[Rdo-list] (no subject)

[Vedsar Kushwaha]

I changed

neutron subnet-create --name public_subnet --enable_dhcp=False
--allocation_pool start=10.16.37.225,end=10.16.
37.254 --gateway=10.16.37.1 public 10.16.37.0/27

to

neutron subnet-create --name public_subnet --enable_dhcp=False
--allocation_pool start=10.16.37.225,end=10.16.
37.254 --gateway=10.16.37.1 public 10.16.37.0/24 <http://10.16.37.0/27>

and it successfully created.

But I'm still not able to ping to instance. I launched an instance using
demo user. Defined custom TCP and custom ICMP rule in security policy.

Please help...

The error is
[root at localhost ~]# ping 10.16.37.228
PING 10.16.37.228 (10.16.37.228) 56(84) bytes of data.
>From 10.16.37.222 icmp_seq=1 Destination Host Unreachable

10.16.37.228 is the floating IP address of instance.
