In the lab, you would not see the BB1 config, so unless it told you to peer
with loopback0, you wouldnt specify 'update-source looopback 0.'
If it did tell you to use Loopback 0, they would need ebgp-multihop
configured on BB1, and you would need the 'local-as' neighbor option below.
you EITHER change
!BB1 FROM
neighbor 150.1.2.1 remote-as 64514
TO
neighbor 150.1.2.1 remote-as 4
-OR-
ADD
neighbor 2.2.2.2 local-as 64514
----looks like ebgp-multihop is missing on BB1 also.
