Upgrade Notes¶

• Python 2.7 support has been dropped. Last release of networking-bagpipe tosupport python 2.7 is OpenStack Train. The minimum version of Python nowsupported by networking-bagpipe is Python 3.6.

• bagpipe-bgp’s old daemon CLI optionaction deprecated since Pike is nowremoved permanently.

New Features¶

• bagpipe-bgp now supports E-VPN with OVS thanks to this new dataplane driver,BGPVPNs of type L2 can now be supported, with both linuxbridge and OVS

• the project now supports the features required for thebgpvpn-routes-controlAPI extension, including: control of local_pref, control of per portroutes, control of redistribution of routes between BGPVPN with next-hopmodified to point to a port.

• Rewrite of the IPVPN dataplane driver for OVS, mainly with theobjective of implementing ECMP using OVSselect groups insteadof themultipath action (which requires maintaining per-flowstate in the datapath, losing wildcarding).

• networking-bagpipe now provides a driver for the networking-sfc project.Using thebagpipe sfc driver will result in the use of BGPVPN stichingroute redistribution, and BGP flowspec for the realisation of a servicechain defined by the networking-sfc API.

Bug Fixes¶

• The IPVPN bgpvpn/router fallback mechanism has been improved. Thismechanism allows traffic not matching any VRF route in the distributedBGPVPN implementation of bagpipe, to “fallback” and reach a Neutronrouter connected on the network. The implementation has been simplifiedand the risk removed of not reaching VRF destinations because of a staleARP entry for the gateway IP. This improvement comes with the requirementof using the OpenVSwitch security group firewall driver onany node having both the l3agent and VMs with a need to reach BGPVPNdestinations (e.g. single node setup or DVR setup).

New Features¶

• Base support was added to allow the use of ‘bagpipe’ driver fornetworking-bgpvpn with the linuxbridge compute node agent, using thekernel network stack MPLS implementation. This is usable although not fullycomplete yet (see bug1627902).

New Features¶

• This release integrates BaGPipe-BGP: rather than depending on the oldbagpipe-bgp version found on github, the recent version of thiscomponent is developped in the networking_bagpipe package itself. Thisversion has been adapted to leverage Openstack libraries for logging,configuration, driver loading, and only rely on packages found in genericOpenstack requirements
