-## Development Loop using CiaB
-
-For service or core development using CiaB, we have a tighter development
-workflow loop which involves tearing down XOS as well as any active OpenStack
-objects (Instances, Networks, etc), rebuilding XOS container images, and then
-redeploying XOS.
-
-We sometimes refer to this as a "mini-End2End" as it does result in a new XOS
-deployment with an E2E test, but does not require a full reinstall.
-
-1. Make changes to your service code and propagate them to your CiaB host.
- There are a number of ways to propagate changes to the host depending on
- developer preference, including using [gerrit
- patchsets](getting_the_code.md#download-patchsets), rsync, scp, etc.
-
-2. Teardown the existing XOS installation and clean up OpenStack to
- remove any leftover instances or networks:
-
-```
-cd ~/cord/build
-make xos-teardown
-make clean-openstack
-```
-
-3. Optional: Teardown ONOS. Sometimes we find it helpful to reinstall the
- onos-cord and onos-fabric containers, to ensure that all state is wiped
- clean from ONOS.
-
-```
-cd ~/cord/build
-make clean-onos

## Dedicating a Fabric Interface for Quagga
-The CORD build process determines which NICs on each compute node are connected to the fabric and puts these NICs into a bonded interface. The name of this bond is fabric, so if you run `ifconfig` on the compute node you have selected to deploy Quagga, you should see this bonded interface appear in the output.

## L3 setup
-The operator will need to allocate a subnet that exists between the CORD POD and the upstream router that is used for peering between the CORD Quagga instance and the upstream routers. CORD currently has a limitation that it requires 2 IP addresses in the peering subnet, so for 1 upstream router we need to allocate 3 addresses in total. This means the peering subnet cannot be smaller than a /29.

-The CORD fabric requires 2 IP addresses so that it can separate peering traffic from data traffic. Peering happens using one of the IP addresses, and the routes in the POD are advertised upstream with the next-hop set to the other IP address. This menas that when traffic comes to the fabric leaf switch from outside, the switch is able to distinguish peering traffic from data traffic and treat each appropriately.

An example of how this is configured is shown in the following figure:
-In this case the peering subnet is `10.0.1.0/24`. The upstream router is using the `10.0.1.1` address. The CORD Quagga is assigned `10.0.1.3`, which is the address used for peering. The upstream router needs to be configured with `10.0.1.3` as its BGP neighbor, and the BGP peering will be established between `10.0.1.1` and `10.0.1.3`.
