Open Stack

Hi Akash,
Starting the agents is not a problem. The problem is how many l3-agents do
you seen when you do 'neutron agent-list'. I see only one. So my question
was how to I get the individual agents to register separately.

How does this affect your system?

When I create and assign a floating-ip, I do not see anything happening
until I restart the corresponding l3-agent. The reason for this I believe
is that neutron is not sending the rpc call to the correct l3-agent. As a
result the l3-agent has to be restarted, at which It looks up into the db
to sync state, and creates the necessary nat rules for floating-ip.


So we are left with two options
1. Manage multiple external networks with a single agent by unsetting
'external_network_bridge', 'gateway_external_network_id' and 'router_id',
which is what Rafael suggested.

2. Keep restarting the agents everytime you attach a new subnet to router
or create and assign a floatingip .

Either of this is not desirable for me. I am still looking for a good
solution.

Thank you,
Ageeleshwar K
