In the end I found out a way to manage mutipath. Outside the bgpd daemon. Basically I evaluate the bgp peer status from ifstated rules and I install/remove static multipath route on variation. The first test seem promising. In the end I can even manage carp based on peer availabilty with this approach.
If someone is interested in conf I can post as well as soon as I finish my test base. Cheers M.

For example if the router is connected to an adjacent host that has assigned itself an address through slaac such that the router has an entry for that particular host in the routing table, then the router will announce the host's /128 address.
