Debug发现如下：

*Mar  1 01:46:30.804: OSPF: Rcv hello from 29.29.4.4 area 0 from Serial0/0 29.29.34.4
*Mar  1 01:46:30.804: OSPF: Mismatched hello parameters from 29.29.34.4
*Mar  1 01:46:30.804: OSPF: Dead R 120 C 120, Hello R 30 C 30  Mask R 255.255.255.248 C 255.255.255.0

后来检查，发现时掩码配错了...hub和起来的那个邻居是/29，而起不来的这个是/24。。。

解决办法

Router#config terminal
Enter configuration commands, one per line. 
Router(config)#no service config
Router(config)#exit
Router#copy running-config startup-config
