Hi Neelakantam, There refer to provider networks, which are quantum networks that are mapped directory to a specific flat or VLAN network in your data center. Please see this page in the Quantum Admin Guide (and its three sub-sections): http://docs.openstack.org/trunk/openstack-network/admin/content/provider_networks.html
Provider networks are useful if you are implementing a "flat" network scenario, or if you have a data center with existing VLANs already in use, and want to be able to map VMs to those VLAN networks. dan On Mon, Nov 12, 2012 at 3:09 AM, Neelakantam Gaddam <[email protected]>wrote: > Hi All, > > > I have few questions regarding bridge mapping in folsom release. > In the quantum configuration file, there is a config param for bridge > mapping: > > bridge_mappings=default:br-eth1 (ListOpt) Comma-separated list of > <physical_network>:<bridge> tuples mapping physical network names to > agent's node-specific OVS bridge names.
