Hi Christoffer,

You don't need a global zookeeper to make geo-replication work. Thus, you
don't need different cluster names as well since you don't need a global
zookeeper.
The existence of a global zookeeper is used for simplifying management of
replication configuration.

All you need to do is let your "standalone" clusters know how to connect to
the other "standalone" cluster, by creating (registering) a cluster at each
side.

Here are the steps to configure geo-replication between two standalone
clusters.

0) assume you have two standalone clusters, one is A, the other one is B.
1) at standalone A, create a cluster "standalone-b" using "bin/pulsar-admin
clusters create". what it basically does is letting standalone A knows how
to connect to standalone B.
2) at standalone B, create a cluster "standalone-a" using "bin/pulsar-admin
clusters create". what it basically does is letting standalone B knows how
to connect to standalone A.
3) at standalone A, create a tenant "my-tenant" and configure the allowed
clusters for "my-tenant" to be "standalone" (standalone A cluster) and
"standalone-b".
4) at standalone B, create a tenant "my-tenant" and configure the allowed
clusters for "my-tenant" to be "standalone" (standalone B cluster) and
"standalone-a".
5) at standalone A, create a namespace "my-tenant/my-ns" and configure the
replicated clusters to be "standalone" and "standalone-b".
6) at standalone B, create a namespace "my-tenant/my-ns” and configure the
replicated clusters to be "standalone" and "standalone-a".
7) util this point, you already setup a bi-direction replication between
standalone-a and standalone-b.

Using this approach, you are able to configure one-way replication or
aggregated replication as well.
