Many changes in I/O and OSPF sockets and packet handling.

I/O:
- BSD: specify src addr on IP sockets by IP_HDRINCL
- BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
- Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
- IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO...

Implements OSPF stub router option (RFC 3137).

Also fixes OSPFv3 routing table calculcation w.r.t.
errata 2078 to RFC 5340.

094d2bdb 08/14/2012 02:46 PM Ondrej Zajicek

Implements ADD-PATH extension for BGP.

Allows to send and receive multiple routes for one network by one BGP
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.

bbcfd5a0 07/26/2012 11:59 AM Ondrej Zajicek

just after the LSA is propagated to the other routers.

Minor fixes.

e0a62ad0 05/26/2010 10:32 AM Ondrej Zajicek

If there was the same configured stubnet on local and remote
router, the remote route always won regardless of its cost.

6d04ef89 05/21/2010 02:40 PM Ondrej Zajicek

A fix in OSPFv3 next_hop calculation.

0ea8fb4a 04/24/2010 01:18 PM Ondrej Zajicek

Fixes and enhancements in 'show ospf state' command.

Now it shows a distance, option to change showing reachable/all network
nodes and better handling of AS-external LSAs in multiple areas. The
command 'show ospf topology' was changed to not show stubnets in both...

3b89a232 04/21/2010 07:50 PM Ondrej Zajicek

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.

99f5fc14 01/08/2010 09:19 PM Ondrej Zajicek

A partial vlink fix.

cf0858c2 01/07/2010 09:43 PM Ondrej Zajicek

Another pile of ipa_from_u32() calls.

f98e2915 06/01/2009 12:07 PM Ondrej Zajicek

The pipe cleanup.

3f670371 11/14/2008 08:13 PM Ondrej Zajicek

Bugfix in previous bugfix.

60e04f04 02/18/2005 06:51 PM Ondrej Filip

Minor bugfix: Summary LSA for aggregated area was always propagated with
metric = 1. Now it's metric of most distant component.

27a1e3ac 02/15/2005 04:17 PM Ondrej Filip

Minor bugfixes in routing table calsulation.

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

Many bugfixes in routing table calculation and summary LSA origination.

Minor bugfix in calculation of external routes.

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.

cd092260 06/06/2004 05:03 PM Ondrej Filip

Be sure, that ospf_area is aged before routing table calculation.

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

Small cleanup, indentation and preparation for multiple areas routing table calculation.

2e10a170 06/06/2004 09:37 AM Ondrej Filip

Indentation.

1512813e 06/05/2004 09:28 AM Martin Mares

... and a whole bunch of unused parameters and variables in ospf.

9b133458 06/02/2004 09:14 AM Ondrej Filip

Hotfix for router's parent without nexthop.
It will probably work perfect, but I need to eliminate such situation.

f9625e9a 06/01/2004 02:06 PM Ondrej Filip

Bugfix in external routes calculation.

baa5dd6c 08/23/2003 10:42 AM Ondrej Filip

Finally, next hop problem fixed.

e8ab1680 08/21/2001 03:00 PM Ondrej Filip

Hope, bug in next hop calculation for stub routes fixed.

24c00cb1 06/12/2001 09:10 PM Ondrej Filip

Install route into main routing table just if it's necessary.

e9d3c3aa 06/09/2001 02:55 PM Ondrej Filip

Small bugfix in ext routes calculation.

52fa3e38 09/04/2000 09:21 PM Ondrej Filip

OK, I'm going to advertise 1.0.4.

fdb19982 09/03/2000 10:18 PM Ondrej Filip

Serious bug in ext lsa origination found. Going for 1.0.4.

28a6e1aa 08/17/2000 07:42 PM Ondrej Filip

Stupid bug in next hop calculation of external routes.

059fc1e9 08/16/2000 07:37 PM Ondrej Filip

My calculation of external routes violated rfc. :-(

972fdb45 06/19/2000 03:12 PM Ondrej Filip

Routing table calculation clean up.

0e376168 06/09/2000 06:54 AM Martin Mares

Shut up an uninitialized variable warning.

25a3f3da 06/07/2000 11:34 PM Ondrej Filip

I mark all LSA as in distance INFINITY in process of aging.
I don't have to WALK twice through it.

1186369b 06/07/2000 11:23 PM Ondrej Filip

Doc.

abcbfd04 06/06/2000 02:34 AM Ondrej Filip

Tracing.

2a5d7caa 06/05/2000 04:13 PM Ondrej Filip

I calculated next hop of parent instead of actual LSA. :-(

88048fb3 06/05/2000 03:46 AM Ondrej Filip

Small patch to better hash type=2 LSAs.

273fd2c1 06/05/2000 02:23 AM Ondrej Filip

different mask.
Bugfix in NET lsa origination.
Bugfix in NET hashing.
Bugfix in LSA installing.

df49d4e1 06/04/2000 07:56 PM Martin Mares

Removed lots of trailing newlines in log messages.

Please note that the only calls which don't add newlines automatically
(i.e., don't print a full line of output) are debug() and DBG.
