

Sahil Sharma
