Please pardon my ignorance on Confederations, as I'm not sure if I am
even properly articulating my question . . .  but here it goes . . . 

 

It appears that R5 is akin to a hub and therefore R2 and R6 are like
spokes with routers behind them in the same sub AS (at least in the case
of R2).  If I'm correct in that statement (and I know I may not be),
then it appears R2 and R6 only need to peer with the hub (R5).  But my
question then is when we enter the commands:

 

R2

bgp confederation 64513 64514

R6

bgp confederation 64512 64513

 

Why do we reference the other Sub AS', and not just 64513 on these two
routers?

 

Thanks for bearing with me on this one!
