Replication in sql server

Dear all,

kindly be informed that I want to achieve the next scenario:-

I have two nodes(1,2) on always on and I have another node outside the always on

I want to do replication between the primary database(in always on)

and the third machine(outside always on) and vice versa.

in case the failover the replication occur between the secondary database(new primary) and

the third machine and vice versa.

Many thanks.
