Today shards are allocated to only one node and replica shards are first marked as unassigned and then allocated on an old node. Is this the expected behaviour?

Our expectation, the newly created shards allocate to all 5 nodes (the index settings is 5 shards 1 replica) and same for replica shards. However it's not happening by default.

Now we are checking the option to allocate the shards to all nodes by setting routing from index template.

I am little curious about to know the issue (behaviour of shard allocation) now we are facing. Is it the correct way. Can anyone help on this, please?
