It begins to sound like a job for a packet capture tool to grab a copy
of a SMC's outgoing broadcast,  and then an Ad Infinitium replay of
the last   30 second  broadcast.      Even with md5 auth;  RIPv2
protocol basically has nothing preventing message replay, so, as long
as your original router is offline such that the  sequence number does
not increase,
and  if  you can continuously replay your router's last RIP broadcast,
 you may  not even need to know any keys......
