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. --- zebra/zebra_rib.c | 36 +++++++++++++++++++++++++++++++++++- 1 file changed, 35 insertions(+), 1 deletion(-) (limited to 'zebra/zebra_rib.c') diff --git a/zebra/zebra_rib.c b/zebra/zebra_rib.c index 8228350f..72633895 100644 --- a/zebra/zebra_rib.c +++ b/zebra/zebra_rib.c @@ -2881,7 +2881,41 @@ rib_sweep_route (void) rib_sweep_table (vrf_table (AFI_IP, SAFI_UNICAST, 0)); rib_sweep_table (vrf_table (AFI_IP6, SAFI_UNICAST, 0)); } - + +/* Remove specific by protocol routes from 'table'. */ +static unsigned long +rib_score_proto_table (u_char proto, struct route_table *table) +{ + struct route_node *rn; + struct rib *rib; + struct rib *next; + unsigned long n = 0; + + if (table) + for (rn = route_top (table); rn; rn = route_next (rn)) + for (rib = rn->info; rib; rib = next) + { + next = rib->next; + if (CHECK_FLAG (rib->status, RIB_ENTRY_REMOVED)) + continue; + if (rib->type == proto) + { + rib_delnode (rn, rib); + n++; + } + } + + return n; +} + +/* Remove specific by protocol routes. */ +unsigned long +rib_score_proto (u_char proto) +{ + return rib_score_proto_table (proto, vrf_table (AFI_IP, SAFI_UNICAST, 0)) + +rib_score_proto_table (proto, vrf_table (AFI_IP6, SAFI_UNICAST, 0)); +} + /* Close RIB and clean up kernel routes. */ static void rib_close_table (struct route_table *table) -- cgit v1.2.1
