Nope. The reason I am asking for this is, that while attracting traffic
for all the /32 routes, I do not want to clutter my peers routing table
with all that small routes. Since the whole supernet is quite certainly
only used by me and not by my peer, announcing the Supernet does not
harm the integrity.
I tried the method described earlier by Hans.
I prevented the smaller routes from being announced to the peer, they
are still exchanged via OSPF.
I created blackhole routes for the supernets. They are announced via BGP
to the peer with next hop self, but not to the OSPF.
This leads to the small routes not cluttering the peers routing table
and network visibility not changing in my VPN.
This works for me - thank you very everybody :).
Greetings,
Joel
