Openstack no route to instance - SSH and PING “No route to host”












1















I have setup my cloud using this official guide about [OpenStack Charms Deployment Guide].(https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html)



My lab is the following:



my lab:



1 IBM System 3540 M4 Maas (500GB HDD - 8GB RAM - 1 Nic)
1 IBM System 3540 M4 Juju (500GB HDD - 8GB RAM -1 Nic)
4 IBM System 3540 M4 Openstack (500GBx2 HDD - 16GB RAM - 2 Nic)
1 Palo Alto Network Firewall


IP plan:



Public Network: 10.20.81.0/24
Private Network: 10.0.0.0/24

Maas: 10.20.81.1
Juju: 10.20.81.2
Openstack: 10.20.81.21-24
Gateway 10.20.81.254
Private Network 10.0.0.0/24
Instance: 10.0.0.9 - 10.20.81.215 (floating)


enter image description here
The problem is that I can not access via SSH to new instance from my Maas server:



$: ping 10.20.81.215
PING 10.20.81.215 (10.20.81.215) 56(84) bytes of data.
From 10.20.81.1 icmp_seq=1 Destination Host Unreachable

$: ssh -i ~/.ssh/id_rsa.pub 10.20.81.215
ssh: connect to host 10.20.81.215 port 22: No route to host


while on node of Openstack that works



$: ping 10.20.81.21
PING 10.20.81.21 (10.20.81.21) 56(84) bytes of data.
64 bytes from 10.20.81.21: icmp_seq=1 ttl=64 time=0.286 ms

I have setup my cloud using this official guide about [OpenStack Charms Deployment Guide].(https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html)



My lab is the following:



my lab:



1 IBM System 3540 M4 Maas (500GB HDD - 8GB RAM - 1 Nic)
1 IBM System 3540 M4 Juju (500GB HDD - 8GB RAM -1 Nic)
4 IBM System 3540 M4 Openstack (500GBx2 HDD - 16GB RAM - 2 Nic)
1 Palo Alto Network Firewall


IP plan:



Public Network: 10.20.81.0/24
Private Network: 10.0.0.0/24

Maas: 10.20.81.1
Juju: 10.20.81.2
Openstack: 10.20.81.21-24
Gateway 10.20.81.254
Private Network 10.0.0.0/24
Instance: 10.0.0.9 - 10.20.81.215 (floating)


enter image description here
The problem is that I can not access via SSH to new instance from my Maas server:



$: ping 10.20.81.215
PING 10.20.81.215 (10.20.81.215) 56(84) bytes of data.
From 10.20.81.1 icmp_seq=1 Destination Host Unreachable

$: ssh -i ~/.ssh/id_rsa.pub 10.20.81.215
ssh: connect to host 10.20.81.215 port 22: No route to host


while on node of Openstack that works



$: ping 10.20.81.21
PING 10.20.81.21 (10.20.81.21) 56(84) bytes of data.
64 bytes from 10.20.81.21: icmp_seq=1 ttl=64 time=0.286 ms

using the following commands I can ping the virtual interface on router u1804Ro from neutron-gateway:



From MAAS



$: juju ssh neutron-gateway/0


then

while the floating IP assigned to instance no way

if I try the ping
