2018-04-03packet/bgp: Getter functions for AS segmentIWASE Yusuke
This patch adds getter functions for the segment type and AS list of each segment without using type assertion. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2017-12-20table: fix converting 2bytes to 4bytes AS PATHFUJITA Tomonori
On some conditions, we add some ASes to As4PathParam.AS but don't update As4PathParam.Num (the number of ASes). It breaks serialization of AS4PathParam. Instead of modifying the internal of As4PathParam, let's create a new As4PathParam object. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

2017-11-23table: avoid unnecessary attributes in Path objectFUJITA Tomonori
- withdraw path doesn't need any attributes. - mp reach path doesn't need mp unreach attribute (some bgp speackers send an update message including both mp reach and mp unreach). Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2017-11-03table/message: Send EoR as the last of UPDATE messagesSatoshi Fujimoto
EoR should be sent at the end of the UPDATE messages, but currently, EoR may be sent before RIB. This commit fixes this problem. Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>
2017-08-07table: exclude mpreach and mpunreach attribute for normal v4 updatesWataru Ishida
It is possible that gobgp's v4 path structure contains mpreach or mpunreach attribute. (we store entire path attributes in path structure as they are received) Since we use a NLRI field of BGP update message for v4 updates and don't aggregate update/withdrawal messages for other address families, we need to exclude these attribute before sending out v4 updates. Signed-off-by: Wataru Ishida <ishida.wataru@lab.ntt.co.jp>
2017-08-07table: fix handling of update with both mpunreach and mpreach attributeWataru Ishida
some implementations send a mpunreach attribute piggy backed on an update message. Since it is stored in pathattrs of gobgp's path structure, we need to exclude it before sending out update messages. Signed-off-by: Wataru Ishida <ishida.wataru@lab.ntt.co.jp>

2016-05-31table: fix creation of update message from path with multiple NLRIsFUJITA Tomonori
Fix a bug that gobgp creates a wrong update message from path having MP_REACH with multiple NLRIs. gobgp always allocates a path per NRLI (that is, multiple paths from an update message having MP_REACH with multiple NLRIs). Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
