1. It again depends on the sync or no-sync conditions. If you got the sync
enabled you need to have the loopback advertised through an IGP like OSPF in
your case.
If no sync which means all rotuers are on bgp, do not care about advertising
them on IGP. BGP will take care of the NLRI reachablity.
2. I do not think you need to enable authentication in transit area.
I remember when I labed, I had not enabled any auth on the tr area.
thanks
