如下三个 AS 组成的网路中, AS200 向外发布本地网段路由 10.1.1.0/24 。
主要设备配置如下所示。

Peer 1.1.1.1 as-number 200

每次衰减值为 1000 ,且关于衰减的缺省参数为 :
Ceiling Value: 16000
Reuse Value 750
Reach HalfLife Time ( in second ) 900
Unreach HalfLife Time ( in second ) 900
Suppress-Limit: 2000
则 RTB 的本地网段 10.1.1.0/24 连续发生次震荡(中断后又立即回复)后, RTC 上不再有该路由,直到 RTB 该路由的惩罚值小于。

在某路由器上 displaospfv3 的输出如下
Routing Process OSPFv3 ( 1 ) with ID 1.1.1.1
Graceful restart helper enabled
Graceful restart helper srtict-lsa-checking disabled
SPF schedule dela5 secs , Hold time between SPFs 10 secs
Minimum LSA interval 5 secs , Minimum LSA arrival 1 secs
Number of external LSA 0. These external LSAs checksum Sum 0x0000
Number of AS-Scoped Unknown LSA 0
Number of LSA originated 19
Number of LSA received 0
Number of areas in this router is 3
Area BACKBONE ( 0 )
Number of interfaces in this area is 2
SPF algorithm executed 9 times
Number of LSA 3. These LSAs checksum Sum 0x6C29
Number of Unknown LSA 0
Area 0.0.0.1
Number of interfaces in this area is 1
SPF algorithm executed 12 times
Number of LSA 3. These LSAs checksum Sum 0x22F1E
Number of Unknown LSA 0
Area 0.0.0.10
Number of interfaces in this area is 1
SPF algorithm executed 1 times
Number of LSA 3. These LSAs checksum Sum 0x81E2
Number of Unknown LSA 0
那么该路由器共有个接口处于该 OSPFv3 进程内。
