我有问题的基本OSPF重新分配到BGP。R10和R12之间的BGP对等点正在上升。
我在0区之间有完整的连接。R10 0/0也在这一领域。我不能让BGP路线从R10->R12重新分配到我的OSPF地区。
如果我将一个default-information originate always语句放在(四位0's)中,这将允许连接。
我创建了R28,并能够让RIP E2路由进入OSPF,所以我不是疯了。R6显示来自RIP的E2路由正在进入。我尝试过每一种BGP再分配方法(例如子网、连通、度量等)。想法非常感激!!
R10路由配置:
R10#sh run | sec router
router ospf 1
log-adjacency-changes
redistribute bgp 65000 subnets
redistribute rip subnets
router rip
version 2
redistribute ospf 1 metric 0
network 172.0.0.0
no auto-summary
router bgp 65000
no synchronization
bgp log-neighbor-changes
redistribute ospf 1
neighbor 15.1.1.2 remote-as 65000
no auto-summary
R10#R6路由表:
R6#sh ip route

根据我在您的网络中所看到的,您正在将172.0.0.0从RIP重新分发到OSPF,而不是在OSPF中创建任何路由。然后,您将OSPF重新分发到iBGP中,但是原始的RIP路由是通过OSPF在另一个路由器中看到的,而不是iBGP。这是正常的,因为OSPF的AD为110,而iBGP的AD为200。基本上,R6信任从OSPF mare接收的任何路由,而不是从iBGP接收的相同路由,因此OSPF路由被安装到它的路由表中,而不是iBGP路由。
