From 21e90498549fedb59dfe288e866e020bb30e58a3 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 2 Sep 2015 21:42:59 +0900 Subject: server: fix gobgp hang gobgp asks for non existing thing (e.g. local rib for non route server peer), gobgpd doesn't send anything so gobgp will hang up. This fixes gobgpd to send an empty response.
