From 89e9f82e0b717c0e39bbffa104f9d9f817c19b46 Mon Sep 17 00:00:00 2001 From: Vyacheslav Trushkin Date: Sun, 11 Dec 2011 18:48:47 +0400 Subject: zebra: ZEBRA_HELLO and mopping up routes (BZ#448) ZEBRA_HELLO message is used by routing daemons to inform zebra what type of routes daemon will be announcing to zebra. Also zebra uses route_type_oaths array to track which daemon announces which protocol. Zebra mops up routes if daemon didn't for some reason. --- lib/zclient.c | 21 +++++++++++++++++++++ lib/zebra.h | 3 ++- 2 files changed, 23 insertions(+), 1 deletion(-) (limited to 'lib') diff --git a/lib/zclient.c b/lib/zclient.c index a5d5b7ff..37ee2420 100644 --- a/lib/zclient.c +++ b/lib/zclient.c @@ -318,6 +318,25 @@ zebra_message_send (struct zclient *zclient, int command) return zclient_send_message(zclient); } +static int +zebra_hello_send (struct zclient *zclient) +{ + struct stream *s; + + if (zclient->redist_default) + { + s = zclient->obuf; + stream_reset (s); + + zclient_create_header (s, ZEBRA_HELLO); + stream_putc (s, zclient->redist_default); + stream_putw_at (s, 0, stream_get_endp (s)); + return zclient_send_message(zclient); + } + + return 0; +} + /* Make connection to zebra daemon. */ int zclient_start (struct zclient *zclient) @@ -359,6 +378,8 @@ zclient_start (struct zclient *zclient) /* Create read thread. */ zclient_event (ZCLIENT_READ, zclient); + zebra_hello_send (zclient); + /* We need router-id information. */ zebra_message_send (zclient, ZEBRA_ROUTER_ID_ADD); diff --git a/lib/zebra.h b/lib/zebra.h index 4b4c7c00..ab072d6e 100644 --- a/lib/zebra.h +++ b/lib/zebra.h @@ -417,7 +417,8 @@ struct in_pktinfo #define ZEBRA_ROUTER_ID_ADD 20 #define ZEBRA_ROUTER_ID_DELETE 21 #define ZEBRA_ROUTER_ID_UPDATE 22 -#define ZEBRA_MESSAGE_MAX 23 +#define ZEBRA_HELLO 23 +#define ZEBRA_MESSAGE_MAX 24 /* Marker value used in new Zserv, in the byte location corresponding * the command value in the old zserv header.
