neutron-bsdbridge
Neutron ML2 mechanism driver, L2 agent, and DHCP agent for FreeBSD based on if_bridge(4) and pf(4).
Status
Features
- ML2 mechanism driver that binds ports with
vif_type=bridgeand publishes to Nova - Implements one bridge per Neutron segment for vlan, flat and local networks.
- L2 agent to manage bridge, taps and security group rules
- Port security
- DHCP agent running one dnsmasq per network inside separate VNET jails
Roadmap
- L3 agent for gateway and NAT support
- vxlan segments
- IPv6 tcp and udp security group rules
- metadata agent
Limitations
- IPv6 tcp and udp rules are skipped and this traffic stays blocked
- ARP is not inspected
- Only IPv4 subnets are served by the DHCP agent
Host requirements
Make sure to configure net.link.bridge.pfil_member=1 on the host.
Add to the host pf.conf:
set state-policy if-bound
ether anchor "l2-neutron/port/*"
anchor "l2-neutron/port/*"
Configuration
neutron-server (ml2_conf.ini):
[ml2]
mechanism_drivers = bsdbridge
The agents (bsdbridge_agent.ini, a full sample is in etc/):
