Introduction

Neutron dynamic routing project adds the support for dynamic routing protocols in neutron. Using the ReST interface, a cloud administrator can define routing peers and advertise neutron routes outside the OpenStack domain.

Note

Currently, only the support for BGP dynamic routing protocol is available.

Data Model

New data models are defined for supporting routing protocols. Below models are defined for different protocols.

BGP

BGP Speaker

  • id The uuid of BGP Speaker.
  • name The name of BGP Speaker.
  • local_as The local AS value, ranges from 1 to 65535.
  • ip_version The ip address version for BGP Speaker. 4 by default.
  • peers The remote peer connection which supports BGP.
  • networks The tenant networks connected to the BGP Speaker.
  • advertise_floating_ip_host_routes Whether to enable or disable the advertisement of floating ip host routes by the BGP Speaker. True by default.
  • advertise_tenant_networks Whether to enable or disable the advertisement of tenant network routes by the BGP Speaker. True by default.

BGP Peer

  • id The uuid of BGP peer.
  • name The name of BGP peer.
  • peer_ip The IP address of BGP peer.
  • remote_as The remote AS value, ranges from 1 to 65535.
  • auth_type The authentication algorithm. Supported algorithms: none and md5, none by default.
  • password The authentication password for the specified authentication type.

ReST Interface

Different ReST interface are exposed for realizing different dynamic protocol functionality.

Only an administrator have the access to the exposed API’s.
