Hi,

I'm using icehouse on centos 6.5 that includes controller, compute1, compute2, network and block nodes. I need to extend floating ip range. Additionally, I have to change allocation pool of public network (external network), but it does not seem possible on openstack. For this reason, I tried to create second public network. I created second public network (also second private net and second router) and created new instance, which uses second private network, but it can't access to net.

network structure is as follows:

first public network; 
CIDR : 10.10.10.0/24,
Gateway: 10.10.10.1,
allaocation pool : 10.10.10.32
  • 10.10.10.63

first private network:

CIDR : 10.0.0.0/24,
Gateway : 10.0.0.1,
allocation pool : 10.0.0.2 - 10.0.0.254

First router :

external gateway : 10.10.10.32,
internal interfaca for private net : 10.0.0.1

second public network;

CIDR : 10.10.10.192/29,
Gateway: 10.10.10.1,
allaocation pool : 10.10.10.193 - 10.10.10.198

second private network:

CIDR : 10.1.0.0/24,
Gateway : 10.1.0.1,
allocation pool : 10.1.0.2 - 10.1.0.254

second router :

external gateway : 10.10.10.193,
internal interfaca for private net : 10.1.0.1,

Maybe, I missed something or it's not possible to create second public network. Do you have any idea about the problem? Did anybody experience such a case before?

It's possible to create second external network even with one neutron-l3-agent ( on IceHouse && Juno)

View Multiple external networks with a single L3 agent
What you missed - at first look problem of second external network is problem of tuning second neutron-l3-agent, creating second OVS external bridge, second l3_agent.ini and make it work together ( it's in the past already)
