quagga 中 ospf最终生成的路由被dump的情况

void
ospf_route_table_dump (struct route_table *rt)
{
  struct route_node *rn;
  struct ospf_route *or;
  char buf1[BUFSIZ];
  char buf2[BUFSIZ];
  struct listnode *pnode;
  struct ospf_path *path;

#if 0
  zlog_debug ("Type   Dest   Area   Path	 Type	 Cost	Next	 Adv.");
  zlog_debug ("					Hop(s)	 Router(s)");
#endif /* 0 */

  zlog_debug ("========== OSPF routing table ==========");
  for (rn = route_top (rt); rn; rn = route_next (rn))
    if ((or = rn->info) != NULL)
      {
        if (or->type == OSPF_DESTINATION_NETWORK)
	  {
	    zlog_debug ("N %s/%d\t%s\t%s\t%d", 
		       inet_ntop (AF_INET, &rn->p.u.prefix4, buf1, BUFSIZ),
		       rn->p.prefixlen,
		       inet_ntop (AF_INET, &or->u.std.area_id, buf2,
				  BUFSIZ),
		       ospf_path_type_str[or->path_type],
		       or->cost);
	    for (ALL_LIST_ELEMENTS_RO (or->paths, pnode, path))
              zlog_debug ("  -> %s", inet_ntoa (path->nexthop));
	  }
        else
	  zlog_debug ("R %s\t%s\t%s\t%d", 
		     inet_ntop (AF_INET, &rn->p.u.prefix4, buf1, BUFSIZ),
		     inet_ntop (AF_INET, &or->u.std.area_id, buf2,
				BUFSIZ),
		     ospf_path_type_str[or->path_type],
		     or->cost);
      }
  zlog_debug ("========================================");
}

dump的结果类似

N 10.1.0.0/24 0.0.0.0 intra-area 10 -> 0.0.0.0

代表

下一跳 下一跳地址/掩码 区域 类型 度量 -> 目的IP

上面结果是

下一跳为10.1.0.0/24
