# -- Notes for updating from Icehouce
The support of ancillary bridges has been removed after Icehouce.
While you can still use these bridges to provide connectivity,
neutron-ofagent-agent no longer reports port state changes (up/down)
for these bridges. If it is a problem for you, please consider
tweaking your configuration to avoid using ancillary bridges.
We recommend to use a provider network instead as the following:
- Make l3-agent external_network_bridge configuration empty.
eg.
[DEFAULT]
external_network_bridge=
- (Re-)create a network (and subnet) for public connectivity with
a flat provider network.
eg.
neutron net-create $PUBLIC_NETWORK -- \
--router:external=True \
--provider:network_type:flat \
--provider:physical_network=$PUBLIC_PHYSICAL_NETWORK
- Associate your neutron router to the above network.
eg.
neutron router-gateway-clear $ROUTER_ID
neutron router-gateway-set $ROUTER_ID $PUBLIC_NETWORK
- Add the corresponding entry to bridge_mappings.
eg.
[OVS]
bridge_mappings=$PUBLIC_PHYSICAL_NETWORK:$PUBLIC_BRIDGE
The port naming scheme for ofagent has been changed after Icehouce.
If you are using security groups, you should switch firewall_driver
accordingly.
From:
[securitygroup]
firewall_driver=neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
To:
[securitygroup]
firewall_driver=neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
