Referring to the exhibit, with Node 0 as primary for Redundancy Group (RG) 1, which action will
the Junos OS chassis cluster take if interface ge-1/0/0 goes down?
A.
RG 1 will remain primary on Node 0.
B.
RG 1 will become primary to Node 1.
C.
RG 1 will become disabled.
D.
RG 1 will remove the interface from the redundancy group.
Weight needs to get down to 0
so,
Priority of RG1 starts at 210
then the failure of ge-1/0/0 with weight of 100
gives you 210 – 100 = 110 which is not 0.
therefore,
RG1 stays primary for Node 0.
Priority and weight are not related.
For RGx to fail over automatically to another node, the software must monitor its interfaces.
When you configure an RGx, you can specify a set of interfaces the RG is to monitor for status, checking whether the interface is up or down.
When you configure an interface for RGx to monitor, you give it a weight value. RGx has a threshold tolerance value initially set to 255. When an interface monitored by RGx becomes unavailable, the software subtracts its weight from the threshold. When the threshold reaches zero, all objects within RGx fail over to the other node.
