很郁闷的问题，直连路由死活不通

thinkpad12

做VRRP实验，拓扑如图，两台pc通过两台三层交换sw2,sw3访问位于sw1上面的server，vrrp还没开始配，三台交换机之间开启ospf，起了ospf之后SW3到sw1的直连路由死活不通了，sw3访问sw1先经过sw2，郁闷了，哪位高工帮我看看，问题出在哪里了，路由表看起来没问题，直连路由是存在的，下面把三台SW的配置给贴出来：

做路由最好前先测2层通，

再起OSPF之前二层确实是通的，开启ospf之后直连不通了，关闭ospf之后直连还是不通，郁闷了

没查出问题，不在同一VLAN，也不在同一网段，一个是255.0网段，一个是255.4网段，我怀疑模拟器问题，因为在开启ospf之前，sw2到sw1和sw3到sw1的直连路由都是通的，sw1上用192.168.255.2ping 192.168.255.1,sw2上用192.168.255.6 ping 192.168.255.5都是通的，开了ospf之后sw3ping不通sw1，sw3的mac地址表里面没有255.5对应的mac地址，而sw2ping 192.168.255.1却可以通，我试着换SW3到sw1之间的网段，换vlan都不通，所以我怀疑模拟器有问题

原因找到了，SW2与SW3通过VLAN10，VLAN20的三层接口交换路由信息，我用RIP协议，把vlan10 ，vlan20设成silent-interface，只让SW2，SW3通过vlan100 ，vlan101的三层接口交换路由信息，这样的话，上面的问题就解决了，可是如果还用ospf，上面的问题该如何解决呢@哪位高工给个思路

大家说，我把sw2与sw3配成两个ospf区域，让sw1当边界路由和DR,这样可以么?
