Well, can you check if the task requires redundancy to be taken care of ?
They wont tell you to peer with the loopback interfaces directly, but there
can be a subtle hint, likr peering should be independent of the physical
interface or redundancy should be taken care of while establishing the
peerings etc ..
Whenever you peer with an ip address which is not on the segment connecting
the two routers in EBGP, you have to use ebgp-multihop. Also, have use the
update-source so that the peering is established.
Hope it helps
