OSPF MD5 authentication

Hi All,

  I heard(May be I didn't understood properly) that when we use MD5
authentication on OSPF between say R1 and R2,where R1 and R2 as configured
below and when we reload R1,while comming back,R1 will try to use the
youngest key-id(2) to authenticate with R2 for some around 10 minutes and
then it would try to use key-id 1 to get authenticated with R2.Is the stated
above is right,if so,I may be missing something because when I tried this,R1
got neighbor with R2 as soon the device came back after the reload.I am sure
I misunderstood something. Also I tried the same with EIGRP but couldn't
find the above stated characterisics.Please correct me on the same.Thanks
for the help
