BGP only advertises the best path, therefore paths which are no longer
the best will be replaced with UPDATEs containing better attributes or
withdrawn completely.
In your case R2 has chosen the paths it learned via R1 as the best, so
it must withdraw the previous best paths it had via R6 from R1.

// R2 does advertise the network to R1 but it stays in R1's BGP table
// momentarily and then gets withdrawn (see debug output below). R2
// and R1 are external BGP peers within confederation 30 so R1 should
// able to receive these updates from R2 - right?
//
// I don't understand why the routes are being withdrawn? Can someone
// explain what I am missing. Thanks in advance for the help.
