I dont know the whole scenario here.... but if everything's equal under bgp route selection criteria, then on 65038 as router will select the oldest route as the best route and then then from the lowest router-id (change the router-id for if u want to a route preferred and reboot)

I was wondering about BGP confederation functionality which I experienced on
an IEWB lab (#8) :
Is it true that Confederation peers in different Sub-as'es only will forward
the best prefix to eachother (like IBGP) ?
For example :
AS54 AS54
| |
EBGP EBGP
| |
CONF AS100 CONF AS100
Sub-AS 65267 - Sub-as 65038 - Sub-as65145
Sub-as 65038 will get the same BGP prefixes from both
65267 & 65145, but with different next-hops to AS54.
However, it will select only the best path for a prefix and only send that
further to the next sub-as ? Is this correct behaviour ?
I check Internet Routing Architectures and Routing TCP/IP VOL II but didn't
find something describing this (maybe didn't look good enough).
Thanks and kind regards,
Koen.
