Keep in mind that since you don't have interesting traffic defined on
R2, once idle timer is up, r2 will drop the line. Once R1 is about to
broadcast its routing table, it will bring up the line again. The timer
on r1 never goes down to 0, but R2 will.
Either side could drop the line if it doesn't see interesting traffic
passing within idle timer.
