RIP is a vector distance protocol RFC 1058 a router will send RIP routing info every 30 seconds if it doesnt receive an update from an adjacent router it declares that route dead. After 180 seconds without an update it removes all info from its tables.
Transmit timed out, status 0000, PHY status 782d, resetting...

made me think it might not have gotten an update. RIP is the oldest and lowest level form of routing except for static routing.
