Could someone clarify a little question about BGP Confederations, please ? Well, here is the thing: Odom's CCIE R&S Cert Guide v4, page 412, figure 4-10 and example 10-14 have something I cannot grasp.
If sub-ASes use eBGP rules to inform about updates between themselves, why should I use the neighbor next-hop-self command, between different sub-ASes ? The update flying inside AS 123 without change the NEXT_HOP received by R1(sub-AS 65001) and R3 (sub-AS 65023).
