Re: [D] Redundant virtual routers on same host [cloudstack]

GitHub user summer-abacus closed a discussion: Redundant virtual routers on same host

We are running CloudStack 4.22.0 and setup a redundant virtual router. There are three kvm-hosts running.  After setting one kvm host into maintenance mode, we see  that the primary and backup router are on the same host. 

```
(cloudstackdev) 🐀 > list routers listall=true filter=name,state,redundantstate,hostname,
count = 5
router:
+-----------+---------+----------------+----------+
|   NAME    |  STATE  | REDUNDANTSTATE | HOSTNAME |
+-----------+---------+----------------+----------+
| r-8-VM    | Running | UNKNOWN        | srv1-215 |
| r-75-VM   | Running | UNKNOWN        | srv1-215 |
| r-981-VM  | Running | BACKUP         | srv1-215 |
| r-982-VM  | Running | PRIMARY        | srv1-215 |
| r-1063-VM | Running | UNKNOWN        | srv1-213 |
+-----------+---------+----------------+----------+
```

```
(cloudstackdev) 🕊 > list hosts filter=name,state,type,version,
count = 5
host:
+-----------+-------+--------------------+----------+
|   NAME    | STATE |        TYPE        | VERSION  |
+-----------+-------+--------------------+----------+
| srv1-214  | Up    | Routing            | 4.22.0.0 |
| srv1-215  | Up    | Routing            | 4.22.0.0 |
| v-1058-VM | Up    | ConsoleProxy       | 4.22.0.0 |
| s-1059-VM | Up    | SecondaryStorageVM | 4.22.0.0 |
| srv1-213  | Up    | Routing            | 4.22.0.0 |
+-----------+-------+--------------------+----------+
```

Is there a configuration to avoid having the primary and backup router on the same host?
