From 67be5b23cd80646c2aa5a9c6a3d373ceecb275b6 Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Sat, 6 May 2000 21:21:19 +0000 Subject: When rte_update is called for an identical route, don't announce anything. Please implement the rte_same hook in your protocols. It should just compare your metrics stored directly in rte, the rest is done by the core. --- nest/rt-table.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'nest/rt-table.c') diff --git a/nest/rt-table.c b/nest/rt-table.c index 832e9ef4..4214d078 100644 --- a/nest/rt-table.c +++ b/nest/rt-table.c @@ -272,6 +272,17 @@ rte_free_quick(rte *e) sl_free(rte_slab, e); } +static int +rte_same(rte *x, rte *y) +{ + return + x->attrs == y->attrs && + x->flags == y->flags && + x->pflags == y->pflags && + x->pref == y->pref && + (!x->attrs->proto->rte_same || x->attrs->proto->rte_same(x, y)); +} + static void rte_recalculate(rtable *table, net *net, struct proto *p, rte *new, ea_list *tmpa) { @@ -284,6 +295,14 @@ rte_recalculate(rtable *table, net *net, struct proto *p, rte *new, ea_list *tmp { if (old->attrs->proto == p) { + if (rte_same(old, new)) + { + /* No changes, ignore the new route */ + rte_trace_in(D_ROUTES, p, new, "ignored"); + rte_free_quick(new); + old->lastmod = now; + return; + } *k = old->next; break; } -- cgit v1.2.3
