Channels - explicit links between protocols and tables

The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.

fe9f1a6d 11/05/2015 11:48 AM Ondrej Zajicek (work)

Initial commit on integrated BIRD

New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible....

Static: Allows to specify attributes for static routes

The patch adds suport for specifying route attributes together with
static routes, e.g.:

route 10.1.1.0/24 via 10.0.0.1 { krt_advmss = 1200; ospf_metric1 = 100; };
2bbc3083 02/21/2015 08:08 PM Ondrej Zajicek

several OSPF routes and some other corner cases in next hop construction
and ECMP. Allows to specify whether external routes should be merged.

Thanks to Peter Christensen for the original patch.

session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

824de84d 06/02/2010 08:25 PM Ondrej Zajicek

Do not start with huge OSPF FIBs.

Most OSPF instances don't need 64k FIB fields. This change halves
resident memory usage on small OSPF networks.

6384c7d7 05/02/2010 05:58 PM Ondrej Zajicek

OSPF: most of summary LSA orig./flush logic rewritten.

Fixes many bugs in the old code and makes it much cleaner.

Fixes and enhancements in 'show ospf state' command.

Now it shows a distance, option to change showing reachable/all network

dca75fd7 02/13/2010 11:26 AM Ondrej Zajicek

Removes phantom protocol from the pipe design.

It seems that by adding one pipe-specific exception to route
announcement code and by adding one argument to rt_notify() callback i
could completely eliminate the need for the phantom protocol instance
and therefore make the code more straightforward. It will also fix some...

Temporary OSPF commit - socket changes.

c27b2449 02/08/2010 03:01 PM Ondrej Zajicek

Shows source (Router ID) for OSPF routes and adds such attribute.

A sad thing is that we does not have a 'router_id' filter type,
so it must be given as decimal number in filters.

cf31112f 01/03/2010 11:17 AM Ondrej Zajicek

Use %R in OSPF when appropriate.

f9bdcad4 07/05/2009 05:01 PM Ondrej Zajicek

Fixes type mismatch in OSPF printf statements.

Mixing ip_addr and u32 does bad things on Ultrasparc.
Although both have the same size. Fascinating.
It was not catched by compiler because of varargs.

38675202 06/11/2009 03:25 PM Ondrej Zajicek

Implements an option that allows to change a set of stub networks.

Changes pipes to transfer all routes between routing table, not just optimal routes.

20e94fb8 05/06/2009 08:02 PM Ondrej Zajicek

A change in OSPF and RIP interface patterns.

Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:...

aebe06b4 11/08/2008 10:33 PM Ondrej Zajicek

Proper format functions for ORIGINATOR_ID, CLUSTER_LIST

f0ad56f4 10/28/2008 03:10 PM Ondrej Zajicek

a3b70dc4 10/26/2008 11:03 PM Ondrej Zajicek

Two new informative CLI commands for OSPF.

Two new CLI commands for OSPF giving nice informative (and still machine
parsable) representation of OSPF network graph (based on datas from the
LSA database).

The first command (show ospf topology) shows routers, networks and stub...

94c42054 03/15/2005 10:06 PM Ondrej Filip

Added new parametr 'rx buffer <num>'. BIRD is able to receive
very large packets (if configured).

63ca37f3 02/20/2005 06:56 PM Ondrej Filip

Cleanup - all unused variables deleted.

52d61a84 02/20/2005 04:54 PM Ondrej Filip

Intelligent reconfiguration should work again.

d8c7d9e8 02/20/2005 04:27 AM Ondrej Filip

Since now I can also use 'dead interval', not just 'dead counter'.

b181f444 02/14/2005 11:54 AM Ondrej Filip

Small changes to reduce number of warnings.

5d3f5552 02/13/2005 11:36 PM Ondrej Filip

Many bugfixes in routing table calculation and summary LSA origination.

86c84d76 07/15/2004 04:37 PM Ondrej Filip

Huge OSPF database redesign. Since now, all LSAs of all areas
are in single database. This avoids duplication of external LSAs and
fixes bug in external LSA distribution.

3b16080c 07/14/2004 09:46 PM Ondrej Filip

Multiple OSPF areas can be attached.
Origination of summary LSA works.
Routing table calculation works.
Virtual links works.

Well, I hope, OSPF is fully compatible with RFC2328!!!!

621ccdfe 07/13/2004 11:58 AM Ondrej Filip

Bugfix - options bits were not included in LSAs
Bugfix - E bit was not unset on stub areas.

3e2bd0f1 06/26/2004 08:15 PM Ondrej Filip

Md5 authentification added (unsested).
Packet receiving clean up.

98ac6176 06/25/2004 04:39 PM Ondrej Filip

A lot of changes:
- metric is 3 byte long now
- summary lsa originating
- more OSPF areas possible
- virtual links
- better E1/E2 routes handling
- some bug fixes..

I have to do:
- md5 auth (last mandatory item from rfc2328)
- !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs)...

1a61882d 06/11/2004 09:36 AM Ondrej Filip

Better routing table calculation. We are ready to work with
multiple OSPF areas.

d5d9693c 06/06/2004 06:45 PM Ondrej Filip

b8f17cf1 06/06/2004 04:00 PM Ondrej Filip

Patch from Andreas Steinmetz <>

d83faf8d 05/31/2004 08:53 PM Martin Mares

static declarations don't belong to includes. (And most of them were
redundant anyway.)

0077aab4 05/31/2004 06:16 PM Martin Mares

The code was broken for external /29 to /32 routes. Assuming that you
have one machine publishing a route to 10.1.1.3/32 and another one
publishing a route to 10.1.1.4/32. If the first machine went down the
route to 10.1.1.4/32 was wrongly killed by the old code, leading either...
