2017-05-10*: support replace-peer-as (aka as-override)Wataru Ishida
we use the term replace-peer-as instead of as-override since openconfig is using it. cli ``` $ gobgp n add <neighbor-addr> as <asn> replace-peer-as ``` config ``` neighbor: config: peer-as: <asn> neighbor-address: <neighbor-addr> as-path-options: config: replace-peer-as: true ``` Signed-off-by: Wataru Ishida <ishida.wataru@lab.ntt.co.jp>
2017-05-10*: support remove private asWataru Ishida

2017-05-10table: Advertise local-pref set by import policyTatsushi Demachi
At importing a path from an external peer, LOCAL_PREF can be set by an import policy but at exporting a best path to an internal peer, this learned, calculated LOCAL_PREF is never used and every time overwritten by a default value 100. According to RFC 4271 "5.1.5. LOCAL_PREF" and "9.1.1. Phase 1: Calculation of Degree of Preference", the learned value should be advertised to other internal peers. This fixes it by just removing resetting a non-local path's LOCAL_PREF by the default value.

2016-11-14policy: fix bug of policy with multiple statementsWataru Ishida
policy can have multiple statements. In each statement, when condition is matched, route-action is finally evaluated after actions with mods. When route-action is 'none', we contine to next statement if it exists. When route-action is 'accept' or 'reject', we stop proceeding. This patch fixes a bug that route-action can't be set to 'none' which means route-action always be set to 'accept' or 'reject' and can't proceed to the next statement.
