For 1.1 we are supporting neutron router set-gateway to external network (That is how you turn on source-nat).

If we don’t support external gateway then why are we using “router:external” on networks? Do you have a list of what we support and what we don’t as per the Specs/API’s?

 External networks (external-net)

List networks
Show network details
Create network
Update network
The external network extension is used to specify whether the network is external or not. This information is used by Layer-3 network (router) extension. External networks are connected to a router's external gateway and host floating IPs.

The external network extension adds the router:external attribute to the network resource.

Table 4.3. Network Attributes
Attribute Type Required CRUD[a] Default Value Validation Constraints Notes
router:external Bool No CRU False { True | False } Specifies whether the network is an external network or not.
[a] C. Use the attribute in create operations.

R. This attribute is returned in response to show and list operations.

U. You can update the value of this attribute.

D. You can delete the value of this attribute.

Looks like you are also configuring external gateway.. Per Sachin, we don’t support this.

Subject: Creation of a svc_snat n/w with l3 router

Hi Sachin,
Do we have a blue print on our l3 implementation that I can read.

Once I created the l3 router. I see creation of a svc_snat(l3 router uuid) network with a /29 subnet.

I see a port created with name si_(l3 router uuid)-1_left , but I don’t understand what’s SI (service instance?).

The above ports shows that it is attached, but I can’t figure out what device it is attached to. Device owner also comes as None.
