I suspect you were peering from wrong interface (update-source)
Also then you would need ebgp-multihop

I have clear PINGs to the BB router. No password is required. And even if it
requires authentication it wouldn't show as IDLE with no messages received at
all. Neighborship is between direct ethernet IP addresses.
Also I checked the Ethernet switch on which the routers are connected and no
thing strange at all.
Guys,
If I configured a specific ROUTER-ID for my EDGE router does this affect the
neighborship with the BB router?
In otherwords does the router-id may be a reason for this problem!

Basic question but did you test connectivity to the bb?
Can't overlook the obvious!
And I know you stated that the bb was on the same subnet as your router but
another thing to check is your ip.

Subject: EBGP strange situation
Guys,
I had a strange case with EBGP today. I tried to build a neighbor external
peering between two routers (Edge and BB) linked with Ethernet segment. The
scenario is simple just asks for EBGP peering between the two routers and
consider that BB router expects different AS (Using BGP local-as command
should solve this. But the neighborship never work. When I show ip bgp summa
the BB router is shown as IDLE. And no messages are receieved at all from
it. I enabled debug ip bgp & logg cons 7 but it didn't show any info (I mean
got no loggs regarding this neighbor). Any idea why this may happen?
Thanks
