2018-02-16table/path: Originator ID for locally generated pathsIWASE Yusuke
The current implementation unexpectedly sets "0.0.0.0" as the ORIGINATOR_ID value for the locally generated paths when acting as a Route Reflector. This patch fixes to set own Router ID as the ORIGINATOR_ID value. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2018-02-13packet/bgp: Remove raw binary field on PathAttributeIWASE Yusuke
The current implementation, PathAttribute stores the raw binary data as "Value" field, but this field increases the memory consumption. This patch removes "Value" field to slim down. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>
2018-02-08config: Option to disable best path selectionIWASE Yusuke
Note: When this option is specified, no path will be redistributed to any peer, because there is no best path. Signed-off-by: IWASE Yusuke <iwase.yusuke0@gmail.com>

2018-01-23fix breakage with the latest github.com/satori/go.uuidFUJITA Tomonori
The API has changed with the master branch of go.uuid. GoBGP uses the dependency management tool so it's not problem. However, there are projects using GoBGP as a library and doesn't use a dependency management tool... GoBGP has used a released version of go.uuid so now I have to change Gopkg.toml to use tha master branch. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
2017-12-21cli: Enable to filter EVPN routes by Route TypeIWASE Yusuke
Currently, "gobgp" command supports only to display all routes on RIBs, but with huge RIBs, it is convenient to select routes by a part of NLRI fields. This patch enables to filter routes by EVPN Route Type. For example, when 5 routes for each route type; $ gobgp global rib -a evpn Network Labels Next Hop AS_PATH Age Attrs *> [type:A-D][rd:65000:100][esi:single-homed][etag:10] [10] 0.0.0.0 00:01:09 [{Origin: ?}] *> [type:Prefix][rd:65000:100][etag:10][prefix:10.0.0.0/24] [0] 0.0.0.0 00:00:04 [{Origin: ?} [ESI: single-homed] [GW: 0.0.0.0]] *> [type:esi][rd:65000:100][esi:single-homed][ip:10.0.0.1] 0.0.0.0 00:00:19 [{Origin: ?}] *> [type:macadv][rd:65000:100][etag:10][mac:aa:bb:cc:dd:ee:ff][ip:10.0.0.1] [20,30] 0.0.0.0 00:00:54 [{Origin: ?} [ESI: single-homed]] *> [type:multicast][rd:65000:100][etag:10][ip:10.0.0.1] 0.0.0.0 00:00:33 [{Origin: ?}] You can select multicast route as following; $ gobgp global rib -a evpn multicast Network Labels Next Hop AS_PATH Age Attrs *> [type:multicast][rd:65000:100][etag:10][ip:10.0.0.1] 0.0.0.0 00:03:02 [{Origin: ?}] 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>
2017-12-16table/policy: Support prefix representation in NeighborSetSatoshi Fujimoto
Currently, "neighbor-set" supports only IP address representation and IP prefix representation(such as "192.168.0.0/24") is not supported. This commit enables to accept the prefix representation for "neighbor-set" to allow neighbors to be specified as range. Signed-off-by: Satoshi Fujimoto <satoshi.fujimoto7@gmail.com>

2017-11-24packet/bgp: Sort FlowSpec rules when decoding/creatingIWASE Yusuke
Currently, we sort the FlowSpec rules when creating a new path containing the FlowSpec NLRI and when parsing CLI arguments for the FlowSpec rules. This patch moves sorting the rules into the inside of the "packet" module and sorts them when decoding binary and creating new NLRI. Signed-off-by: IWASE Yusuke <iwase.yusuke0@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.

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>

The local identifier for path is sent to remote peers. To simplify the implementation, 1) the local identifier is unique per prefix not peer. 2) always assign the local identifier even without addpath-rx-capable peer. In the future, we might need to improve 2) to avoid the unnecessary overhead. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
