Hi,
   I have a question about snapshot, after I configure 2 2501 router
connected MODEM to AUX port, and I run RIP both side, and hope they can
exchange routes from R4 to R6, but the line is up and could ping each
other, but I can not see any routing update from R4 to R6.
and I notice it has a error message :

2d02h: RIP-TIMER: periodic timer expired

Here is the configuration and debug/show information.
