2010-02-11While looking through this code I figured out that set nexthop self andClaudio Jeker
no-modify are not supported for MP protocols like IPv6. Add support for those and while testing find another bug in the same region. Inverse the check for the return value of memcmp() -- we're interested in equality. Until now IPv6 was running with an implicit set nexthop self on all iBGP sessions. Oups. set nexthop stuff is OK when tested henning@ and sthen@
2010-01-13Add support for BGP MPLS VPN aka RFC 4364. This is only the RDE part soClaudio Jeker
that it is possible to use OpenBGPD as a route-reflector for VPNv4. Some clean up of the BGP MP code so that multiple protocols are easier supported. kroute/kernel support not yet done but comming. OK henning@, reyk@
2010-01-10Generate a EoR marker in the update list instead of sending it independentClaudio Jeker
of the actual update dump. This will get us the right barrier and the EoR is no longer sent way before the actual dump. Currently a nop since graceful restart is turned off (unless you have announce restart yes in the config). put it in henning@
2010-01-09Fix fatalx message.Claudio Jeker
2009-12-18Merge rde_filter_community() with community_match() and kill a uselessClaudio Jeker
indirection.
2009-12-08Big AID change part two. This changes the mp capability into an array ofClaudio Jeker
flags. This makes a lot of code much easier since the comparison is now trivial. Additionally calculate the negotiated capabilities for a session in the SE and pass that and only that to the RDE. This makes the decisions in the RDE a lot easier. OK henning@
2009-12-04Remove a hardcoded AF_INET6 with the correct use of the current AID.Claudio Jeker
Found the hard way by Laurent CARON (lcaron at unix-scripts info)
2009-12-01Use an artificial address family id in struct bgpd_addr and almost everywhereClaudio Jeker
else. Adds conversion functions to map AFI/SAFI and the Unix AF_ values from and into AID used in bgpd. This is needed to support things like MPLS VPN and other upcomming changes that need to play a lot with AFI/SAFI pairs. Mostly mechanical change, henning@ has no particular issues with this. Must go in so that I can continue working.
2009-10-30Routers with "transparent-as yes" set should behave more like iBGP ones.Claudio Jeker
In this case export the MED to all peers no matter what. It is no longer needed to do the set med +0 hack. OK henning@
2009-08-06Implement the error handling as proposed in draft-ietf-idr-optional-transitiveClaudio Jeker
for optional transitive attributes. In short if the partial bit is set on an optional transitive attribute but the attribute fails validation ignore the attribute or mark the path as ineligible instead of killing the session with a NOTIFICATION. Tested, input and OK sthen, OK henning
2009-06-06Some preliminary filter magic to support multiple RIBs on the filters.Claudio Jeker
It is ugly but does the trick for now. Filters will be rewritten anyway. The rib specifier only makes sense on from rules. e.g. deny rib OMG from any
2009-03-26argh, do not reuse the global trans_as flag to be applied to the peerHenning Brauer
specific or we had to widen the peer specific flags without need. defien PERRFLAG_TRANS_AS instead and use that
2009-03-22make transparent-as yes|no settable peer neighbor with the global settingHenning Brauer
acting as default. per-neighbor requested by arnold nipper @ decix, ok claudio
2009-03-13Correctly encode MP unreach NLRI so that IPv6 prefixes get removed correctly.Claudio Jeker
One bug was hiding another bug and only foundry based routers where unhappy about these bad updates. Found by Arnoud Vermeer and Elisa Jasinska at ams-ix. OK henning@
2009-01-13Replace NEW_ASPATH/NEW_AGGREGATOR with the naming from RFC4893,Stuart Henderson
AS4_PATH/AS4_AGGREGATOR. No binary change. ok claudio
2008-12-12Correctly set the partial bit on the AS4_PATH and AS4_AGGREGATOR attribute.Claudio Jeker
Per RFC4271 the partial bit must be set if the attribute was not generated on the originating router. This is mostly cosmetics. OK sthen@
2008-11-01Use correct function names in fatal() messages.Claudio Jeker
2007-11-27Prefixes or actually pathes that would cause a rooting loops should not beClaudio Jeker
dropped when parsed but instead be added to the RIB marked as not eligible. So the decision process does not pick them up as a valid route. Tested and some ideas by Tony Sarendal (tony (at) polarcap (dot) org)
2007-05-31Correctly encode ATTR_NEW_AGGREGATOR. The new aggregator is the one thatClaudio Jeker
bgpd uses internaly so we can just dump that one out. Found by Stuart Henderson, OK henning@
2007-05-29Correctly fill the MP reach and unreach update messages. Until nowClaudio Jeker
short updateds included a dummy ::/0 route and the withdraws were totaly wrong because the AFI/SAFI header was missing. put it in henning@
2007-05-11Various spelling fixes from Stuart Henderson.Claudio Jeker
2007-04-23Make bgpd 4-byte AS compatible. All internal representations of AS numbersClaudio Jeker
are now 4-byte instead of the old 2-byte numbers. The only exception are communities because they can not be switched. The RDE will inflate and deflate the ASPATH and AGGREGATOR attributes on demand and create the NEW_ASPATH and NEW_AGGREGATOR field whenever needed. Both old and new stile sessions are supported and can be mixed. Currently new stile sessions with the 4-byte AS number capability turned on are only enabled if one of the AS numbers involved is a 4-byte one. This is based on an initial diff by Geoff Huston gih (at) apnic (dot) net Cleanup, testing and bug-fixes by myself (via AS 3.10). Currently mrt table dumps are producing incompatible output this will be fixed afterwards -- this diff is already big enough. "get it in if you think it is ready" henning@
2007-04-06Count the updates and withdraws for additional statisic gathering.Claudio Jeker
Discussed with henning@
2007-03-16A few more s/2858/4760/ and use RFC <number> everywhere.Claudio Jeker
2007-03-16Update multiprotocol extension code to RFC 4760. This actually removesClaudio Jeker
a few things we actually never realy cared about. OK henning@
2007-01-31Do not check that the aspath is loopfree for the peer when sending updates.Claudio Jeker
This is an undocumented optimisation that fails with the introduction of AS 23456 as placeholder for 4-byte ASN. OK henning@
2006-11-10char -> u_char in a few placesHenning Brauer
apparently from Jeff Rizzo <riz@NetBSD.org> via "Thomas E. Spanjaard" <tgen@netphreax.net>, ok claudio
2006-04-21Remove function prototype that was never used. From deraadt@Claudio Jeker
2006-04-04add "set nexthop self", force nexthop to be set to own address even with IBGPHenning Brauer
requested & tested Falk Brockerhoff <fb@smartterra.de>, and tony sarendal tested this too. claudio ok
2006-01-13Simplify evaluation process. Instead of checking the reachability of a prefixClaudio Jeker
at many different places do it once. This simplifies the logic and makes it easier to extend it for upcomming Adj-RIB-In addition. OK Henning.
2006-01-12Copy AS path in rde_filter() on demand instead of doing it before callingClaudio Jeker
rde_filter(). Adapt path_update() to this change too. path_update() does a path_copy before linking the rde_aspath into the RIB. Looks good Henning.
2006-01-05Cache optional BGP attributes (mostly communities) and use a simpleClaudio Jeker
pointer plus a ref counter to link the attributes to the path object. Saves +/- 10M on 11 full feeds. Looks good Henning
2005-12-30Use sys/hash.h instead of own built functions that work similar.Claudio Jeker
While there reorder some structs to help with alignment.
2005-11-29Add a flags field to struct prefix which will be used shortly. Remove the peerClaudio Jeker
pointer so that the size does not grow. Adding 4 bytes to struct prefix would result in 64MB more memory usage on one of my systems.
2005-11-29even more spaces and tabs.Claudio Jeker
2005-11-01Softreconfig out support. On config reload filter changes of outgoing rulesClaudio Jeker
will propagte directly to the neighbors. There is no need to restart bgpd in that case. Currently not optimal but a good start. "get it in" henning@
2005-11-01Major cleanup in rde_update.c. Merge equal code used in different placesClaudio Jeker
into own functions. Move up_dump_upcall() into rde.c and rename it rde_up_dump_upcall(). This is needed for the next step. up_test_update() tests if an update or withdraw is needed and up_generate() creates the updates. "get it in" henning@ (he is eager on softreconfig out)
2005-11-01Switch from the per peer filter set list to a filter-only solution.Claudio Jeker
The default filter_sets are converted into match filter rules that get evaluated first. Simplifies code massively -- mainly the config reload part -- and makes softreconfig out a piece of cake. "get it in" henning@
2005-10-19tsc tsc tsc, tabs are not always holyHenning Brauer
2005-08-10Pass the correct peer to rde_apply_set(). rde_apply_set() needs to knowClaudio Jeker
the peer where the prefix came from so that prepend-neighbor works. Extend rde_filter() and make sure that the correct peer is passed. Until now most cases resulted in a NULL peer causing a nasty crash that was found by David Ulevitch. OK henning@
2005-07-29Debugging session at WTH. Fix many bugs in the IPv6 support -- some copy pasteClaudio Jeker
and some more obscure ones. With this is it possible to run IPv6 sessions between two bgpd. OK if it does not break IPv4 hummpa barman Henning
2005-07-29Add another piece to the IPv6 puzzle. This time code to generate MP updates.Claudio Jeker
Does not affect IPv4 minimaly tested for IPv6 because we still don't have an IPv6 capable neighbor. henning@ ya
2005-06-16use prefixlen2mask() instead of doing the bitshifting by hand; fixes theHenning Brauer
zero prefixlen case (32 bit shift on 32 bit val -> undefined result) spotted by Moritz Grimm and otto
2005-03-11Finally commit the transparent-as and nexthop no-modify stuff I wrote on theClaudio Jeker
way to FOSDEM. With transparent-as set to ye bgpd will not prepend his own AS for sent updates. NB the neighbor needs to set "enforce neighbor-as no" or it will not like the received AS paths. With set nexthop no-modify bgpd will change the nexthop as done normaly. OK henning@ man page update with help of jmc@

2004-11-11Store the local v4 and v6 address of a session. For IPv4 sessions the firstClaudio Jeker
IPv6 address with global scope of the interface used by the session is used. In any case the local endpoint of the session is used for one of the two no matter what scope. OK henning@
2004-09-28Add prepend-neighbor feature. Prepend the remote-as n times similar toClaudio Jeker
prepend-self. Only for incomming UPDATEs. OK henning@
2004-08-20Grrr. copy paste error. Dump MED and not local-pref. OK henning@Claudio Jeker
2004-08-13Fix minor issues with IPv6 dumps and add a function for dumping the RIB tableClaudio Jeker
protocol independent. This new dump format is not (yet) supported by the mrtd route_btoa tool. OK henning@
