  EIGRP和OSPF做双点双向重分发
第一种情况：
1，R1,R2,R3,R4初始配置  R1

到这里（电脑自动关机），所有的EIGRP和OSPF邻居关系都建立好了。   2，在R2和R3上做双点双向重分发  R2
router eigrp 1
redistribute ospf 1 metric 10000 100 255 1 1500
router ospf 1
redistribute eigrp 1 metric 100 metric-type 1 subnets
end
 R3
router eigrp 1
redistribute ospf 1 metric 10000 100 255 1 1500
router ospf 1
redistribute eigrp 1 metric 100 metric-type 1 subnets
end 重分发完成，   验证
