re: rip key chains

As a followup, when I debug the routers, it appears that R1 is sending
wrong key. It's sending key1 to R2 instead of key2. How do I correct
this?

thanks!

R1 being the hub and R2/R3 are the spokes via f/r. If I setup both spokes
with the same key # and password, it all works. But when I make one
of the spokes with a different key, it fails. I reverse R2 and R3, and the problem
follows the router trying to authenticate with the second key #. I have
tried both clear text and MD5 with the same results. What am I doing
wrong?

On R1 I have:
key chain test
 key 1
  key-string cisco
 key 2
  key-string cisco2

interface Serial0/0.2 multipoint
 ip address 150.50.100.1 255.255.255.0
 ip rip authentication key-chain test
 frame-relay map ip 150.50.100.2 102 broadcast
 frame-relay map ip 150.50.100.3 103 broadcast

R2:
key chain test
 key 2
  key-string cisco2

interface Serial1/3
 ip address 150.50.100.2 255.255.255.0
 ip rip authentication key-chain test
 encapsulation frame-relay
 frame-relay map ip 150.50.100.1 201 broadcast

R3:
key chain test
 key 1
  key-string cisco

interface Serial1/0
 ip address 150.50.100.3 255.255.255.0
 ip rip authentication key-chain test
 encapsulation frame-relay
 frame-relay map ip 150.50.100.1 301 broadcast
