URL: https://github.com/apache/cloudstack/issues/7838
##### ISSUE TYPE
* Bug Report
##### COMPONENT NAME
* Virtual routers
##### CLOUDSTACK VERSION
CloudStack 4.18.0.0
##### OS / ENVIRONMENT
OS: oracle linux 8
##### CONFIGURATION
- Advanced networking, using **VXLAN**
(http:docs.cloudstack.apache.org/en/latest/plugins/vxlan.html?highlight=vxlan),
having two hosts name is _**kvm001**_ and _**kvm002**_
- The hosts network config:
```
|---------------- cloudbr0: 10.26.128.25 ( VLAN 2128)
kvm001 ------
|---------------- cloudbr1: 10.71.231.41 ( VLAN 2230)
|---------------- cloudbr0: 10.26.128.22 ( VLAN 2128)
kvm002 ------
|---------------- cloudbr1: 10.71.231.42 ( VLAN 2230)
```
- Management Network: VLAN: 2227 (10.71.227.0/24）
- The switch has enabled the following VLANs: 2128, 2230, 2227
The network test is:
```

The Virtual routers is `r-30912-VM` and `r-30911-VM` and the IP is
`10.71.227.33`
```
root@r-30912-VM:/opt/cloud/bin# sh -x checkrouter.sh
+ STATUS=UNKNOWN
+ systemctl is-active keepalived
+ [ active != active ]
+ sed -e s/[,\"]//g
+ awk {print $2;}
+ grep type
+ cat /etc/cloudstack/cmdline.json
+ ROUTER_TYPE=vpcrouter
+ [ vpcrouter = router ]
+ awk {print $9;}+ grep state
+ ip -4 addr show dev eth1
+ ROUTER_STATE=UP
+ [ UP = UP ]
+ STATUS=PRIMARY
+ echo Status: PRIMARY
Status: PRIMARY
root@r-30911-VM:/opt/cloud/bin# sh -x checkrouter.sh
+ STATUS=UNKNOWN
+ systemctl is-active keepalived
+ [ active != active ]
+ sed -e s/[,\"]//g
+ awk {print $2;}
+ grep type
+ cat /etc/cloudstack/cmdline.json
+ ROUTER_TYPE=vpcrouter
+ [ vpcrouter = router ]
+ awk {print $9;}
+ grep state
+ ip -4 addr show dev eth1
+ ROUTER_STATE=UP
+ [ UP = UP ]
+ STATUS=PRIMARY
+ echo Status: PRIMARY
Status: PRIMARY
```
The Result:
- The VM can only ping the VM on same physical hosts
- The VM spawned on different physical hosts cannot ping each other directly
- The VM can ping each other when migrated all VMs to a single host
- The **VPC Redundant router** state are **PRIMARY**
I have restarted the VPC, It can not work.
I have restarted the Virtual routers, It also can not work.
##### EXPECTED RESULTS
The "Virtual routers" works fine.
Are there any commands for further debugging and How to solve this problem ?
