5d3f555234 Many bugfixes in routing table calculation and summary LSA origination. 2005-02-13 23:36:31 +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.

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!!!!

621ccdfe5a Bugfix - options bits were not included in LSAs 
Bugfix - E bit was not unset on stub areas.

3e2bd0f17a Md5 authentification added (unsested).

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

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

0077aab4f9 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
to missing routes or worse to bug()s like "Router parent does not have
next hop" or just segfaults. The patch fixes this but in the long term a
redesign is required here. Note that the patch doesn't worse the
situation, instead it prevents the problems stated. The redesign is
required to handle multiple routes to small subnets properly.

(by Andreas)

Feela, I think that this is at least a good temporary fix, but it's
of course up to you to decide.

d272fe22dd Separated `official protocol names' used in status dumps from name templates 
used for automatic generation of instance names.

	protocol->name is the official name
	protocol->template is the name template (usually "name%d"),
		should be all lowercase.

Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.
