我在 PeerA 和 PeerB 之间有 2 条等价路径链路，它的所有接口都参与同一个 OSPF 区域。

当我将静态路由 (172.16.2.0/24) 从 PeerB 重新分配到 A 时，广告路由器是否仅生成 1 x 外部 LSA 并将其从 2 条链路中的 1 条链路发送到接收对等方？或者相同的外部 LSA 将通过两条链路发送到接收对等方？

问这个的原因是因为我在 PeerA 中只看到外部 LSA 的 1 个条目，即使在 RIB 中，有 2 x OE2 路由到重新分配的网络（172.16.2.0）

PeerA#show ip ospf database external adv-router 0.0.0.2

如上所述，OSPF 数据库中仅显示 1 个外部 LSA，但 RIB 中显示了 2 个 OE2 路由。
