Software update: BIRD 1.2.1

Spread the love

BIRD is a recursive acronym that stands for ‘BIRD Internet Routing Daemon’. The associated program can act as a routing daemon for ipv4 and ipv6 networks. A routing daemon handles the dynamic part of network routing; consider calculating the best route for network traffic based on the available connections and the cost of each connection. For example, it supports multiple routing tables, BGPv4, RIPv2, OSPFv2, and OPSFv3. It was originally developed at the Faculty of Mathematics and Natural Sciences on the Prague Karlovac University and is currently maintained by CZ.NIC Labs. The London Internet Exchange (LINX) and the Moscow Internet Exchange (MSK-IX) among others use BIRD. For more information, we refer you to this page. The developers have now released version 1.2.1 with the following changes:

Version 1.2.1:

  • Option ‘interpret communities’ allows to override implicit handling of well-known communities.
  • ‘configure’ command uses route reload when filters change.
  • Adds router ID of advertising router as OSPF route attribute.
  • ‘show route’ command indicates primary route and shows OSPF Router ID.
  • Configurable date/time formats.
  • Symbol names can be enclosed by ” and so include hyphen and start with number.
  • Several minor bug fixes.

Version 1.2.0:

  • Implements OSPFv3 (IPv6 support for OSPF). Because the code is shared with OSPFv2 and there were deep changes in it, we suggest caution during upgrade to OSPF users. Some advanced features (like NSSA, vlinks and authentication) are not yet implemented.
  • Implements MRTdump – binary logging protocol compatible with other routing daemons. Only BGP part of MRTdump is yet implemented.
  • Changes default value of BGP attribute LOCAL_PREF from 0 to 100. Use ‘default bgp_local_pref 0’ BGP protocol option for the old behavior. The new value is suggested by RFC 4277.
  • Changes default mode of pipes from opaque to transparent. Use ‘mode opaque’ protocol option if the old behavior is needed. Opaque pipe mode is deprecated and might be removed in the future.
