Ondrej Zajicek c3226991a0 Temporary OSPFv3 development commit 2009-08-21 09:27:52 +02:00
Ondrej Zajicek b082c1bfcc Fixes OSPF on big-endians. 
Hmm, #ifdef is not very typo-safe.
 2009-07-05 20:26:51 +02:00
Ondrej Zajicek 3867520281 Implements an option that allows to change a set of stub networks. 2009-06-11 17:25:38 +02:00
Ondrej Zajicek 3d15dcdb1c Changes OSPF to generate stub networks for non-primary addresses. 
Also does some reorganization in RT LSA announcement.
 2009-06-10 23:45:08 +02:00
Ondrej Zajicek 024c310b53 Fixes broken cryptographic authentication in OSPF 
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.

That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).
 2009-04-08 20:15:01 +02:00
Ondrej Zajicek 8298d780be Better OSPF packet tracing log messages. 
Replaces old OSPF packet tracing messages with
uniform messages with packet dumps.
 2009-04-06 16:17:47 +02:00
Ondrej Filip 94c42054ea Added new parametr 'rx buffer <num>'. BIRD is able to receive 
very large packets (if configured).
 2005-03-15 22:06:36 +00:00
Ondrej Filip e6ea2e375e Maximal packet size in virtual links is 576. 2005-03-15 20:51:33 +00:00
Ondrej Filip e300066d5f OSPF can accept larger packets than MTU. 2005-03-14 11:24:56 +00:00
Ondrej Filip d8c7d9e884 Since now I can also use 'dead interval', not just 'dead counter'. 2005-02-20 04:27:56 +00:00
Ondrej Filip 60e04f0413 Minor bugfix: Summary LSA for aggregated area was always propagated with 
metric = 1. Now it's metric of most distant component.
 2005-02-18 18:51:42 +00:00
Ondrej Filip 9912fa51c8 Bugfix - cost of interface can be larger than 0xffff 2005-02-12 22:18:48 +00:00
Ondrej Filip 8d94a524b6 Added handling of STUB bool. 2004-07-16 08:27:11 +00:00
Ondrej Filip 86c84d76b7 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.
 2004-07-15 16:37:52 +00:00
Ondrej Filip 3b16080c97 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!!!!
 2004-07-14 21:46:20 +00:00
Ondrej Filip 62eee82321 Default tick = 1. The today's CPU is fast enough. 2004-07-13 21:27:33 +00:00
Ondrej Filip 621ccdfe5a Bugfix - options bits were not included in LSAs 
Bugfix - E bit was not unset on stub areas.
 2004-07-13 11:58:50 +00:00
Ondrej Filip 3e2bd0f17a Md5 authentification added (unsested). 
Packet receiving clean up.
 2004-06-26 20:15:34 +00:00
Ondrej Filip 98ac61766d 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)
	- 2328 appendig E
 2004-06-25 16:39:53 +00:00

 2004-06-04 16:30:04 +00:00
Ondrej Filip 39e517d47c hello.c and hello.h cleaned up. No design changes. 2004-06-04 12:53:10 +00:00
Ondrej Filip 035f6acbfe Patch from Andreas Steinmetz <ast@domdv.de> 2004-06-01 13:12:10 +00:00
Martin Mares d83faf8dc4 static declarations don't belong to includes. (And most of them were 
redundant anyway.)
 2004-05-31 20:53:22 +00:00
Martin Mares 4ef3dccfa1 The OSPF authentication type was sent in host byte order instead of of 
network byte order thus breaking interoperability with other routing
daemons on litte endian machines. The patch fixes this but note that
this breaks compatability with older bird installations using OSPF and
password authentication
