Download XORP 1.3

The internet consists of many different networks that are connected to each other. Routers are often used to connect these networks, which direct the network traffic in the right direction. A number of people at the International Computer Science Institute in Berkeley California are developing an open source platform to perform the functions of a router. It has been given the name XORP and can currently process traffic between different networks based on IPv4 and IPv6. For more information, we refer you to this page. The developers have released version 1.3 with the following patch of changes:

Release 1.3:

ALL:

• Numerous improvements, bug fixes and cleanup.
• XORP now builds on Linux Fedora Core5, DragonFlyBSD-1.4, FreeBSD-6.1.
• Implementation of IGMPv3 (RFC 3376) and MLDv2 (RFC 3810). Those are necessary to complete the Source-Specific Multicast support.

CONFIGURATION:

• Addition of new OSPF configuration statement as part of the MD5 keys:
  • max-time-drift: u32 (default to 3600, ie, 1 hour)

  It is used to set the maximum time drift (in seconds) among all OSPF routers. The allowed values ​​are in the range [0–65535]. If the value is 65535, the time drift is unlimited.

• The following statements for configuring static routes have been deprecated:
  route4, route6, interface-route4, interface-route6, mrib-route4, mrib-route6, mrib-interface-route4, mrib-interface-route6.
  The new replacement statements are:
  route, interface route, mrib route, mrib interface route.
  Each of the new statements can be used to configure either IPv4Net or IPv6Net route.
• The following statements for configuring RIP and RIPng have been renamed:
  • route-expiry-secs -> route-timeout
  • route-deletion-secs -> deletion-delay
  • table-request-secs -> request-interval
  • interpacket-delay-msecs -> interpacket-delay
• The following statements for configuring RIP and RIPng random intervals have been replaced:
  • triggered-update-min-secs and triggered-update-max-secs with triggered-delay and triggered-jitter
  • table-announce-min-secs and table-announce-max-secs with update-interval and update-jitter

  Previously, each interval was specified as [foo-min, foo-max]. Now each interval is specified as [foo – foo * jitter / 100, foo + foo * jitter / 100] where “jitter” is specified as a percentage (an integer in the interval [0, 100]) or the value of “foo”.

• The “version” statement for configuring an IGMP interface/vif allows values ​​in the range [1-3]. Previously, the allowed range was [1-2].
• The “version” statement for configuring a MLD interface/vif allows values ​​in the range [1-2]. Previously, the allowed range was [1-1].
• The following statement for configuring PIM-SM (pimsm4 and pimsm6) has been renamed:
  • interval-sec -> interval
• If a “then” policy block contains “accept” or “reject” statement, now all statements inside the “then” block are evaluated regardless of their position.
• Addition of a new “exit” operational mode command that is equivalent to the “quit” operational mode command.
• The “create” and “set” configuration commands are merged, so now the new “set” command can be used for setting values ​​and for creating new configuration nodes. For backward compatibility, the obsoleted “create” command is preserved as an alias for the new “set” command, though it may be removed in the future.

LIBXORP:

• Few bug fixes in the RefTrie implementation.

LIBXIPC:

• Minor improvement in parsing XML requests.

LIBFEACLIENT:

• No significant changes.

XLR:

• No significant changes.

RTRMGR:

• Various bug fixes.

XORPSH:

• Previously, the “commit” command was not available in configuration mode if there were no pending configuration changes. Now the “commit” command is always available, but the following message will be printed instead: “No configuration changes to commit.”
• Various bug fixes.

POLICY:

• Various bug fixes.

FEA/MFEA:

• Bug fix in transmitting large packets on Linux when using IP raw sockets.
• Linux-related netlink socket code refactoring and bug fix.
• Bug fix in obtaining the incoming interface for raw packets (in case of *BSD).
• Bug fix in parsing the ancillary data from recvmsg().
• Accept zeroed source addresses of raw packets, because of protocols like IGMPv3.
• Bug fix in restoring kernel routes that were automatically removed when the MAC address or MTU on an interface is modified.
• Bug fix in processing IPv4 raw packets if they contain an IP option with a bogus option length.

RIB:

• Several bug fixes and improvements.

RIP:

• Various bug fixes in the MD5 authentication support.
• Remove route flap when applying/deleting RIP-related import policies.
• Fix an issue with INFINITY cost routes that might be bounced indefinitely between two XORP routers.

OSPF:

• Various bug fixes in the MD5 authentication support.

BGP:

• Prefix limits on a per peer basis.
• Various bug fixes.

STATIC_ROUTES:

• No significant changes.

MLD/IGMP:

• Implementation of IGMPv3 (RFC 3376) and MLDv2 (RFC 3810).
• Unification of the IGMP and MLD execution path.

PIM-SM:

• Bug fix related to the SPT switch (the bug is *BSD specific).
• Use the RPF interface toward the BSR when transmitting a Cand-RP Advertisement message. Previously the first interface that is UP was chosen.
• Use the RPF interface toward the RP when transmitting PIM Register messages toward the RP. Previously the interface of the directly connected source was chosen.

FIB2MRIB:

• No significant changes.

CLI:

• Bug fix related to tracking the window size when it is resized.

SNMP:

• No significant changes.
