Subject: BGP confederation peers

On many labs they specify all configured confederations on all the routers
with the "bgp confederation peer <#> <#> <#>" command. On other labs they
just specify this command on the router in the confederation that does the
ebgp peering to the other confed. Which is correct?
example:
r1)---------r2)-------------(r3

r1 and r2 are in bgp confederation 65511, and r3 is in confed 65550

r2 peers with ebgp to r3.
? Do you put the " bgp confederation peer 65550" command only on r2, or do
you have to put this command on r1 also?

ex:
r1)
router bgp 65511
bgp confederation identifier 19444

r2)
router bgp 65511
bgp confederation identifier 19444
bgp confederation peer 65550 <---- is this command needed on r1 also.

I have used this way for sometime now, but recent Cisco docs, and CCIE labs
shows it configured the other way.

Thanks for reply,
